Amazing!

Back in the 60's and 70's one had to use spacemission to capture those details. 

Very nice!

Very nice photo. That's a pretty awesome outcome for first light on any device.Thanks for sharing.

I hope I'm not out of line in asking: Who is the manufacturer of your 8" Newt and is the 3100mm your OT focal length?

It is a Celestron Starhopper, one of the newer metal tube ones so a standard Synta product. They make pretty solid f/4.9 mirrors all the time so I figure f/6 should be even better. It's a 1,200mm stock focal length but I measured the pixel width of Venus to calculate that my 2x Orion Shorty Barlow is giving me about 2.6x magnification.

Thanks for the reply. I'm not very familiar with the astro photography jargon.

You need to label your images with N-S and E-W.

Here is from the evening of 1/30/20. I used a IR(G)UV color palette to map the uv reflecting cloud bands to red.

I do? Isn't it apparent with the phase?

 

You need to label your images with N-S and E-W.

Really great captures.

 

I'm wondering what exposures you used on this. Your image label says 10ms (1/100 sec). I use a Baader U-filter on Venus and can't capture anything less than 200ms (1/5 sec) even with maximum gain due to the very low light transmission, which obviously means that you can't capture the seeing. Just wondering how you manage to get such short exposures.

 

I'm using a 3x Televue Barlow, Omegon RC8 (effective focal length 4800) and an Altair GPCAMv2 130 Mono camera.

Yes, I used 10ms and 300 Gain for this one. Just a basic 2x barlow and 0.16"/pixel.
