Wow, do I have a lot to learn! I'll try and repeat your process step by step. Thanks Luftfluss, what an advert for the forum you are!
Aww shucks My post-processing abilities are very limited, but I do think PP is underrated as a way to improve one's photos. I have to be wary, though, because sometimes I get lost while trying to "fix" something and I wind up with an unnatural-looking result.

The greatest invention added to television = the mute button on a remote

The best feature of a PP program = the "restore" button

Very helpful again, thanks.

A quick review of the samples in the gallery suggests that I should probably be using half a stop less of aperture to buy back a bit of shutter speed and dynamic range (from lower ISO).

The sharpness of the lichen suggests that I'm there or thereabouts for focus adjustment and stability (not that I can't get better). Time to be bolder on subject isolation; there are some amazing photos wide open.

A few more - the moonshot a few posts back was one - from yesterday's ramble with the Tamron Adaptall-2 SP 400mm f/4 LD IF - 65B + Pentax Rear Converter-A 2x-L

This was after I cropped away about 70% of the frame

Again with 2m focal length


I will try to identify a small object on the moon to calculate the resolution of my system. I would calculate: The moon has a diameter of 3476km, on the picture I have 3770 Pixel for the moon diameter, which could be 1km per pixel on the moon. Now I have to detect a crater or something else of ~2km diameter in the south of the moon (where the shaddow is present).

Can anybody help?

I believe that you have a serious problem. You have to identify a 2 pixel x 2 pixel area. I don't think it can be done, frankly.

Let me start with Schickard R (Schickard (Mondkrater) ? Wikipedia) from my last picture - here 2x magnified. Schickard R is about 5km large ==> see here
Is is also visible in the picture from three days ago - which means it is not an artefact.

Went and shot some sky carp this weekend because they are out in force again. This is probably my favorite picture of one. Sigma 300mm f/4 APO Macro with about a 50% crop.
