This little tidbit is not really related to the 14". I have a 10", but this will be an issue for ALL...
Meade was nice to include (for free -- well, sorta) a Zero Image-Shift Micro Focuser with all of the LX-850 SCTs. This device actually works quite well -- with one exception.
If you are into Astrophotography using a CCD (not dissing SLRs) and you use something a bit bigger than a DSI, the focuser will slip, causing focus to change -- and not in a good way.
I was using the ZISMF (Zero Image Shift Micro Focuser) for a few imaging sessions, and it was noce to be able to focus from my laptop. This all changed a few days ago.
I was imaging M82 near the meridian -- 6-hour sequence. After a few images, I started to notice fatter stars, then stars with doughnut holes in them -- the focus was now wrong.
My camera, filter wheel and adaptive optics come in at 6.4 pounds -- since M82 was quite high in the sky, the scope was pointed nearly straight up, with the full weight of the camera at the bottom. The ZISMF is a pressure/roller design -- I guess it just doesn't hold up under any real weight at the end of the optical train. Since I am imaginig that many purchaser of LX-850's will be using them for AstroPhotography, and have a fairly substantial camera at the end of it, this will pose a significant problem.
The LX-850 itself is performing quite well, and I have been able to get some really nice images -- which will continue as soon as I pull that ZISMF off the rear cell.
This device needds to be redesigned -- some sort of gearing, or at least a locking mechanism that can be engaged once focus is obtained.
The attached image will show what can happen -- the first image was quite sharp (I use a Bahtinov Mask), and the stars were small and sharp. This is the 6th Red image in the sequence.
