It's very good, but beware of the 5.75 inch rear focal plane requirement.? You can go inside of that limit ok, but not past that else you get lots of coma and ...trouble.

It's a heavy monster.? I'm getting old!

Re: Finding stars
Using the Handset you are limited to the initial Bright Star list for one first star, but after that you can use:? Object database, Stars, and pick your star...plenty there. But if your Gemini is connected to a PC, you can try this... using Stellarium instead you can Model with any object whose center you can find (planets or deep sky too.? See attached PDF describing the way I use. Best, Michael On Fri, Aug 28, 2020 at 10:44 AM jeff marston <jeffmarston@...> wrote: Hi everybody.

Re: Balance and height
Hi Dave, I believe you have it right...it's really the only way to mount a long Newtonian with a heavy rear mirror. In that case, the eyepiece will be way out in front of the mount. I mounted my 10" f/6 Newtonian on my G11 for quite?some time with good imaging results. ? That had the conventional primary mirror with the flat back, so it could float on 9 tilting rear cell pads. ? I know that US premier mirror maker Robert Royce also makes mirrors with a conical shape to reduce rear cell weight, and those have a single mounting bolt.? Mine was one of his mirrors with the usual flat back and is very heavy. ? If you have a heavy camera, then this will tend to counterbalance the rear mirror weight. If you do mount a camera, I found that putting the camera with the eyepiece facing downward helped eliminate side flex of the tube. If you do not have a heavy front camera, then I guess you could mount some weights near the tube front to counteract the weight of the rear mirror. ? The G11 should be able to autoguide and handle the scope with no problem. The opposite case is also found: a heavy triplet refractor will have its front lens close to the DEC axis center, and the rear eyepiece will be way out in back.? Again, one can put weights toward the back in that case, to help get the scope closer to the midway point. ?

Balance and height
A double edged question if I can please, I balanced the telescope (250mm Newtonian)? in its tube rings while it was on its Dob mount, is this an ok method?
As the scope is rear heavy? the rings are closer to the rear of the scope so when it goes onto the G11 and is pointing upwards the eye piece is nearly 8 feet of the ground, no good for viewing.. Have I mounted the telescope correctly?? Thanks in advance |
