Absolutely superb! You keep this up and we'll never get back to the Moon.

Pricing question??

Posted By Louis Busby

Between $825 and $1000. Higher as they become rarer.

refractor disassembly

Try shaking the screw out of the focuser end. Surely collimation will be affected if you remove the objective. If you can't get the screw out of the focuser end, mark the position of the objective cell on the OTA so you can position it back in exactly the same place.

Jason,

That is an approach image. Continue to the next page of the website to see a flyby image of the previously unseen side of Mercury.

I've started a small collection as well. Here's My center piece -- a nice example of a Campo, 20 pounder.

M51 - b/w bare bones wide field

Posted By Louis Busby

Tom,

That's a very nice image and one that I prefer over many RGB M51 images I've seen here. I've always considered monochrome images to be "more scientific" than tricolors. Certainly, the RGB images are pretty to look at, but I think mono kinda takes me back to early film, science only, astrophotography before astronomers had the wonderful CCD and digital tools we have today. It's kinda nostalgic in a way.

I was a fine art photographer for many years and I always shot black and white film. So, in essence I still consider monochrome as the "purist" approach. Such is the case here with your M51. Keep up the great work.

Simple M81-82

I like that one very much. Lots of faint fuzzies in the background. I'm gonna get one of those STL11Ks some day.
