Observing Galaxies in Pegasus 01 October 2015 23:07
Observing galaxies in Pegasus 01 October 2015 23:07 Context As you look towards Pegasus you are looking below the galactic plane under the Orion spiral arm of our galaxy. The Perseus-Pisces supercluster wall of galaxies runs through this constellation. It stretches from RA 3h +40 in Perseus to 23h +10 in Pegasus and is around 200 million light years away. It includes the Pegasus I group noted later this document. The constellation is well placed from mid summer to late autumn. Pegasus is a rich constellation for galaxy observing. I have observed 80 galaxies in this constellation. Relatively bright galaxies This section covers the galaxies that were visible with direct vision in my 16 inch or smaller scopes. This list will therefore grow over time as I have not yet viewed all the galaxies in good conditions at maximum altitude in my 16 inch scope! NGC 7331 MAG 9 This is the stand out galaxy of the constellation. It is similar to our milky way. Around it are a number of fainter NGC galaxies. I have seen the brightest one, NGC 7335 in my 10 inch scope with averted vision. I have seen NGC 7331 in my 25 x 100mm binoculars. NGC 7814 - Mag 10 ? Not on observed list ? This is a very lovely oval shaped galaxy. By constellation Page 1 NGC 7332 MAG 11 / NGC 7339 MAG 12 These galaxies are an isolated bound pair about 67 million light years away. NGC 7339 is the fainter of the two galaxies at the eyepiece. I have seen NGC 7332 in my 25 x 100mm binoculars. -

Making a Sky Atlas
Appendix A Making a Sky Atlas Although a number of very advanced sky atlases are now available in print, none is likely to be ideal for any given task. Published atlases will probably have too few or too many guide stars, too few or too many deep-sky objects plotted in them, wrong- size charts, etc. I found that with MegaStar I could design and make, specifically for my survey, a “just right” personalized atlas. My atlas consists of 108 charts, each about twenty square degrees in size, with guide stars down to magnitude 8.9. I used only the northernmost 78 charts, since I observed the sky only down to –35°. On the charts I plotted only the objects I wanted to observe. In addition I made enlargements of small, overcrowded areas (“quad charts”) as well as separate large-scale charts for the Virgo Galaxy Cluster, the latter with guide stars down to magnitude 11.4. I put the charts in plastic sheet protectors in a three-ring binder, taking them out and plac- ing them on my telescope mount’s clipboard as needed. To find an object I would use the 35 mm finder (except in the Virgo Cluster, where I used the 60 mm as the finder) to point the ensemble of telescopes at the indicated spot among the guide stars. If the object was not seen in the 35 mm, as it usually was not, I would then look in the larger telescopes. If the object was not immediately visible even in the primary telescope – a not uncommon occur- rence due to inexact initial pointing – I would then scan around for it. -

My Finest NGC Album
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. -

We present results for the Sbc galaxy NGC 4258, from Canada France Hawaii Telescope data. Thanks to water masers with Keplerian rotation in a circumnuclear disk, NGC 4258 has the most precisely measured extragalactic distance and supermassive black hole mass to date. The globular cluster (GC) candidate se- ∗ 0 0 lection is based on the (u − i ) vs. (i − Ks) diagram, which is a superb tool to distinguish GCs from foreground stars, background galaxies, and young stellar clus- ters, and hence can provide the best number counts of GCs from photometry alone, virtually free of contamination, even if the galaxy is not completely edge-on. -
