Since the stock camera is not cooled, What is the maximum practical exposure time without getting swamped time dark current? Other than Envisage & Maxim, What other image acquisition software is there that works with a DSI AND is in FITS format? -------------------- Carl My lousy skies at Hawkeye Observatory Post Extras:       yock1960 professor emeritus Reged: 06/22/08 Posts: 980 Loc: SW Ohio, USA Re: DSI Exposure time [Re: Galaxyhunter]       #3392527 - 10/16/09 08:20 AM Edit   Reply   Quote Quick Reply   What kind of ambient temps will he be imaging under? I don't have the -I. With my -II non Pro, I find that once the reported CCD temperature starts getting into the higher 20's, things start looking worse. Apart from that, I regularly go 8 minutes.

He will be using it during the fall. I don't think he's real eager to be out in the middle of Winter. -------------------- Carl My lousy skies at Hawkeye Observatory Post Extras:       Mobius1 professor emeritus Reged: 08/28/05 Posts: 700 Loc: Madison, WI / Gurnee, IL Re: DSI Exposure time [Re: Galaxyhunter]       #3398377 - 10/19/09 04:05 PM Edit   Reply   Quote Quick Reply   Even 20C or so kills me, I tend to wait until around 15C (and it's been cool enough for much less than that lately). I usually don't image more than 3 minutes anyways due to tracking issues. -------------------- Martin William Optics 66SD Orion 100ED Orion 120-ST EQ PST-Ha Celestron CGE 1100 Canon Rebel XSI with Astronomik filters DSI-IIC Homemade spectroscope in progress...
