Still waiting for a clear night.

So far I haven't be able to use the scope yet. Been cloudy just about every night. The few nights it was clear I was busy. I do love how it looks and feels! Cant wait to get it on the mount and put it to work.

New telescop - new hope

Actually i was kind of het used to my Newtonian telescope, but still it was a real pain, because of collimation. And because i live in a light poluted city, I stiil need to go somewhere else to do astrophotography. And this is when this refractor came in handy and when i got a very good data, at last, which wasn't that painful as with a Newtonian telescope. So I'm very happy about this purchase, so i could do a really good photos with this scope. I live in Russia, so sometimes delievery time is really long, but with UPS it took around 2 week to deliever (which about 1 week were taken by the customs)
