ASTRO: M78 revisited in color
Back in October I took M78 but the image didn't go deep and was in black
and white. Also I didn't have very good image processing tools so the image wasn't all that satisfying. Last month I redid it over 3 nights due to clouds interrupting me constantly. This time I went deeper to see if McNeil's nebula had left any traces behind but it appears gone for a while. Some Herbig Haro regions down at the lower right show up but no sign of McNeil's nebula or the illuminating star. This is a dirty area of space however. A good cleaning of the area might turn it up again. (I've been pulling too many all nighters of late.) 14" LX200R@f/10, L=3x10', RGB=2x10' all binned 2x2, STL-11000XM, Paramount ME Rick -- Correct domain name is arvig and it is net not com. Prefix is correct. Third character is a zero rather than a capital "Oh". |

(speachless) .... this is such a cool image!! Don't know if I ever will be able to take shots like this (not with curent scope ofcourse ;-) ) .... but it's an inspiration for sure! :-) Menno |

Don't know if I ever will be able to take shots like this (not with curent scope ofcourse ;-) ) ... but it's an inspiration for sure! :-) Menno It came out a lot better than my first effort. Getting good shots is more a function of the mount and processing skill than the scope in my opinion. On a good mount your 130mm f/7 scope should give great shots of this area and include a lot more of the field than I can fit in. Mosaics are beyond me right now. There's another bright reflection nebula just out of the field to the north and more stuff south if I had the field of view to show it. Back in the 60's I bought a $100 150mm f/4 (600mm fl) reflector. While waiting for Meade to get the LX200R OTA's out I put it on the Paramount. Here's a shot of M63 taken with a old used ST-7. Note the oddly distorted galaxy UGCA 342 under the bright star to the right of M63. It is a very low surface brightness galaxy, much dimmer than its stated 17th magnitude would suggest due to it large size. I have no filter wheel for the ST-7 so this is black and white but shows what a scope similar to yours (50% shorter focal length) can do on a good mount. I saved for 30 years before I could afford one. For the last 20 of those I didn't even buy a new eyepiece, it all went in the observatory fund. UGCA 342 is likely the guy responsible for the odd linear dust lane across the "bottom" of M63 and M63 is likely responsible for tearing UGCA 342 to pieces making it just an elongated blob. This was taken in early June when M63 was pretty low in the sky so the stars aren't all that sharp. Also the spider in that scope is too weak for the secondary mirror. I put one in large enough to fully illuminate the field (not just the ST-7's small field). The spider can't carry the load so it is always out of collimation. I want to redo that then see if a field flatener for the STL-11K will turn that scope into a nice wide field scope. Rick Rick -- Correct domain name is arvig and it is net not com. Prefix is correct.
