One Scope to Rule Them All

Have a look at this video that Ron sent to me:

I want him to call it a Caterpillar Drive!

As to the baffle discussion, perhaps it has been discussed on CN in the past, I might do a search there.

Looks a lot like the Optec Rotating Focuser

With the help of a few folks, supplier discussions, and this thread , I have decided to go this way:

• The MN190 will be retained, a no-cost option, it is a wonderful scope for visual and imaging, and gives me everything I need right now (except for a hernia).
• The Bresser 152mm Corrected Achro will be kept for the time being for continued narrowband imaging in a lighter weight package, and visual use by the grandkids.
• I will purchase a a TS Photoline 115mm f7 APO: as shown here:

which will give me a light weight (6.4kg), wider field option when equipped with a reducer/corrector (going to f5.53 at a focal length of 632mm) which is a good match for my ASI1600MM camera, and it will still give me a fl of 800mm at f7 with just the flattener when required.

• This decision is within by budget (even with the reducer/flattener which are being purchased separately). My other scopes, including the 10" Newt and the iStar, will be sold over time when buyers can be found, and should go along way to paying for the TS 115mm APO.

Thanks to everyone that made suggestions, provided advice, and kept the ideas flowing.
Let's close this thread down now.
Thanks to everyone.

That seems like a very good choice. I look forward to your review of this scope.

I agree with Greg, sounds like a very nice 4.5" visual scope
