Good to hear that your scopes collimation seems good atm and will leave it alone for now , use and enjoy.

That is an awesome shot there Jeff, something to aspire to. I'm hoping to get a chance over the next week to do a bit more playing around with the new eye pieces, and break out the Barlow. If I'm reading the data right from Mateoblue it should be reasonably good weather in the next few days, with Jupiter and Saturn in relatively good positions.
