I am considering going after Simeis 147, an old SN remnant in Taurus, just down from M37. I have found this image http://www.eanet.com/kodama/astro/2002/0112/3-3.htm which should help, but am wondering if anyone here has a better finderchart for this object? -- Jay Eads
Jay, I looked at my Sky Atlas 2000 tonight. Find Gamma Aurigae and Zeta Tauri in Taurus. In between those stars is 118 Tauri, which I found last month at my house in St George. I think it is a 4th magnitude star. If you imagine 118 Tauri and Gamma Aurigae as endpoints of a right triangle, the base of that triangle would be in Simeis 147, going east. Or, if you drew an imaginary line between 136 Tauri and 118 Tauri, Simeis 147 is about in the middle of that line, maybe a bit north. I hope this makes sense. Are you going to use your dobsonian reflector? Debbie On Sun, Dec 19, 2010 at 1:25 PM, Jay Eads <jayleads@gmail.com> wrote:

I just looked up the double star 118 Tauri on my double-star list. It's primary star has a magnitude of 5.8 and the secondary star has a magnitude of 6.6. The separation is 4.7 arc-seconds. I wonder if Simeis 147 can be viewed through a rich-field telescope? Debbie On Sun, Dec 19, 2010 at 5:52 PM, Debbie <astrodeb@beyondbb.com> wrote:

Debbie, It is located on chart 5 of the Sky Atlas 2000. Visually it looks like it is best to divide it up into four segments as shown as A, B, C and D on this chart: http://astronomy-mall.com/Adventures.In.Deep.Space/simeis.htm Found these notes on it. Looks like a very difficult target, and one sees by dividing the four sections into smaller sections, and giving a very focused effort. 1st effort is to take SAO 77322, a 6th mag. star and place it in the western edge of the eyepiece and scan slowly east. Using averted vision look for a thin lane of nebulosity, similar to the Veil but less structured. It is possible to see two branches that head off to the north. This is one of the brighter regions of this SN. This can be seen in a 18" scope in 5.0 mag skies. Best seen under dark skies, with really good optics and an OIII filter. One more bright section according to the article is found at RA 5hr 43m Dec +28 degrees 16' or a half of a degree southeast of SAO 77397. If one is in the right area there will be 4 8th to 10th mag stars in a square surrounded by some fainter stars. The stars seem to be embedded in nebulosity. This one requires a dark site with an OIII filter. A third portion is a challenge (a challenge within a challenge) and is at RA 5h 44.5m Dec. +28 degrees 58' This one requires a really good dark site for visual observing. The last challenge is in southern Gemini at RA 05h 39m Dec. +29 degrees 08' near SAO 77354. There is an extremely faint hint of an east-west of nebulosity that curves to the southeast as it passes the star (and from what I've read, it is very faint). So, I am going to give it a try IF the weather ever clears up here or in central/southern Utah. It's one I'll put on my list. On Sun, Dec 19, 2010 at 8:58 PM, Debbie <astrodeb@beyondbb.com> wrote:

Thanks Kurt! Jim's image looks good. Joe, yes, hard visual and probably a hard object to image as well. Well worth it in my opinion, the width of 7 full moons and its around 99,000 years old! On Sun, Dec 19, 2010 at 11:11 PM, Joe Bauman <josephmbauman@yahoo.com>wrote:

Check out APOD, it features Simeis 147 and an eclipsed moon. 7x width of full moon may be an underestimate, binocs with nebula filters may be best equipment to view it.
