Eta carina, M42 through 6 inch F3.6 Schmidt Newt.

Hi everyone
With my 10 inch scope's mirror with Qhi Qin co in Campsie being aluminised/overcoated I cant do any imagign with it so got this old makeshift wooden mounting setup where I can put on my 6 inch F3.6 meade Cometracker Schmidt newtonian and an old "Kmart Special" ex Halleys Comet 3 inch cadadioptric guidescope onto my 10 inches "Sampson" mount. This is the first time Ive used the modded 350D with the 6 inch.

First shot is M42, 2 x 240 sec ISO 200
Next is Eta carina, 2 x 90 sec ISO 1600. Both using UHCS filter and processing by Iris , Photoshop and Noiseware. Sky was over 50% cloudy, I was shooting in between breaks, and thats what limited my exposure times with Eta carina, as well as M42 (I would have gone longer with more exposures if clear.
I cant use my coma corrector on this scope as the cleap n nasty focusser 2 inch adaptor it came with wont grip it firmly enough, so there is some coma present.
