20260320 Jupiter and M81/M82/NGC3077/NGC2076

Setup the S30 for mosaic around M81, M82, NGC3077 and NGC2076.

1:37 hr of signal acquired.


One with latest AI denoise another is raw stacked.

Trying out Jupiter with my 8" SCT, collimation was off after quite some time.  

Some videos were taken at prime focus, I didn't take any after inserting the barlows.  Collimation was pretty off.

(result pending)

Focusing with the short pier is no fun at all, centering the Jupiter was not too difficult with the bigger sensor of the 533mc but I don't think it's much fun.  I am one more step closer to sell it, for visual observation a dobsonian might be better.  I don't quite like planet imaging any more.  Long focal length deep sky would require a better mount which I won't probably want.  Time to downsize?

20260321 Followup

The collimation screws were too long, it should be 8mm but mine were 12mm, maybe that's why they couldn't hold the collimation well enough.  Order has been placed to get 10mm collimation screws since I could get exactly 8mm.  The new one has thinner thumb holder was shorter, the lens cap might be placed on after changing?

On checking my blog, I was considering adapting the NGF-CM to the ZWO EAF.  It's well worth further exploration.
