I got out with the scope for the first time in a LONG time. I have had it out for a few minutes at a time only a couple of times this year. I am running rather low on sleep so I still was only out for an hour or so, but even so it was good to get out.
I finally got around to reading about this mysterious "barlowed laser" collimation method, and used it this evening; it's brilliant. Dropping the laser collimator into a barlow lens totally eliminates type 2 misalignment from being a factor in the final collimation. It made me smile when I saw it working.
So anyway I saw some really good pinpoint faint stars that popped into being only at critical focus, which to me indicates that the collimation is pretty much spot on.
Anyway, going to start a couple of video encode jobs and get off to bed.
