Its a bit rough but my first attempt at this resolution. will need good seeing to be better. But its work in progress

Not a lover of the Moon but that is superb for a WiP.

I think that this is as good as it gets. F/12.6 is a bit high for 2.4µm pixel size. At 510nm optimum F/ratio is about f/9.4.

9.4 / 12.6 = ~0.75 or 75%

If you take your image and down sample it to 75% of posted size - it is very very sharp. For example - this is piece of it resampled:

Or this:

I'd say that it is as good as it gets.

Yeah i should get a 1.5x barlow. Sometimes its just worth using what i got though.

That's superb Neil, what did you use to build the mosaic?

Hi Geoff thanks I used microsoft ICE. Think i can do better. But its a pig building it. and recording it. I Should go on the hunt for a good 1.5x Barlow. Worth ironing out problems

Amazing! On full zoom i thought i was flying over the moon. Great work!

Not sure how much of a budget do you have for barlow, but I think Baader VIP would be worth considering. It is modular barlow that is of exceptional quality - and is made for imaging (well - VIP stands for Visual and Photo work). You can vary magnification factor by changing distance.

Glad you found it interesting Kon. It is fun. Moving around the lunar surface. A good bandwith here. Hard to show it full size in most places

Thanks Neil and yes, it's definitely a pig to do. I tried the nearly full moon twice, but missed sections in both attempts. The 2nd try was better than the first (see https://www.astrobin.com/full/369059/0/?nc=collection&nce=1697, but I haven't tried it again....

Stunning Neil!!

Well done, and thanks for sharing your hard work..

Not sure how you mapped. But i found making sure the movements of the scope are straight, up down left right. Helps the process. By rotating the camera so the movement is exactly straight. Will help minimize a problem. Drift is another issue. you may see the area you want correctly. Start recording. But if the pane drifts out of alignment. When stacking the drift will lose some area you need. But yeah been there done that too Geoff

[neil phillips]

Many thanks Omyd and Steve

[Peter_D]

Absolutely fantastic image! Not sure if you post on CN too but it deserves to be seen far and wide. Well done again 👍

[powerlord]

Cheers for the comments.   I actually prefer the prime focus version on the other post. 28th sept. Wanted to bring this to life to see what such a hi res shot would look like. I had problems with it i am not happy about. But as i said its my first attempt. In time i will do better i think. Work in progress thanks for all the interest

Now reduced to 75% and looking a bit more uniform
