That MN86 is an impressive and imposing scope.  I didn't realize they were so heavy.  That's the same weight as a C14, and it's interesting to see it on what looks like an AP1200 (maybe 1100?).   

 

Are those rotatable rings?

 

I see many MN users have their scopes on alt-az configurations which would bypass the eyepiece positioning issue, except for altitude.    And some appear configured for photography where it doesn't matter.

I have entertained the idea of buying a mak newt and putting it on a dob mount, since they can be somewhat heavy for their aperture. A good dob mount is not only sturdy, it usually is inexpensive.  smile.gif

A few people have gone that route. One problem you end up with is the corrector it makes the scope very top-heavy, much more so than a secondary cage spider and secondary mirror and focuser. And it will need a solid tube

Here are a couple of photos of my Intes-Micro MN-86 - a rather heavy instrument but with wonderful optics.  It works nicely on my home-made Dob mount.  The tube rotation rings allow for the eyepiece to be in convenient position wherever the scope is pointed.

Wow, beautiful job! That is really, really nice. Any chance I could talk you into making one for my MN66? :-)

I have a Teeter dob base hanging around my house from an incomplete 8" dob project.  Some extra wood to take up the extra space due to the smaller tube and I managed to get my HD 145 on it.

 

Practically speaking, an 8" f/6 dob has an less than convenient eyepiece height.   The base is best used raised up on a couple of 8" cinder blocks.  Also, because the tube is short, you tend to have to sit really close to the scope which causes some inadvertent knee bumps..  It works but the ergonomics of a Discmount DM6 on a Discmount  tripod are much, much better..  OTOH the latter system isn't quite as 'grab and go'....

Hi Dave,

  How are you liking the HD145 on DM6?

 

I am thinking of maybe going that route.

I know the question was intended for Dave, but FWIW I'll give you my take.  The DM6 is excellent with the Ceravolo.   Balancing is effortless and there is generally no need for re-balancing during changes of eyepieces, etc.  The operation is very smooth and virtually vibration free.  I can't imagine a better Alt/Az mount for the HD145.  If you do end up with one I'd recommend ordering the pier extension with it.
