Oversampled 50mp Mosaic with 140mm Refractor - April 29, 2023 72% Waxing

[WestCoastCannuck]

My C11 did not settle in time,  but my 140mm refractor came through!

140mm F7 @ F13.3,   2.4um pixels,  520nm filter, best 600 of 2000 frames,  4 panels

 

Clear skies to you!

Excellent. That's one of the best Moon images I've seen.  😊 What's the bandwidth of the 520nm filter and the exposure used. I've used a Baader 10nm solar continuum filter at 540nm for the Moon with good results, FLT98 and 2x Powermate, but it doesn't quite match yours. Your extra 40mm aperture would make a significant difference I imagine. 🙂

Thanks much Alan for your kind words.

Off the top of my head, I don't remember the range of the filter, but its the Baader green ccd filter from the LRGB set.   

A 140 refractor indeed does capture much more than a 100!  .  I started with a 100.... Then a 120.  This is my last one.  I simply can't afford significantly bigger or believe me it would probably happen.  Lol

That's a nice sharp image. Excellent work !

The joys of getting larger scopes to settle. Good to have a quality refractor as a backup. Nice result Mike. Your usual high standards

[ONIKKINEN]

Really sharp! Not sure i would call this oversampled no matter what the theory says. My eyes seem to like it very much!

Very nice and sharp image. Like the very natural look, crisp, but not over-sharpened at all

Are several of you confusing oversampling with over-sharpening?

Yeah...   wish it had vents for fans.  Sadly not.  And thanks Neil - in spite of some tracking issues it came out well.  (just more panels than usual)

Thanks Onikkenen!  As you say...  its only over sampled by the math - and not all THAT much.   I actually did the last sharpening at F22.4.....  then reduced back to what I hoped was a sweet spot.

Thanks Michael!   Like many of us,  I struggle sometimes to find the balance in sharpening.  haha.   We SO want to show all the detail we can....  but there is always a price.  haha
