After some trial and error I'm getting some very good guiding results with PHD2 now. 60mm guidescope and ASI290MM mini camera. The M42 image taken late March was 12 x 15 second exposures taken manually with my dslr / C8 and a stopwatch. Stacked in DSS and played with a bit in GIMP. On the night I couldn't get APT to register the camera - turned out to be the mini USB cable (although later trials point to the socket in the camera being a bit loose too).
Bought an iOPTRON iPOLAR that arrived on Friday and had a play with that which has resulted in near perfect polar alignment. 2 star alignment and an additional 2 calibration stars on my Advanced GT mount means I'm getting very accurate GOTOs now and PHD2 (through the ST4 port on the ASI camera) seems to be guiding very well. Last night after more cable faffing I managed to get everything working together to the point where I felt confident enough to leave it running by itself for an hour and a half (45 minutes of 180 second exposures plus 3 minutes each exposure to save the file - I've since found out I shouldn't have noise reduction switched on in the camera - DOH!) so M51 is 15 x 180 second @ ISO 800 lights and 5 x 180 second darks. A little manipulation in GIMP and I think it's come out very well. Obviously still have a lot to learn and I'm going to have to start taking much longer exposures but I'm quite pleased with these 2 pictures.
No extraordinary images for this lunation, because of the turbulence and the use of infrared filters.
Here are some images of the 24th, I am working on those of the 25th which will be of the same style.

Just a quick enquiry ... was strolling the lunar surface on Iroc and bumped into this area of florescence on the lunar surface.
Any thoughts anyone? (Co-ordinates at bottom of screenshot if you want to get better definition from original website).
Was struggling to see clear heavy impact crater that would account for the wide spread of surface debris?
Didn't think it was image flare - not expert on that so could be wrong - but noticed on RHS there appears to be traces of surface debris scatter?
It almost seems like someone threw a very low velocity ‘flour bomb’ at the surface of the Moon?🤨
Have there been mineral studies done on these areas of exceptional lunar florescence? ... I tapped the phrase into SGL’s Search ... but surprisingly it came up with ‘no results’??
