ASTRO: NGC 5189
Another PN imaged in Namibia, this time in the constellation of the fly.
NGC 5189 Date May 31 2011 Location Kiripotib, Namibia Meade 14" ACF at 2340mm focal length (APCCDT67 reducer) camera/filters SXV-H9, Baader LRGB 15x30 seconds each mount/guiding MK100/OAG/Lodestar/AstroArt5 http://ccd-astronomy.de/temp5/5189colourgut.jpg Stefan |

It must be bright with only 30 second RGB images. See you are using your old camera. 8300 might be too small pixel for that scope. Seeing wasn't up to going full out without the reducer? Don't know the sky down there. At 30 seconds was there any need to guide? I rarely guide 10 minutes. Weather has finally cleared here Clear Sky Chart is saying very good seeing. So I hope to try for a tiny planetary at -10 tonight. Will need 0.5" pixels. Very hot here so won't be able to cool like I'd like. Hot weather gives lousy transparency low but great seeing. Still, like this one and the "bug" it is bright so hope I can pull it through the gunk. Just added up my backlog. About 150 yet to process. Yikes.

Rick,
I used the SXV-H9 because I damaged the Atik 383 the night before... Quite a bad timing to do that halfway through a Namibia visit... I was very glad that I had been paranoic enough to take the old SXV-H9 with me, otherwise I would have had to use a DSLR for the rest of the week... Image scale is 0,57 arcseconds/pixel even with the reducer, so it didn't seem too tempting for me to go without the reducer. I would have needed subarcsecond seeing to make that work. And the FOV was already very small with the reducer in place. Stefan "Rick Johnson" schrieb im Newsbeitrag ster.com...

I don't think that camera likes Namibia. Didn't it go bad just before
last year's trip? I hope it won't be months back at the shop getting fixed. Saw on a forum where someone took the SBIG 8300 camera there a couple weeks ago and had the shutter go bad the first night. I don't think that area of the world likes the 8300 chip! I hadn't realized the SXV-H9's pixel size was nearly as small as the 8300. I was thinking it more my size. Getting to be too many out there to keep track of them all. Rick On 7/8/2011 2:11 PM, Stefan Lilge wrote: Rick, I used the SXV-H9 because I damaged the Atik 383 the night before...
