Medusa Nebula
This faint nebula, Abell 21, is located in eastern Gemini near the more famous Eskimo planetary. Quite large, fills the BigDog fov at f6. Conditions suspect, seeing average at best, transparency colored by passing hi-cirrus, temp about 40F, but clear none the less, a rarity this winter. Total exposure an hour and a half, but could add Oiii for another hour, but not a lot of it in this thing.
Specifics; Meade 16 LX200 at f6.2 with Starizona reducer for 2500mm efl. Exposed in Atik 460ex mono for 12/5 minHa , 5/2 min for green and blue, used 10 minutes of Ha for pseudo-red. All sub-images binned 2x2 for 0.7 "/pixel. Bad pixel map applied to all subs nothing else. Captured and stacked in Nebulosity, final in Photoshop using layers for RGB , Luminosity (Ha ), and pseudo-hydrogen color (hot pink) for nebula.
Clear skies,
Steve

Re: Medusa Nebula
Fabulous.
I love seeing your images.
I love seeing your images.
Binoculars; Celestron Skymaster 18-40 X 80 zoom, Bushnell7-15 X 35 zoom, a couple of older single speed Bushnells that ride around in the car for weather spotting clarification
Scopes; Tiny little Mak-Cass Celestron c90 spotter scope that lets me count the moons of Jupiter and with which I can see Saturns rings in Mickey Mouse phase
Old Meade 1000mm f/11 that was missing the finder scope and ring so I rigged one onto the barrel using duct tape and a bit of cardboard and that actually works and I can count the moons of Jupiter with this one too.
Meade 6" reflector,(really elderly), found at a yard sale, the tube is a bucket of rust and corroded mirror but the mount and tripod will be recoverable so hooray for that.
Cameras; Mamiya medium format 645 with a couple of polaroid backs and a series of wide angle to 50mm lenses
Konica-Minolta 35mm,Sony alpha dslr's, up to the a900 full frame, mostly got them used because I don't have much money.
