Just 5 hours 30 mins of luminance, but the seeing was amazing, at 1.5 sec arc. We've added colour data from way back in 2015.
(The luminance data are so much better than our 2015 data that we just put the old stuff in the round filing cabinet).
The thumbnail is a crop.
BIG ONE HERE
This galaxy is so close to us, and so big on the sky, one gets the feeling that one is seeing individual stars in it. Perhaps the things that look like stars (by the tens of thousands) are actually star forming regions - each dot being hundreds of stars - but there seem to be implausibly many of them for that. Apart from a slight difference of opinion over colour (we think it should be warmer, Lee thinks it should be bluer), our image is almost pixel-by-pixel the same as Lee's recent image: we confirm each other's work, and the dots, whatever they be, are not artifact or noise.
There are very many far-distant galaxies in the background, a couple of which have long tidal tails.
Lum: 5h30 in 30 min subs. RGB: 4h per channel in 1 hr subs, 2x2 binned.
FLI PL16803 on 20 inch PlaneWave. All robotics (electronics, firmware, software), acquisition and processing software designed built written in house by us. Like a dog climbing a ladder blindfolded, the miracle is not that it works well, but that it works at all.
Expecting 40 to 75 mm of rain over the next few days, so this will be it for this month.
Best,
Mike and Trish
