Right Angle Finder on a Star Tracker Pro
4

Once I decided to buy a tracking device, my next issue was whether I could get one equipped with a right angle finder. When you have a bad lower back, crouching down to look up 40 degrees or more to align with Polaris is likely to be an excruciating experience.'

Alas, manufacturer of affordable tracking devices seems to even offer the option of a right angle finder.  So, I decided to purchase a Star Tracker Pro and take a chance on being able to fabricate something that would work.  What follows is a step-by-step of how to duplicate what I did.

I suppose it may be possible, with great care, to drill a small hole in the top side of the plastic tube and and drill a slight indent in the polar scope optical tube so a screw could be tightened to more securely attach the entire assembly.  However, I haven't tried that as yet.

Very interesting, but unfortunately, this is a different make of tracking device and it's not clear their adapter would fit on the Sky Tracker Pro.  And if you can't read French, you might have a difficult time placing an order in any case.

I suppose the Sky Tracker Pro has a very similar attachment, but I'm not sure, you can find the precise size of the adapter below on the comment section.
The guy can and does print stuff on requirement too, so he could easily build one for your tracker, he speaks english as you can see on the comments, so no problem messaging him in english.
I cant speak french well and still had no problem contacting him and buying adapters, they are well made and cheap, I havent find anything similar anywhere else.

Federico,

I looked at the message section at the bottom of that web page, but I have no idea what to put in the Site Address line.  The only reference I've ever used is my email address and that message box says that's not enough.

The Polarie is completely different from the iOptron, and the Polarie's PA scope design/ in use function is it's weakest point.

I'm not sure what that has to do with the subject of this thread; that is, how best to attach a right angle finder to the polar scope of a Sky Tracker Pro (which I obviously already own).

Re: Right Angle Finder on a Star Tracker Pro

Federico,

Thank you for bringing that site to my attention.  I've contacted Phillipe and he has assured me that his creation will be compatible with the polar scope of the SkyTracker Pro, and I've placed an order for one with him.  I have no doubt it will prove my effective than my own cobbled together device shown in this thread.

He's probably misreading my link, that says at some point "viseur-polaire", thinking it would be an adapter for the Polarie mount.

"Viseur polaire" means polar scope in french, it's NOT Polarie the mount(slightly different spelling, watch attently).

This is excellent! I admire your ingenuity and appreciate the thorough step by step photos and descriptions.  Do you have a link to this process online somewhere else? I'd love to share this information in my post about the SkyTracker .  Thanks

Actually, I've ordered the 3D printed adapter from France and expect it to arrive any day now.  Once I have it, I'll post an image of it on the Sky Tracker Pro.  If it works as I suspect, I would NOT encourage anyone to follow my process.  The 3D print adapter only cost $14.50.

I said I'd post an image of the 3D printed adapter (Green part) mounted on a Sky Tracker Pro once I received it, so here it is ...

It works like a charm and, using the Pentax DSLR adapter that came with the Neewer 1x-2x right angle finder, the RFA is securely mounted and should not come loose or fall off in use.

A bargain at $14.50.  Forget my handmade jury-rig; this is much better.

Re: Right Angle Finder on a Star Tracker Pro

Howdy Folks,

Inspired by this thread, and my aching back: I made my own design similar to the french design. Mine is made from SLS Nylon instead of FDM printed PLA. It also can use metal screws, and doesn't require a secondary adapter. I also made a lens cap for the right angle lens.

Because mine is made by Shapeways, it costs a bit more, and doesn't include shipping, so I understand if folks order the french one.
