Heya,

I picked up a small 127mm Mak (Celestron) to be a porch scope for visual, but figured I'd at least test it and collimate and image with it before it becomes that porch scope. So naturally pointed it at Venus. I plugged a manual filter wheel into its back with an ASI290MM and rotated through 3 minutes of capture time in Red (R) 610nm, Green (G) 500nm and Blue (B) near UV 395nm for the atmosphere and combined them via stacks of best 33% of each channel captured over those 3 minutes per channel.

Composite & Individual Channels:

Collimation on Sirius B:

Time, Date & Location (34 degrees Alt):

Celestron 127mm Mak + ZWO manual filter wheel + ASI290MM

Baader 610nm (R), Baader 500nm (G) and Andover 395nm (B, UV) filters

Very best,

Lovely end result, the UV is showing some very nice cloud structure.

Very nice image of what is a difficult planet for me.

I noticed the section with all the time, location information. Is that skyview with the houses, Trenton Fl.?

You might be my oldest daughters neighbor! She also lives in Trenton.
