It's that, or see what they go for and put the funds into an ASI of some kind... But I do kind of hanker after keeping at least one of them - probably keep the 2-1 and sell the 2-0. Sensitivity a plus at that pixel size...

And SharpCap worked - thanks for the suggestion. Considering their fate now that I know they work.

Thanks - I'll try SharpCap - at least it would let me power up and try out again.

Hello all... I'm looking at two Lumenera cameras that I've had for at least 10 years. I got really good use out of them as planetary cameras a while back, but planetary imaging had to take a back seat for a few years, and now trying to get back into it. But the Lumeneras best days may be behind them - apart from their basic spec, it seems Lucam Recorder is obsolete and other capture software (I've got FireCapture) don't seem to support them.
I think they are probably destined for sale, but before I list them, is anyone still using these, and if so, how/with what? Their near relatives still seem to be used for microscopy, so I'm wondering what I should do with them.
Any suggestions?

Lunar Reconnaissance Orbiter imaged the various Apollo sites and artifacts (including an impact site from one of the Saturn 5 third stages impacted onto the Moon as a seismic experiment).

But that, of course was at a couple of hundred miles or less, not 250 000...

Celestron 9.25" or 11" SCT OTA?
in Discussions - Scopes / Whole setups

A factor to bear in mind is I believe that the primary mirror in the C9.25 is figured at f/2.5, as opposed to f/2 for all the other Celestron SCTs (8, 11, 14). Don't know why they did that, but it makes the mirror figure just that little bit more forgiving/easier to make and consequently yielding better images. That assumes that you don't ever truly reach 'diffraction limited' seeing conditions. In that case, aperture wins - not just for light gathering power but in this case because the resolving power of the bigger aperture at Dawes limit is better.
