Oh yeah! The drizzle tool works great, although it really put quite a load on my pc. It took almost an hour to get through BBP (I was calibrating with new flats, that wouldn't have help with duration) |
Thanks Rod. I selected an ROI and it crunched through 35 subs in no time - very impressed.

Hi Greg. This is with a 250 f4 Skywatcher - I retired the 200 GSO and now have the luxury of a CF scope
- which is a major plus at f4. At this site, I have always been seeing limited, even with the old 200mm scope - an 8 inch scope will resolve just as well as a 20 inch under these conditions. I have the sampling at 0.9 arc sec, but have occasionally had seeing below 2 arcsec - ie it's undersampled. Drizzle looks like being a great way to take advantage of this (very welcome) problem.

Yes the drizzle algorithm is great, I've played with it on some data I'm currently collecting and it looks very promising. |
Thanks Rolf. Drizzle was fairly painless in PI, but in combination with deconvolution, generated some messy artefacts on the brightest stars - left them in for info, but it is only a cosmetic issue that will probably be fairly easy to fix with careful masking.
