Agena 1.25" Side View Newtonian Laser Collimator with 2" Adapter
Review
Works as advertised. Did my scope in short amount of time. Easy to use. Gave it four stars because its not perfect, should include detailed instructions for collimation, but it is good.

Cleaned my CPC 800 corrector plate and mirror, so a complete removal. Put the corrector plate back on and it was completely out of collimation of course. Installed Bob's Knobs, and was collimated in just a few minutes. Worked so well I just orde...

Farpoint Bahtinov Focus Mask for DSLR Camera Lens w/ 52mm Filter Thread # FP438
Works Very Well
The mask works as advertised and helps me to focus when using my Canon T2i and 135mm lens. With the smaller FL lens, I use a higher than normal ISO (3200) and have the aperture wide open (F/2.8) and focus on a bright star. I don't bother shootin...

HoTech 1.25" SCA Laser Collimator - Crosshair
Great product.
Works as advertised. I own a cheaper laser collimator that would wiggle in the barrel. This Hotech collimator holds nice and firm giving a more accurate alignment. With the laser crosshair, aligning the mirrors is much easier. Worth the extra money t...

GSO 1.25" Newtonian Deluxe Laser Collimator III
Works Well
Very economical tool that worked for collimating my Newtonian scope. Knowing what I know now I would recommend spending more for one that has variable brightness for the laser.

HoTech 2" & 1.25" SCA Laser Collimator
Easy to use - instruction are pretty clear. Agena Astro Products was great in getting it to me in 3 days (regular postage). Looks like I have a main source for my astronomy needs!

Bob's Knobs for Vixen R200SS Primary # R200pri
So simple, so essential !
The two simple sets of easy to handle knobs are an essential tool for aligning both the secondary and the primary mirrors of the very fast (f/4) Vixen R200SS. The knobs can be easily turned by hand, which is a real boon by night and/or during an obse...

Farpoint Bahtinov Focus Mask for Celestron 11" SCT # FP412
Much needed accessory
After years of astrophotography, I got around to use one of these instead of using software to focus, and the results have been way cooler than I excepted.

Batinov Disc for a Celestron NexStar 8SE telescope
As soon as it arrived I was able to place it on the front of the telescope and begin to focus it. Focusing is very easy and if you line up the third line in the middle it is next to perfect.

Hubble Optics 5-Star Artificial Star for Testing and Collimating Telescopes

Purchased this to collimate my C8 edgehd and I'm very happy with it. Makes collimation much easier than having to deal with a real star (don't have to worry about tracking and atmospheric turbulence). My only complain is that I wish the bod...
