Hi All, with the awful skies we've been having I haven't had much of a chance to get out and do much imaging, however I did get out for a little and manage to try out my 200mm F2.8 Canon lens to see the field of view I'd get, there was a lot of haze on both the nights i tried it out so the resulting images could be a lot better, I also messed up the flats. but as a proof of concept Im quite encouraged.
Anyway, nothing great but here they are

Great Daniel, This is indeed what I am planning to do, get M42 & HH in same picture, with my Leitz lens, but have only been outside about 3 times since the summer!!!!!!!!
Stunning images Daniel.
I wish I could just go outside and take a few images like that.
Well done again.

Thanks guy's, Fay, I just saw your HH you posted, stunning image, I've been thinking of taking a shot like this, then up-resing the image and using as the basis for a mosaic with the hyperstar, thought it'd be a great way to plan a shot.
Daniel
:O)
Those are nice images, Daniel. Strange how you can just "pop outside" and acquire a cracker, whilst carefully planned sessions end in failure..
I think it's one of the nice things about using the 200mm, normally it can take about 2 hours to set up and collimate the hyperstar, and by that time the weather usually takes a turn for the worst, this time I was up and running within about 45 minutes.
Me also - I've also done my own proof of concept of this area of sky:

I think we're all waiting for some decent weather - here's hoping for a clear DSC!
Daniel, that 200mm lens certainly gives a useful field of view and, as you say, very fast to set up. What exposure times did you use for those 2 images?
Mark
Hi Mark, because of the haze I only managed 4:30 seconds per sub on the M31 image at ISO 320, F4 the Orion images was even worse at 1:30s at ISO 320 and I only managed to get 6 images on that occasion.
Hoping when the weather gets better I'll be able to go at least 8 minutes on these.
Daniel

So you got 6 subs @ 90 secs on Orion and X subs @ 270 secs on M31 - what camera ?
Daniel, you're certainly getting good results, but a bit more info please for us mere mortals ;)
Mick
Hi Mick, that was the modified Canon 40D, the M31 shot consisted of 19 Subs (just counted)
Daniel
:O)
Thanks for that Daniel
Was it a mosaic Daniel? I thought not
Hi Fay, no, these are just straight out of the camera, im using the same lens Robert uses for some of his amazing widefield images.
(Funny how in astronomy, what we consider a "widefield" view actually needs a telephoto lens!)
