I am having real problems with seeing small bright objects. The mooms of Jupiter have two " tails" as do stars, ie they are not pin points of light. I have collimated till I have run out of ideas, all the rings match up and the star test gives beautiful concentric circles.
I can easily go to 400x on the moon but the cloud bands in Jupiter at anything over 80x have no detail, I used to be able to see some of the festoony bits once.
Are my eyes stuffing up??
Any ideas please.
