We have had some really super clear nights - unfortunately - I have been shooting football Fri and Sat and process those pics. But tonight - I will give this beast a go. I am still working on NGC 2403 and will add some photos from this 12 incher to see what happens.
We will see if size matters!
Before you point this out...I realize this guidescope will not do much good...I am working on how to mount the Starshoot 400 short tube guide scope.

Nice setup Ed nice and clean. Will the bracket mount to identical holes
as the finderscope on the other side of the main scope???
That will be a very cool shot Ed you also get a Nebula in the deal too.

Nice set up, this is the one your son gave you?

No....I will have to do a little engineering for the short tube. I will not have time today to fiddle with it so I will see what happens with the 162mm mounted now.

Nice light bucket Ed!
If all things are copacetic, it should give you a lot.
That guide scope looks to be one of Orion's 50mm with an Orion SSAG camera on it.
Orion Magnificent Mini Deluxe AutoGuider PackageI wouldn't be to fast to discount what the little appearing guide scope can achieve. The same thing is in use by several professional observatories.
And on my set up, one of them is the most reliable and accurate device I have. Never a lick of trouble.
After all, a guide scope has one job. To catch
a single star and stay locked onto it till the Sun comes up.
(Or in the case of last night here, a damned cloud cover blows in...)
But, of course, it is your toy to work with.
That's one nice scope your son gave you. I don't know enough about that mount but the counter weights seem awfully close together.
My 11" SCT is a beast as well and the field of view is pretty tight but my optics are decent. I just don't use it very much.
I need to figure out guiding and I've been guilty of a bad case of lazy.
Look forward to seeing what it pulls.

Hi Jim just wondering what you meant by the counter weights being too close together or to close to the scope???

The mount was balanced - the weights are fine...guiding was above average considering I was using a 166 mm guide scope on a 3000mm OTA.

I'm wondering, Ed. What is Hoyle on the Big Bertha scopes like that for guiding?
Is there some rule of thumb? (Not like I will ever be in those shoes, just one-der-ring.)
(For example, my 55 mm guide scope is good up to 1500 mm optics. But what does one do for double that?)

110 silly...
How about two 55's, side by side?
Actually I think for the 11" scope my Orion 70mm guidescope and the Orion StarShoot Autoguider Camera would be a good pick.

Important note from the article:
"Use a guide scope at least 1/3 the focal length of the imaging scope, or longer".
My 9.25" 2350mm fl = 783mm fl and I use a 279mm fl guidescope.
It can guide it pretty well for what I can afford and the weight issue of a 90mm plus dovetail bar.

That was my concern when I initially kickstarted the 12 inch 3000 plus vixen. The guide scope I am using is 166mm. I have a 400mm short tube but I need to rig it to work....I will come to grips with that later. I am so "not impressed" with the vixen and doubt I will spend to much time dick'n around with it. I add another 90 shots to the 82 I kept from the night before. I haven't worked on the image yet but the subs just see lacking to me. My son (fool and money soon part) paid close to 4,000 american for it...said it was on sale because they were dis-continuing it...that it originally sold for over 5,000.
