Wow this is way cheaper than what I paid for the QSI. The sensor is superb there is no doubt of that.

I currently take images at -20C and it does this at 58% of capacity. Another month it might struggle a little but water cooling will also help.

Congratulations on the purchase.

Probably not... the sensor is burried 17mm deep in the camera body.. that alone is probably too much distance..

It is an 8.3mp sensor though, and you may get away with it if you've got a slow optical system... for something fast, I dare say 1.25" filters will vignette fairly heavily.. but even if you crop it out, you'll be left with at least 6mp worth of image... Just depends on how you want to do things I guess... I wouldnt use 1.25" filters with it.. thats just me..

The QSIs filter wheel is built in, real close to the chip, so it gets away with 1.25" filters.

SBIGs site mentions the "possibilty" of useing a 1.25" filter wheel, but only with long FLs, F10 I guess.

exactly.. their filter wheel is less than 10mm from the sensor, and even QSI say with very fast optics it may vignette...

Yay, SBIG has finally seen the light. I doubt they will be able to produce these camera's fast enough to keep the mobs happy . The 1.25" filters are too small for the chip (28mm diag) but the 50mm filters leave it swimming (depends on how close you can get them to the chip I guess) but 36mm would probably do it. Stepper driven filter wheels and 2" filters are expensive but you can soften the pain by buying from the US unless ATS has another trick up it's sleeve . Astronomic 2" mounted type II LRGB sets are going for a song at OPT.

Luckily for me Mark, I'd already bought an FLI 2-5 filter wheel for my Orion, and Astrodon Narrowband filters... Whilst these were overkill for the Orion camera, I knew I wanted to do narrowband imaging, and I knew eventually I'd get a large sensor monochrome camera... The camera just came sooner rather than later... Normally I would have been more hesitant on new gear, but its an SBIG... I trust they've got everything right!

Never a doubt on the SBIG quality Alex just the smack in the gob you got every time you priced one . Hmmm I wonder if Mr Ward is thinking of putting a GSO RC 8" with G8G and ST8300 package together. That could really get the punters drooling so to speak. Perhaps he could throw in an WO ZS 66 to use a s a guide scope as well . I see bintel have reduced the price of a G8G down to 3.7K and the G11G is down to 4.8K ......

Yep.. This was the first time I'd ever looked at the price of an SBIG camera and thought "Wow.. thats CHEAP!!!" just so happens its cheap and its carrying the exact sensor I've been wanting.. Right in time for Xmas too!!

Yeah that would make a serious bundle.. G11, WO ZS66, GSO 8"RC, SBIG ST8300 and SBIG STV guider.. would be an insane kit!

Alex, plugged the GSO 8" and 8300 into CCD calculator, gives 0.7 arc sec/pix image scale, and a very handy FOV, sweet ;-).

Yep.. It would be a winning combo thats for sure.. Paul Haese has the KAF8300 based QSI camera in his 8" RC and the images he's getting show very nice resolution and a great fov.. .

Must say its all just a little bit too exciting.. I think I need a cigarette and a cup of coffee to chill me out a bit!

It will be the 10"GSO RC for me if it ever turns up along with the ED127 sensational.

Delivery is expected next month Dave...

http://www.atscope.com.au/sbig/ST8300.htm <- That is the information directly from the SBIG website.. It was enough to sell me.

This is on ATS -> http://www.atscope.com.au/sbig/ST8300.htm

I've seen the exact same blurb on a couple of sites so it's probably originally from sbig.
