Looking back thru this reflector forum I do not see many threads on Aperture dobosonians. Looking at Opticsmart web site the dobs seem to be fairly priced and well equipped. They have options for them also at time of ordering. I do not see who makes there mirrors listed. I only found one review on CN review section which was pretty good. But its only one person using it. Any information pros and cons appreciated. Thanks
Apertura Dobs are manufactured by Guan Sheng Optical in Taiwan. GSO has a long history of manufacturing "commercial" Dobsonians. The first commerical metal tubed Dobs, the Orion XT-series was manufactured by GSO about 14 years ago.
Orion's normal supplier was Synta after a couple of Orion switched to Synta, GSO continued to manufacture Dobs, for some years Hardin Optical was the US importer. Today, GSO manufacturers the Meade Lightbridges, the Zhumell dobs, the Astro-Tech Dobs and the Apertura Dobs.
My own 10 inch F/5 is a GSO, I have had it for more than 10 years.. It's one of my favorite scopes.
Today, you have a choice between Synta/Skywatcher/Orion and GSO. GSO generally represents more value, if you want a straight starhopping Dob, GSO has the good focuser, better eyepieces, a better finder for your money.
If I were buying another tube dob, I would buy either an Astro-Tech or a Apertura. The scopes are essentially the same but it's a question of support, both these companies are comparatively small companies that are focused on serving the needs of the amateur astronomer. They provide knowledgeable support, these are companies I want to support..
At this moment, Astronomics is out of stock of the Astro-Tech Dobsonians, so I would be very happy to buy an Apertura from David at Opticsmart.. He's an amateur astronomer himself...

Be prepared for a long read, like make a pot of coffee.

The only point I would consider again when buying a 10" dob is that if one wants digital setting circles, which I have since come to wish I had, the Orion is the only version with them built in. Which is to say, even with Orion's generally poorer price/ performance (IMO), it costs more to retro fit the circles, and they are a bit of a challenge to install.

I now split my time with my other scopes and sometimes have all three out at once
