Chris,
Fantastic tips there!
I am interested in your reply re aperture. This might sound a little silly

as I don't know if depth of field applies effectively for say a F4 SN OTA but can this be done? Ie in prime focus where the camera is t coupled to the OTA, can you "stop down" the OTA to achieve this?? Eg I have a 8"SN F4 scope - would adding an aperture mask on the front achieve any real depth of field?? Very interesting as my moon photos are just like you describe - void of any real sensation of a 3D object and slightly out of focus in areas but in focus elsewhere

.
I would love to hear your opinion on this as us beginners sometimes struggle even with the basics. I'll give it go anyway see what happens - that's part of the fun of this hobby.
Cheers,
Darrin...
