NGC 7006 NGC 7006

NGC 7006 is approximately 135,000 light years away (other sources say it is as far as 180,000 light years away). It "lives" about the Milky Way's galactic halo. I'm not thrilled with the image but conditions were not ideal. What I find interesting are the small blobs in the field - those are distant galaxies. Oh, Universe, I behold thee!.

14" Astro-Tech Ritchey Chretien

2018.04.06 Laser Collimation

Thank you, Howie Glatter.  I purchased a 2" laser collimator from Starlight Instruments and rather quickly I was able to collimate the secondary and primary mirrors.  The stars look pretty good now. More to come..

2018.3.26 - Collimate What?

My new Astro-Tech 14" RC looks nice but I have yet to tame the beast...

My previous OTA was a 14" Meade LX850, a fine OTA. But in the Paramount documentation (the mount is a Paramount MX+) I read that with a fixed mirror OTA, the Protrack system can provide very precise, unguided tracking. With an SCT and the mirror flop issue, this is not possible, according to the Bisque documentation.

So I decided to sell the LX850 and get the ATRC14. My first "complaint" about the ATRC14 is that there is virtually no documentation about the scope, particularly concerning collimation. I'm new to RC's so this can be a challenge when you consider that you can collimate three assemblies - focuser, secondary mirror, and primary mirror.

Despite a couple of emails to Astro-Tech asking for guidance or documentation, I got no answers so I've given up (and also given up on future purchases from Astro-Tech).

That said, OptCorp has posted a somewhat helpful video on youtube about collimating a 14" GSO RC that was helpful, though I wish there were more details...
