Here's a shot of ... guess what?
That I'm pretty happy with considering. I did that last night with the C11 and the new corrector.
I don't think the moon is a real bother at all when you do long FL on a bright object. With the spacing tubes and all this is probalbly close to 3.5m FL. Image scale is under 0.5asp.
I have some massive field problems at that FL that I need to sort out with spacing and alignment but the details are there and I'll get there eventually. Chonky stars close up... and micro guiding issues but the AO will level all this.
Exposure time is 29x3min with the QHY8 - no filter. I guided with the QHY5 on a 8x50mm GSO finder. Only lost a couple of subs due to clouds passing but it got 100% clear after 1:00am and I finished on M16 pillars area which I'll try to process later.
I'm excited about this shot because although there are a lot of things wrong with it starting with the star field and shapes it shows potential and when I get the SCT new laser collimation kit I should be very very close to the sweet spot.
Enjoy the pic. There's a higher res
here [750KB] and a 1:1 full field
here [1.7MB].
PS: on another note if you haven't upgraded to CCDStack version 2 do it. It's so much faster and not as RAM hungry as the older version was. I can now stack 20+ subs in one go on a 2GB RAM XP machine. Before I could only do batches of 10.
PPS: sorry Mike
