Mick,

That is a beautiful image. Could you tell us what your exposure time was?

Thanks,

Ron

Thanks Ron and Rich.
Ron, I took the image at the newtonian focus of my SW 6" f5 newtonian using my Canon 350d. I always use ISO 400 and I think this image was a stack of about 5 or 6 30 second exp osures (can't remember exactly as it was a while ago!). It is quite heavily cropped to take out coma affected stars around the edge of the field! I'd been observing the star quite a bit using binoculars and a 'V' filtered SBIG ccd and 55mm lens. I've not observed variables for a while now so I really must make an effort to get back into it!! Carbon stars are my favourites!

Thanks! I'll have to break out my Canon and give it a whirl.

I actually swore off imaging because of all the extra gear and work, but I would love to take a few pictures of my favorite doubles, variables, and carbon stars.

Cheers,

Ron

I'm a sucker for carbon stars. I love them!

Although I haven't observed variables for years, my favorites were RU Peg and Z Cam. They both had an unpredictability to them to keep me tuned in.

I think you should! I was in the same boat. For years obsessed with imaging. Got fairly good given my equipment. But then I realized I was tired of it. Wires and computers, always a fuss.

The Canon I picked up changed all that. For basic shots often a single frame will do ya, like a shot of Alberio I took. 20 secs, done. Perfectly nice shot.

Now I can walk out to the scope with Dslr over my shoulder, snap some basics, and call it good. No fuss. Big improvement for the simple shots anyway.

Oh, and my fav is SS cygni. Easy to find, temperamental but reliably so lol. When I told my girlfriend I'd show her a star she could see change brightness, of course she thought I was nuts. Night after night we'd look, till she could find it immediately in the field on her own. The three stars curved in an arc pointing at it. The two very faint friends in tight.

She started to think I was pulling her leg. No honey, one of these nights you won't be able to find it even though you can see it, because the field will look all wrong. So finally one night, I center it up, it's her turn. Where is it? It's right there. You're tricking me I don't see it. No, find the arc. Hmm, I do see that.... Holy cow it's as bright as the corner star,last nite it wasnt!

All night she went on about seeing a star that changed. She told her friends, no one believes her lol

I have to admit my favorite variables are big, freaky, unstable and unpredictable stars...

Looking at my Favorites List and Notes in SkyTools, my three favorite variables are also color contrasted doubles, making them my three favorite doubles.

I observed for the AAVSO from 1980 to 1992. Since then I have concentrated more on deep sky objects, but I still can find SS Cygni from memory and always enjoy seeing it in outburst.

S Per - I always started at the Double Cluster and hopped my way along to it. I haven't check it in years, though. Lack of time!
