Hi,
Something I have been going to try for a long time and now I have two matching camera's, one Mono-ASI120MM, one Colour-ASI120MC-S made by ZWO.
I also recently acquired two matching mini mono cameras with different resolutions, that I want to use on the sun.
I have a little EQ6 of some vintage set up out on the front patio which I use from time to time, often for objects/events to the west.
Today was cool but fine and very windy, with some telescope buffeting making focus a little tricky. However, it was a good idea to set up the twin rig and see how it all focused. Normally for this I would have two computers, one for each camera so I see both images at the same time for focusing. I adjusted telescope focus for one camera, then made fine adjustments by unlocking the black ring and rotating the camera body until sharp, then tightened the locking screw. I took some still shots of the tower head (part of) with each camera but not downloaded them yet. The computer rig is on a trolley and just sits inside the atrium on the same level, so no hassle to wheel out and back in.
A rig like this on my 12" f/5 f/1.7 fork mounted Newtonian or Takahashi Epsilon 180 f/2.8 Astrograph will give me two images at the same time, one high res mono, the other in colour under identical conditions, great for comparison and two bites of the cherry, also a backup in the event one computer fails.
I am hoping to be able to test it in time for Monday night's Moon-Saturn occultation.
Let's face it, I enjoy experimenting and doing something different .
Clear skies...
