2019 - Solid Mount with Clamshell Rings and Altitude Bearings.

We've decided to move the altitude bearings to the inside of our mounts, to eliminate any potential for lateral slipage. This mount is for a Takahashi MT-160 (6.25 inch Newtonian). In these photos we are testing the altitude motion with temporary new stips of Formica Crystal 909-42 material. They worked very smoothly with excellent "sticktion", emulating the previously prefered but no longer avaiable ebony-star material.

This is just delivered, and buyer's remarks upon receipt:

" It looks great! Can't wait to take it for a test run."


2019 - Tripod/Table-Top Solid Mount with Fitted Bearings.

We had a request for a Dobsonian mount to adapt to a tripod, for a 6 inch f/5 newtonian. This "grab and go" telescope is intended for use when conditions make placing the telescope on the ground difficult, such as snow. The photo bottom right shows the adapter to fit on a CG-4 tripod. The CG-4 adapter and plate may be removed allowing use of the OTA and mount as a table-top telescope. Bottom left image is during dry fitting parts, snowing front view.

"Just beautiful! That is one good looking mount. I like the design, it feels secure. The mount is solid, buttery smooth and rock solid. I couldn’t be happier."


2019 - Solid Mount with Clamshell Rings Altitude Bearings Finished:

This mount was built for a heavy MN66 Mak-Newt, so we worked with the buyer to sufficiently stiffen with both internal and external bracing. Our collaboration continued even after the mount was delivered in order to test and adjust the stiffness."I did the upgrades last weekend and tested several times during the week.

I'm glad to report that the mount works fine now. Looks great too."


2019 - Solid Mount with Altitude Bearings kit..

Here is Will's finished 10" SkyWatcher. He asked for the ground board to be completely under the rocker box, which makes it more compact for travel. Notice the offset mounting of the bearings and nice eyepiece holders inside the front board.

"I confirm that the tube now balances nicely. There is no problem collapsing the tube with the larger, offset bearings and show how much bulkier the stock mount is (the stock mount does result in the eyepiece being a few inches higher but the difference is not much, and I actually prefer it slightly lower for my usual chair).

Take care,

"Finished the scope this. Thanks for your help. My 3 granddaughters and I painted out Zodiac signs on the scope and mounted the optics this weekend. Having your mount available made the job a lot easier for me.

2019 - Big Bearings replacing 5" factory bearings kit.

"Was able to use the SkyWatcher Dob with the Big Bearings upgrade. Super smooth motions in alt. Very happy with the results so far.

"Mark worked tirelessly with me on my mount project. I had many ideas for customization and changes that I wanted to make and he worked with me on every single aspect of it. He would not rest until I was satisfied and his attention to detail and commitment to his customers is truly amazing. Thank you again for everything you did, Mark. I am truly grateful and very happy with my mount.

Thanks, you guys do great work.

2018 - Solid Mount finished.

"Thanks Mark, you know I have never left the scope in the living room. The black wood mount just did not look living room worthy. Beyond functionality and weight, your mount looks great and I am happy to have in the room now. Will be sure to let folks know where it came from.

I know this is about the most simple mount you make, but it is still a great change for this scope and I am glad I finally did it. It is so much lighter, and a heck of a lot nicer than the standard mounts that come with these or any similar scope.

"Hi Mark:

The weather hasn’t been too great around here lately for observing, so I haven’t been out under the stars with the telescope, but I do have it operational now. Here are a few pictures I took today of the mount with the scope and finder installed.

2017 - Solid Mount with Clamshell Rings and Altitude Bearings kit.

"Hi Mark,

The telescope is working very well. I added encoders to use with my Argo Navis. You did a very nice job on the mount as the pointing accuracy is very good. The scope is an Orion ( English) VX10L, 10" f/6.3. Thank you for all your help with this project. I am happy to recommend your products and services.

Thank again.

2016 - Collapsible Mount and Altitude Bearings kit:

"Mount works perfectly, going from zero to slightly over 90 degress. Altitude movement is silk smooth; azimutal movement is firm and precise. Mount height and tube clearance were spot-on! There´s about one inch of clearance.

Ron asked for a replacement for his 10" Orion mount, and a clamshell with bearings 6" to fit the 10" mount. Two telescopes one mount!

"Stand arrived this evening. Great job! Looks super, works great. The most amazing part is that it weighs 1/1,000th the weight of the original Orion stand!! Geez!! The real reason that I wanted the mount, so I could put my 6" to good use also. I had no mount for it before, now it looks good enough to sell. BUT - I won't!!" Ron DeAngelis
