Alt: 18°
Seeing: 3/5
8" Dob, Asterion Ecliptica EQ-Platform, ZWO ASI462-MC, 3x Barlow, ZWO ADC, 850nm pass for IR, W47+IR Block for UV.
---------------------------
IR=Red
UV=Blue
IR&UV 50% Blend=SynG
Sharpened IR=Luminance
---------------------------
Tried a little variation to the usual IR(g)UV approach. The red channel here is minimally sharpened IR. The luminance channel is the same IR stack but super cooked with wavelets to wring out as much detail as possible. This is why Venus's illumination looks less than it actually was. This is definitely my best Venus yet, very happy with the final result!

Excellent image. It does show nice clouds. Out of curiosity, why not sharpen the red channel and omit the luminance? Was there much benefit or does it help mask the bright side during sharpening?

Very impressive detail considering youre using  a colour cam.

I was getting a lot of blue when trying to balance the colors with the heavily sharpened IR as red. Also, it just looks interesting this way.

Very nicely imaged and processed, an excellent end result
