Forum Rules. What's New? Page 1 of 2 1 2 Last Jump to page: Results 1 to 10 of Add Thread to del. All-- I got REAL tired of crawling around on the ground and bending my 61 year old back and neck at insane angles trying to look through my finder scope , which is best mounted on my guide scope. This puts the finder scope eye piece back even with the rear of the OTA.
Astro-Tech's 10x50, illuminated, correct image finder scope was the answer. It has a right angle diagonal, removable eye piece, and removable illuminator. The larger diameter 62mm 10x50 scope will not fit in the stock AT8IN finder scope ring. A note about the base of this dual-ring bracket versus the base of the single-ring stock bracket is in order. The quick release bracket's base is secured with a single screw.
This sounds flaky until you actually mount the bracket. Is is rock solid. It has curvature to match the radius of the OTA plus little rubber pads to give it a sure grip. The 10x50 finder scope looks good. I suppose one could use a different FL eye piece with it since it is removable. The finder scope diagonal has a compression fitting that locks the eye piece and illuminator down. Finder scope focus is smooth. The eye piece has an illuminated reticile focus adjustment.
It is also very smooth. The scope is clear and bright. Share Share this post on Digg Del. You currently have 0 signatures. Way to go! I'm also waiting for a backordered improved finderscope I think it's a very important accessory and it's got to work right for you. Congrats on the upgrade!

BT70 on VersaGo. I have one of those. I didn't like the shoe that attached to the tube, and I wanted to be able to move it around to other scopes , so I modified the stalk to fit a standard Orion finder shoe. This is a very nice scope in it's own right, you can see many DSOs in the finder, but I have a quibble.
With the helical focuser, the rotating EP clamp, and the fact that the illuminator swivels, there are three concentric actions at the EP end.
It's hard to figure out what to hold and what to rotate in the dark. The weight of the illuminator swivels the whole assembly sometimes. I tried to disassemble the focuser to put some machinist's grease on it to tighten the action a bit, but couldn't find a way in to the threads.
I do like the fact that you can move the illuminated reticle eyepiece between the finder and the main scope when polar aligning. Celestron 8mmmm zoom; lots of fixed EPs,some good, some.. A small collection of surveying instruments; a forest of tripods; Canon Rebel Xti.
We have been broadcasting our presence to the Universe for years now. If there is a detachment of Galactic Pest Control within light years, they are already on the way. All I do is astrophotography. I have never actually looked through my telescope. And, the only time I use the finder scope is for PA. BUT, even that limited time is a real torture without a right angle diagonal.
The correct image is just icing on the cake! WWPierre , did you machine the bracket in your picture which attaches the base plate on the rings to the base attached to your OTA? I agree with your statements concerning too many things to turn. Hopefully, I will become accustomed to not hitting the illuminator and screwing up the finder scope focus.
Time will tell. I thought about using a MiniBorg By the time one got a right angle adapter I don't know if they even offer a correct image thingy and an illuminator, it would be rather expensive.
Mhm, I wonder if I'm going to have similar problems with the StellarVue I ordered, with a helical focuser and "everything" rotatable. If it's too much of a hassle, apparently I can remove the diagonal and use a 2" EP for a straight through finder, which I wouldn't mind.
Sorry, computer acting up Pretty scope form Peter's picture , looks like the StellarVue I read the page about the Astro-Tech finder scope. Originally Posted by WWPierre. Darn it! I am in Windows Explorer.
Hang on Heh, back. Down the page, in red it explains that you need a bracket too. I didn't like the shoe that came with the bracket, because it was smaller than the standard Orion , and also I wanted to standardize the finder so that it would fit on all my scopes , so I decided to order a stalk from Hands-On. I needed to order two, because they had a minimum order. They wouldn't mail them to me, so I paid more than the items cost for courier. I expected them in a day or two.
A week later, the sky was clearing, and the stalks hadn't arrived, so I contrived the stalk you see in the photo above. A month later, the stalks arrived. I should also mention that the paralax adjustment for focusing the cross hairs is helical as well, making 4 concentric actions on that eyepiece. Page 1 of 2 1 2 Last Jump to page:.
