I was lucky with the weather and got several chances to do thermal (1 micron) imaging of the Venus nightside surface during this evening apparition.  I'm still experimenting with processing, but that could go on for months ( ) and I figured I should post something.  This is from the evening of 16-July-23.  Special thanks to CN member John Boudreau for all of his advice on this subject!

 

Celestron Edge 11

Thor Labs 1000 nm high pass filter + Edmund 1025 nm low pass

ZWO ASI462MM with sensor cover glass and window removed

 

15000 frames; exposure 75 ms and gain (FireCapture) 240.

Sunset 20:21 MDT (UT minus 6hrs)

Video covers 20:56 - 21:16

Venus altitude 11.3 -> 7.3 degrees

Sun altitude  - 6.9 -> -10.3 degrees.

 

The features are a pretty good match to the WinJUPOS topo map.

I have no good eastern horizon, so that's probably it for me till 2025.

I know very little about thermal imaging, but this looks excellent compared to most images I've seen. Very clean looking, with clear surface details. Well done!

Remarkable image!

Superb.

 

If you want to sell a 462mm with sensor glass removed, there'll be a small but incredibly keen market!

Incredible result
