Only a 3-frame stack but I struck lucky:

Dd you use a filter for that?

No, I used 1/1600 second exposure and ISO 400.

that explains why its so grainy then

The max ISO I use on the moon is 200, most of the time you can get away with 100, this keeps the grain down and makes for better subs. OK you may get more atmospheric disturbance because the exposure time has to go up but it is still sub 1/100 of a second depending on the phase plus that is where multiple subs and Registax comes in.

I always stick to 200 too and aim for at least 42 subs. Gives a lot smoother image from which to start polishing in post processing. Sadly I can only get the moon from home after around 70%

I can't get Registax to work on full disc lunar images. I'll try lower ISO and longer exposures, as some of you have suggested. I use Microsoft ICE to stack my full disc images, as Registax runs out of memory.

I went with ISO 100 and 1/400 second exposure and stacked 200 images. It seems a bit better:

That is a big improvement. Focus looks a little off though to me?
