A bit bored during the full moon so dug out my antique Celestron C90 circa 1985. This is a 90mm Maksutov Cassegrain at a slow f11 / Tstop 14+ f/L 1000mm.

Not only did I have full moon but clouds so most subs were only a hand full of frames - 30 secs at ISO3200 so these pics probably resemble the view through the eyepiece rather than any deep sky masterpiece.

Regor in Vela looks like a little solar system the way the stars are arranged. I think it looks cute.

Not far away is open cluster IC2391 and IC2602 the Southern Pleiades.

Had to snap the jewel box NGC4755 also. This is just 3 x 1 minute subs.

Finally Nova Centauri 2013. As mentioned elsewhere it looks a little red shifted this morning.

So there we have it. Nothing deep. Just a few snaps between clouds. Temperature was quite warm last night so some amp glow around the edges which I should have cropped off.

Great set of images.
Well done.
I especially like the last two.

Thanks Ingrid. It was a bit of fun with the old scope.

Nice. I think there should be more imaging of clusters.

Well there's something I can do. Most like to shoot nebula. I'll try for some big southern clusters with the ED80. I won't be able to go deep though. Too many clouds this time of year.
