Crisp!

Excellent details considering it was captured at day light. The IR filter has really made a difference.

Thank's Kon, beats staying up late! and keeps the imaging going during the short summer nights. 

Your efforts on Saturn have been outstanding! I can't get it yet as a corner of the house is in the way, I need to get an ASiair Plus so I can get the scope further away, too many long cables going on right now. 

So watch out, I will be on it soon!  😉

I agree, all these late nights or I should say, mornings, are having their toll BUT how often do we get so many days of dry weather. I am looking forward to your planetary images.

That is an excellent image!

Any idea the vertical height of that wall?

I envy those who will eventually colonize the Moon. The sights they will get to behold.

They might not admit it but I'm certain every one will take a moment to just stand there and go, WOW!
