SCT laser collimators

I've used this many times over the years on C8's and a C11. IMO, it's good for checking your alignment, but I always seemed to tweak the collimation on a star anyway. I also found the best way to get the initial alignment was to collimate the SCT at high power (>300X) on a star and then see where the beam returns on the face of the collimator, marking that spot with the white dot.

At the end of the day, I think collimating to a real star is the best and so only use my laser to check alignment on my newt.

Who is who

Mike,

Actually, I'm not quite sure myself who is who, which is which, and whom is whom. I was just giving you some old fashioned geegawing and all in fun.

Why so many AT1010's for sale?

Posted By Randy Roy

I replaced mine with a Stellarvue 85S APO. Outstanding scope!

Sit on what ?

Posted By Randy Roy

I have the Starbound chair and use it with my N8GPS and 85mm APO. For the 16" Starmaster, I mostly stand.

It's a little pricey, but works great.

Who Invented the "Newtonian Reflecting" Telescope?

Posted By Randy Roy

I thought Rick Singmaster invented the Newtonian. Perhaps he just perfected it.

Teegul(Lapides) Mounting Capacity?

Posted By Randy Roy

Hi Paul,

I've had one of these mounts a couple of months now and really like it with my 85mm F6.9 APO. In fact, I think it is by far the most elegant alt az solution for a small scope by a big margin. That said, I'm quite confident that it would handle a 4" APO (say up to F8 or so) with no sweat, but I would be very leery of putting more than that on it. I'm not sure what the weight capacity is, but with scope, 2" diagonal, clamshell, 26mm Nagler and the A-P dovetail plate, I'm hitting up around 11 lbs with no flexure, problems with the clutches, balance, etc.

Hope this helps.

Obsession or Starmaster

I would love to have a house-full of oak furniture of the quality of Starmaster scopes :>).

Televue SCT adaptor. Is it firm and tight?

Posted By Randy Roy

Vincent,

I find the "newer" TV adapter (compression ring style) to be even better at clamping down than the screw on type of diagonal. What I mean is the screw on type can have a tendency, if you don't tighten it enough, to unscrew if the OTA is tilted down toward the left and if you have a heavy enough load. Of course this doesn't happen with an alt-az, but does with a GEM. I highly recommend either the Televue or the Astro-Physics model. I use the Televue "Short" adapter with a 2" "Short" Everbright. Clearance is never a problem for me on my N8GPS.
