I will upload a performance brief on the U8300 versus the ML8300 and QSI 8300...

I have that at home

the apogee is clearly much better than SBIG or QSI.. no comparison. But it falls short of the FLI in a number of areas... Let me get into it once I upload teh performance brief... Trouble is that I need to revise it...

the key things I did not like about the apogee U8300:
1) 30 minutes to cool down or to warm up. Power failure costs one hour to let it warm up and then cool down.; Dumb dumb dumb and all based on a lie in my opinion
2) poorly designed cooling system: air stagnates in the heatsinks because they obviously don't understand heat transfer. I think a sophomore mechanical engineering student could do way better.
3) slow downloads: same as SBIG but way faster than QSI.. still takes a good 8-9 seconds vs 2.3 seconds.
4) poor implementation of RBI light flood: no user controllable parameters.

Richard, thanks for the info, I value your opinion. Marc

Richard how you like apogee?

Different people run their businesses differently. I don't hang up on my customers, but Mr. Lane can tell you a story about how he received that treatment from M. Barber of SBIG...

Big companies play with everyone. I never leak about my dealings until they do, because then its a significant thig

Aplegen has either claimed or hinted that Roche is a customer. That might only mean that they bought a couple of eval cameras and have no plans to buy more.. who knows what the truth really is when dealing with those guys.

personally I expect most of aplegen/sbig's sales to remain in the astronomy market bought largely by their cult-like followers... only a cult mentality explains it in my opinion because the cost/benefit ratio certainly doesn't...

I'm in industry, in my opinion with life tech, Roche, and illumina already saturating the market no other company has a role unless they have an accuracy increase which anything relating to a ccd won't cater to. So sbig marriage to applera isn't going to work, at least for genomic. That would be my take with limited I formation.

You may be right Charlie. I saw that Hugh Martin of Pac Bio was replaced by another CEO. Not sure if the opportunity that Aplegen/SBIG sold to the AVI-TECH people in S'pore is even feasible at this point....

Sbig will be cut loose from their parent company, sold to Meade or something, or perish. I'm going fli.
Comment by Richard Crisp on January 11, 2012 at 2:18pm

a lot of people buy sbig and qsi cameras too... that says nothing about the quality or the cost/benefit ratio...

I don't buy products from that vendor...I think the cost/benefit ratio is out of whack quite frankly.
