Very nice work Krisjan. Looks like it could be a production model from Astro Physics! How does it perform? Have you given it a thorough test drive yet? Is that a custom made lens? Tell us more.

That is a Nice scope you have, kriskarl.
What is that sticking out from the focuser? A fine focus knob?

K. Just looked through your site(and what a great site you have). I see that it is a motorized focuser. Very Nice.

Thanks guys
This lens is 127mm F 7.5 3 element. and is in counter cell. this was the only lens in this size that Istar had. it is verry sharp and good colorcorection. The focuser is from Crawmach focuser motor from Cercis tube rings from Crawmach.
When I made this telescope, I wanted to everything at best. I will later build a bigger scope, so this was good testdrive.

Nice job Kristjan. Very professional. Do you mind if we post a couple pictures on the Istar web site? Iceland sounds very interesting. You'll have to tell us a little about your observing. Now if you could just get those volcanoes under control

Thanks Mike Feel free to use any pic. from me. observing in Iceland is from sep.-apr other month is ligth all nigth. My main interrest is taking picture of the star,nebula and galaxy. But here is a lot of light pollution so it is a challenge to get good picture, I use a ligth pollution filter and a modifide canon 30D. I have a Losmandy G-11 Gemin and my setup is in a Dome that I build in my backyard.

Welcome to the Istar club!
Wow! great job and I can't wait to read more about that lens! Here we only know of Iceland from your volcanos, I hope they are not as bothersome to you...
Please post some Astro photos, I'd love to see them...
