Re: G11G Imaging Weight Capacity for Imaging?


 

Hello Francisco,
?
Do not get me wrong, I firmly believe at the under $5000 budget Losmandy makes the best mounts in their class.? I owned a G11T for a year.? I thought I wanted two rigs,? it was for my C14.? It moved the C14 around, I used it for visual and it was very good.? However, I also owned two refractors at the time, that C14 was noticeably heavier to push across the grass. I donated the C14 to my local middle school for their astronomy program, the mount went to my neighbor.?
?
As Michael above pointed out,? there are a lot of things that affect pointing and tracking when doing DSO imaging.? I know you said you are just trying it out and not really going to do it. That is great.?
?
Image scale is what you need to track under.? Your periodic error has to be less than your image scale you are shooting at.? With a 2600 camera that has 3.76 micron pixels, you need to guide under .4, that is a 12 LX200 OTA with a .63 reducer.? With a 2400 camera you are at .64, more manageable but still kind of tough to do.? My opinion.? Reason,? you have a 14" barrel that is over 24" long with a dew shield on top of that mount. A 6" RA and Dec gears driving it. ?
?
My opinion, ? a mount with a 10" RA gear and 8" minimum Dec gear.? If you get serious about DSO imaging with a 12" SCT.? If it were me, and I know this is a Losmandy group, but with a 12"SCT for DSO imaging successfully an AP1600GTO, 10 Micron 2000GPS,? a Planewave or ASA mount .
?
At 50 pounds you are approaching the weight limit,? physical size you are probably over the limit, focal length you are past the limit.? The least little thing and you are done. No room for error. A gentle breeze of wind, someone walking around.
?
Planetary, visual yes. EAA yes.? DSO, I'm going with no.? Final answer.
