Thanks Guys.
Mike S. Automated?, you mean the scope?, no, its my home rig.
Jase, bloody hell, there you go, I hadnt thought of useing different combines and merging them, you learn something every day. Rounding eggy stars isnt that hard in PS (double image size, move,halve size), its the poisson reject that screws them before you get to PS, but as you say, different combines mixed is an excellent plan. Yes,OK the stars stay. Its hard to plan useing the F/R or not on each image, given you need a new set of flats each change, and it can depend on how everything looks at the end (too late). The 3nm Ha needs huge exposures for the Lum channel, but is vastly better detail than the the RGB subs. Synth Lum from RGB would look awefull.
Hehe, thanks Alex, Mike and Marcus.
Steve, yes, its an awkward FOV for this elongated object, not wide enough for the whole thing (can go wider, that would mean the ED80, thats far too wide), and even at f10 not eough neb to fill the screen.
No, its not automated persay, apart from the obs closing (and mount switched off) automatically, which is actually a huge advantage on its own.
After totally manual set up, I just use imageing "sequence" in DL (no special software) and off it goes, sometimes for up to 5 hrs straight (no flip), and im inside watching TV or abusing ppl on IIS. When you think about it, cant every scope do that?, it just guides on the same object the whole time and takes frames, changing the filters sometimes. I dont understand why every one who has an obs doesnt do it, theres nothing to do all all while its imaging, easy. M17 was done from about 7pm to 10pm for several clear days, so I didnt need the "autoclose" (only for when it goes to 2-3am).
