hydrogen alpha horsehead from tonight
|
Robert Pitt
The attached is my last "nebula" for the season, as we go into galaxy season... Got about 2.5 hours in hydrogen alpha with my 8 inch f/2 RASA and ASI1600MM before the tree ate it....
Regards, Bob

Absolutely Spectacular! What a way to leave “ nebula season” and now bring on the galaxies ( and globulars!)

Prompted by Bob’s amazing Ha image of the Horsehead Region and looking forward to galaxy and glob season, i would like to share two images taken recently using our 10” RC telescope.

Thanks for the galaxy and glob pics Myron. Time to switch my scope on my mount for one with a bit more focal length (probably my 9-1/4 f/10 until my Hyperion 12.5 f/8 comes back from the spa).

Thanks Myron! I might be able to try a bit more tonight if the weather holds...

Bob,
2.5 hrs. is a long time with f2. What was your 1) exposure time per frame? and 2) number of frames? 3) Does the Ha require something longer? As you know, I am just getting started, but I am currently using 15 secs. for M82. Thanks, Don

Hello Don:
For the horsehead, I was shooting 5 min subs in Ha light for a total time of about 2 hr 40 min. The narrowband filters are very narrow and only let in a small fraction of the total spectrum, plus these are special filters by BAADER for high speed systems (the f ratio will shift the wavelengths, so regular narrow band filters will shift the specific narrow wavelength off for fast scopes, probably <f/4, and certainly by f2). I was frustrated last night trying color (just light pollution filter) in a one shot color camera and sky glow washed out image, unless very short. Your 15 sec exposures are probably about right!
