>>4167003It's a very simple solution to a few things.
It replaces one or both of the 17lb CGEM counterweights (that counter the C11) depending on the task, so total weight doesn't even go up. Replaces one when used as a guidescope (pic rel) or both when used as a secondary imaging scope with the 4" mak. Why not double your frames, amirite? Plus stacking from 2 different scopes helps to remove imperfections. I just need to get a longer dovetail plate to mate them. It can be used with the C11 too, but that will be too much weight for this mount since I'd have to add more counterweights. I'll get a 6" refractor to use it with most of the time, just using the same mount. It's strong but I don't want to push it too hard.
Yeah, I was referencing thermal mass... basically a giant heatsink. The sensor sits against a stainless cap with a thermal pad and the whole thing is threaded on with thermal compound. Specific heat of steel = 420 J/(kg°C) so you can basically expose for as long as you want. It will remove heat much quicker than air + fan, especially the tiny ones on astro setups where vibration is taken into consideration.
>spoiler: it worksI tested the sensor in it for 15 minutes and couldn't see any heat shimmer at all. When I used the sensor with the scope alone, there was a lot of shimmer. Basically, instead of sensor heat traveling up and into the tube and mirrors like a normal setup, it follows the path of least resistance directly into the steel. This will help with both imaging and guiding. No electricity, no fan, nothing to break. I like it. I'll machine an aluminum fork mount next, just for terrestrial use.
