Re: Small mount was Recent encoder discussion on CN

I guess if you need just an imaging mount with no clutches (no way to use manually without power), it can be very small and light weight.
A universal mount like the Mach2 or 10-Micron has more components than a non-clutched mount like the MYT or Rainbow mounts.
A non-clutched mount without encoders would be slightly less weight, and less cost, but will always require aggressive guiding.
A non-clutched mount with just an RA encoder to eliminate the periodic error would be medium cost and light weight.

There are a lot of permutations and possibilities, and it would depend on what you want to do with this mount. Some people just want a light weight mount that they can haul out from the basement to the driveway, put a scope on it, put an eyepiece on it and do a Moon Cruise or examine the planets. They don't need encoders or PE correction. Others want one as small as possible for airline travel and may or may not want to guide. Others want a precision universal mount that they can do anything with, but must have low weight because their back hurts. The possibilities are endless.

Low cost, medium or high cost. Medium weight low weight or ultra-low weight. Low tracking performance, medium or ultra-high performance. Clutched or non-clutched - universal or targeted. Single encoder or dual absolute encoders.

Pick any 3 out of 5.

And not just older people, but young enthusiasts who just want a lighter no-fuss mount that more easily travels when going on a group road trip where you have limited space for the Astro gear along with clothes and other travel essentials.

A real question is what is the smallest mount that would work with a AP105 and have encoders?  You might not save production cost over a mount that handles a C11 or AP130EDT — but if the mount is dramatically smaller or lighter, it could be interesting.
