Spring Astrocamp 2014 SPRING 2018 WELCOME TO ASTROCAMP Thank you for booking and welcome to the Spring AstroCamp 2018! We’ve resisted the temptation to grow to accommodate more bookings and have stayed at the familiar AstroCamp campsite in Cwmdu, which means we remain small, friendly and continue to be perhaps the most exclusive starparty around! AstroCamp has become widely regarded as the friendliest and most helpful star party there is. So, if you’re feeling sociable, come and set up around 'The Common', near the reception and the AstroCamp HQ tent. If you’re new to astronomy or don’t have your own telescope and want to look through a range of scopes and ask questions, The Common is the place to come! Our gatherings are always friendly so, if this is your first starparty, you can be guaranteed to leave with far more friends than you could imagine and an informed passion for the wonders of the night sky. So don’t be nervous about coming on your own – we’ll make you feel welcome as our newest member of the AstroCamp family! Of course, those that want to find a dark and quiet corner for some observing or imaging in blissful seclusion have everything they want in this weather protected valley under some of the darkest skies in the United Kingdom, here in the Brecon Beacons International Dark Sky Reserve. In 2017 we even obtained a specific directive from the Welsh Cabinet Secretary to turn off the local village’s street lights during AstroCamp events, making Cwmdu truly Wales’ Astronomical Village. In this pack, you find a guide to the scheduled events and talks that will be taking place this AstroCamp. All talks, & events are included in your admission, so please feel free to come along to any or all that you’d like. We've also listed our favourite objects this time of year, as a starter for planning your observations or getting started in imaging over the weekend. All the observation times are listed in UK local time. Apart from the Astronomers in the Pub event on Sunday afternoon, all workshops will begin from the AstroCamp HQ tent on 'The Common'. The Sunday afternoon talks & quizzes will be held at the Cwmdu Village Hall (our pop-up pub, The Spiral Arms, so that we can carry on the tradition of Astronomers in the Pub now that we’ve actually outgrown the village pub). This is easy to find and a short walk from the campsite: from the Farmer’s Arms pub, continue north on the A479 and turn left after 140m. All events are free, there are prizes worth many more times the cost of AstroCamp admission and we even have our own locally brewed AstroCamp Ale for the real ale drinkers. HOW TO GET TO ASTROCAMP By Train: The nearest train station to Cwmdu is Abergavenny. Bus services run weekly to Cwmdu so booking a taxi from the train station is recommended. Taxis cost around £25 each way, but most operators seem to be happy to negotiate a fixed price if you guarantee that you will use them for the return journey. There are often people looking to taxi-share on our Facebook page so you might want to check that out too, By Car: Cwmdu Caravan & Camp site is located four miles north of Crickhowell just off the A479 Turn right at the Farmers Arms public house in the small village of Cwmdu and follow the signs for 300m. PLEASE NOTE: While SATNAV may bring you successfully to the area it may NOT deliver you to the campsite. Please follow the "camping" road signs from the Farmers Arms public house for the final 300m to the campsite. Campsite Address: Cwmdu Campsite, Cwmdu, Crickhowell, Powys, NP8 1RU CAMPSITE LAYOUT Please pitch in your allocated area according to the map below. Please only park your car by your tent if it fits well within the dimensions of your chosen pitch (5x5m small, 8x8m large). Otherwise please park your car in the empty bottom field after unpacking and pitching up. Your neighbour will thank you for it!

Leave campsite and book for 8-11th September AstroCamp The Common (in the middle of the campsite) is the area we’ve created for socialising and observing together. There’s always lots gathered here to share eyepiece views and learn new astronomy tricks from others. Join us in the AstroCamp family at The Common! RALPH'S DSO IMAGING TARGETS FOR BEGINNERS My picks are all visible in a 4” (100mm) scope and can be imaged in 1 minute exposures with a tracking mount. With a good polar alignment, you may be able to take 3 minute exposures or longer. But look at them carefully and if the stars look like they’re smearing, discard them and take slightly shorter exposures or refine your polar alignment. Of course, a dedicated tracking set up will allow you to take longer exposures and obtain better quality images but all of my deep sky picks in this guide will easily show up in shorter exposures if you’re trying out imaging night sky objects for the 1st time or are wanting to see just how far you can push your camera exposures. M65, M66 & NGC3628 - THE LEO TRIPLET This is a unique treat for amateur observers, giving us, as the name suggests, 3 galaxies in the same eyepiece view. The Triplet is at its most advantageous position just before 11pm but will be enjoyable all night. All three galaxies are spiral galaxies, like our own Milky Way, and each presents a different orientation: M66 isn’t quite ‘face on’ but shows us more of its spiral arms than the others, while NGC 3628 is perfectly ‘edge on’ showing a thick dust seam running through the centre under higher magnification. To locate these three galaxies, draw a line between the brightest star in Leo, Regulus in the lower chest of the lion, to Bright Denebola in the lion’s tail. About two thirds the way along that line sits the Leo Triplet. Start with a low power eyepiece to locate them and increase the magnification to frame them all perfectly. To get any level of detail from these distant objects will require exposures of 5 or 10 minutes and, as always, the more the merrier. But if you don’t have a guidescope, you can take shorter exposures of a couple of minutes (or as long as you can take before the stars appear smudged) and stack them together in the free Deep Sky Stacker software. M51 - THE WHIRLPOOL GALAXY Nice and high as soon as it’s dark, the whirlpool is a unique target for amateur astronomers as it gives us views of a spiral galaxy devouring a gravitationally bound smaller galaxy. Follow a line from the Mizar to Alkaid, the end star in the handle of the Plough (Ursa Major). M 51 is half that distance again from Alkaid. A one minute DSLR exposure will show the two galactic cores, while increasing the exposure times will reveal ever more detail. Visually, anyone with a 4 inch or larger telescope should be able to spot its characteristic details. Anyone with a 12-inch telescope may be able to find the companion M51b just behind the main disk, where streams of dust and stars are pouring towards the whirlpool. M13 - THE GREAT GLOBULAR CLUSTER IN HERCULES Getting higher in the sky as the night goes on, and therefore better to observe or image, M13 is still high enough in the sky to observe as soon as it’s dark. To find it, look two thirds the way along a line imagined between the stars zeta and eta Herculis in the keystone shaped asterism in Hercules. This is the largest and most spectacular globular cluster for northern hemisphere observers. M13 is a gravitationally bound ball of more than a quarter of a million stars, 22 light years away in a halo around our galaxy. Don’t miss the chance to see M13 through one of the bigger scopes at camp to see why this wonder has become a firm AstroCamp favourite.

TAKAMIYA1,2 Department of Astronomy and Astrophysics, University of Chicago, Chicago, IL 60637; and Gemini 8 m Telescopes Project, 670 North Aohoku Place, Hilo, HI 96720 Received 1998 August 4; accepted 1998 December 21 ABSTRACT The evolution of the structure of galaxies as a function of redshift is investigated using two param- eters: the metric radius of the galaxy(Rg) and the power at high spatial frequencies in the disk of the galaxy (s). A direct comparison is made between nearby (z D 0) and distant(0.2 [ z [ 1) galaxies by following a Ðxed range in rest frame wavelengths. The data of the nearby galaxies comprise 136 broad- band images at D4500A observed with the 0.9 m telescope at Kitt Peak National Observatory (23 galaxies) and selected from the catalog of digital images of Frei et al. (113 galaxies). The high-redshift sample comprises 94 galaxies selected from the Hubble Deep Field (HDF) observations with the Hubble Space Telescope using the Wide Field Planetary Camera 2 in four broad bands that range between D3000 and D9000A (Williams et al.). The radius is measured from the intensity proÐle of the galaxy using the formulation of Petrosian, and it is argued to be a metric radius that should not depend very strongly on the angular resolution and limiting surface brightness level of the imaging data. It is found that the metric radii of nearby and distant galaxies are comparable to each other.

  • Nuclear Properties of Nearby Spiral Galaxies from Hubble Space Telescope NICMOS Imaging and STIS Spectroscopy
    Nuclear Properties of Nearby Spiral Galaxies from Hubble Space Telescope NICMOS imaging and STIS Spectroscopy.1 M. A. Hughes1, D. Axon11, J. Atkinson1, A. Alonso-Herrero2, C. Scarlata7, A. Marconi4, D. Batcheldor1, J. Binney6, A. Capetti5, C. M. Carollo7, L. Dressel3, J. Gerssen12, D. Macchetto3, W. Maciejewski4,10, M. Merrifield8, M. Ruiz1, W. Sparks3, M. Stiavelli3, Z. Tsvetanov9, ABSTRACT We investigate the central regions of 23 spiral galaxies using archival NICMOS imag- ing and STIS spectroscopy. The sample is taken from our program to determine the masses of central massive black holes (MBH) in 54 nearby spiral galaxies. Stars are likely to contribute significantly to any dynamical central mass concentration that we find in our MBH program and this paper is part of a series to investigate the nuclear properties of these galaxies. We use the Nuker law to fit surface brightness profiles, derived from the NICMOS images, to look for nuclear star clusters and find possible extended sources in 3 of the 23 galaxies studied (13 per cent). The fact that this fraction is lower than that inferred from optical Hubble Space Telescope studies is probably due to the greater spatial resolution of those studies. Using R-H and J-H colors and equiv- alent widths of Hα emission (from the STIS spectra) we investigate the nature of the stellar population with evolutionary models. Under the assumption of hot stars ionizing the gas, as opposed to a weak AGN, we find that there are young stellar populations (∼10–20 Myr) however these data do not allow us to determine what percentage of the 1Centre for Astrophysical Research, STRI, University of Hertfordshire, Hatfield, Hertfordshire, AL10 9AB, UK.

  • The Caldwell Catalogue+Photos
    The Caldwell Catalogue was compiled in 1995 by Sir Patrick Moore. He has said he started it for fun because he had some spare time after finishing writing up his latest observations of Mars. He looked at some nebulae, including the ones Charles Messier had not listed in his catalogue. Messier was only interested in listing those objects which he thought could be confused for the comets, he also only listed objects viewable from where he observed from in the Northern hemisphere. Moore's catalogue extends into the Southern hemisphere. Having completed it in a few hours, he sent it off to the Sky & Telescope magazine thinking it would amuse them. They published it in December 1995. Since then, the list has grown in popularity and use throughout the amateur astronomy community. Obviously Moore couldn't use 'M' as a prefix for the objects, so seeing as his surname is actually Caldwell-Moore he used C, and thus also known as the Caldwell catalogue. http://www.12dstring.me.uk/caldwelllistform.php Caldwell NGC Type Distance Apparent Picture Number Number Magnitude C1 NGC 188 Open Cluster 4.8 kly +8.1 C2 NGC 40 Planetary Nebula 3.5 kly +11.4 C3 NGC 4236 Galaxy 7000 kly +9.7 C4 NGC 7023 Open Cluster 1.4 kly +7.0 C5 NGC 0 Galaxy 13000 kly +9.2 C6 NGC 6543 Planetary Nebula 3 kly +8.1 C7 NGC 2403 Galaxy 14000 kly +8.4 C8 NGC 559 Open Cluster 3.7 kly +9.5 C9 NGC 0 Nebula 2.8 kly +0.0 C10 NGC 663 Open Cluster 7.2 kly +7.1 C11 NGC 7635 Nebula 7.1 kly +11.0 C12 NGC 6946 Galaxy 18000 kly +8.9 C13 NGC 457 Open Cluster 9 kly +6.4 C14 NGC 869 Open Cluster

These spectra are being used to determine the velocity field of nuclear disks and hence to detect the presence of central massive black holes. Here we present the spectra for the successful observations. Dust obscuration can be significant at optical wavelengths, and so we also combine the STIS images with archival Near-Infrared Camera and Multi-Object Spectrometer H-band images to produce color maps to investigate the morphology of gas and dust in the central regions. We find a great variety in the different morphologies, from smooth distributions to well-defined nuclear spirals and dust lanes. Key words: galaxies: nuclei — galaxies: spiral 1.

    My Finest NGC Album A detailed record of my journey through The Royal Astronomical Society of Canada’s Finest NGC list Name: ______________________________ Centre or Home Location: ______________________________ The New General Catalogue or NGC contains 7,840 entries and forms the core of most people's "life list" of observing targets. The NGC was originally published in 1888 by J.L.E. Dreyer and therefore predated photographic astronomy. The Finest NGC list, compiled by Alan Dyer complements the Messier List, as there is no overlap. The list features many fine deep-sky treasures as well as a few somewhat more challenging objects. Once you have observed all of the objects on this list, application forms can be found on the RASC website at www.rasc.ca. The FNGC certificate has been awarded since 1995. Here is an overview of the Finest NGC Observing List Finest NGC Objects Number Notes Open Clusters 12 Including the famous Double Cluster in Perseus, NGC 7789 in Cassiopeia, and NGC 6633 in Ophiuchus. Globular Clusters 2 NGC 5466 in Bootes and NGC 6712 in Scutum. Diffuse Nebulae 14 Includes the great Veil Nebula as well as the North America and Rosette nebulae. Planetary Nebulae 24 Includes many fine PN's like the Ghost of Jupiter, the Cat's Eye, the Blinking Planetary, the Helix, the Blue Snowball, and the Clown Face nebulae. Galaxies 58 Includes the amazing NGC 4565 in Coma Berenices, NGC 253 in Sculptor, and NGC 5907 in Draco. Total 110 The Finest NGC list can be started during any season. Why Record Your Observations? Recording observations is important for two reasons.

    6726 1 Scott N. Harrington 2nd edition September, 2018 2 To my family, Who were always understanding of my excursions under the stars. To the late Jack Horkheimer, a.k.a. Star Gazer, Whose television show kept this young astronomer inspired during those crucial first years. I’ll never stop “looking up”. And in memory of my dog Nell, who kept me company many long evenings – especially the one just before she passed away peacefully at the age of fifteen. I owe her a thanks for helping me with my observations by making this young astronomer feel safe at night. You will always be my favorite of our dogs. 3 Acknowledgements Below is a list of books that I read (most for the first time) in the last few years. They were all deeply influential in helping me discover many of the toughest objects that fill out my list. I would like to note that one I have not read, but greatly look forward to doing so, is Richard P. Wilds Bright & Dark Nebulae: An Observers Guide to Understanding the Clouds of the Milky Way Galaxy.
