Here is a close of the new riser. A bracket was made of aluminum and than a finder bracket, think it was an SV was attached to the bracket. I found some matching screws off of a laser holder and I painted the aluminum bracket with a black felt pen.

Here is one more image showing how the finder bracket was attached to the SV finder bracket and the need for longer screws to tighten the finder. Hope this helps, because it really works.

That looks great, Bill! Pitch it to ES. Maybe they'll market it

Hi Bill,
I've gotten an extra mount along with some rectangular aluminum, it order to do some 'surgical engineering' on my ES finder bracket/holder. My question to you is by how much was yours lengthened in order to make it more / comfortably usable?
Thanks
Bob

I swapped out the finderscope on my Omni102XLT with my Orion 9X50 RACI from my dob.....just ordered another 9X50 RACI. Anybody know where you can get the Celestron Omni Blue and White paint? I'd like to paint the new RACI Scope/holder with the Celestron colors (just nit pickey I guess).

Check the image with the bracket in my hand. The main part is a SV finder bracket and the lower part was just an aluminum wedge to fit the ES bracket slot, so maybe 4" or 5", just enough to keep my head off the OTA. Since then I'm ready to try the original SV finder, which is a RTA finder with reversed image and illuminated reticule. Because of Winter, probably won't be able to try for awhile.

This spring I hope to add a MoonLite focuser, which has 2 finder brackets, so might keep the ES finder on the ES mount and add a RTA to the MoonLite bracket. I can't use the SV bracket, not standard and would need for the modified ES bracket. Having 2 finders would also add more weight to the back. Having seen how nice it is to have brackets on either side of the OTA, it really makes it easier to use on an EQ mount. I never saw the advantage till I saw a MoonLite focuser with the 2 finder brackets.

Bill

The problem with the ES 127 is there is not a finder shoe, but a slot, so simply adding a finder is not an option and the reason I had to have a home made piece to fit the slot. It's hard to believe ES didn't see the problem, with their excellent finder, that is a straight through design. Our clubs ES152 does not use a straight through finder, so maybe they did see the problem and future ES127's will have a different finder. Some of the latest posts say the current ES127 doesn't even come with a finder, but don't know what kind of finder bracket shoe it might have.

Right, I got that. But I'm going to use a peice of aluminum and add it to the post. I can add an inch or 3" or anywhere in between. So I was wondering how much height was added. The clamp, shoe, etc, is not a problem for me.
Thanks

I found that an Orion 9X50 RA finder fits the rings perfectly on my ES127.

Straight through finders work well when the finder is at the sky end of the scope as is the case with most Newtonians but most refractors mount the finders close to focuser end which makes them awkward to sight through. I hope that Explore Scientific someday soon changes the standard straight-through finder for a RACI.

4- rough cut, then file, then 60grit sand, then hand block plane for edges and square. Whew. This material is hard.

Looks good, but images are a little small , should make using the finder much easier.
