Yes, I brought it up for what the cab driver said; didn't mean anything about the human shields; just used it for the context.

Guiding short focus telescopes

Posted By Andrew Riehl

even at 400mm, you will absolutely want to guide it. I had a 300mm telephoto that I used a guidescope on. The Tak mount is very smooth; but why take the chance?

Very nice. Is this a single exposure or a stack? If a single, your seeing looks very good...Keep up the good work.

Well, I will say that registar is worth every penny. I use it almost exclusively for my color combining as well.

What mirror material is this ?

Posted By Andrew Riehl

I dunno, my first thought may be possibly ceramic? I know a few scope makers are using ceramic mirrors, but don't know what they look like uncoated.

Given the current selections available now, it's even harder to beat Kodak E200 (elitechrome)

Fixed and portable pier

I believe you may be referring to Particle Wave Technologies (an Astromart sponsor). They have a link on the astromart home page, here it is to save you a step. Is this what you were thinking of?
