Seeing was not good hence the small # of stacked frames.Took note of Dave P's thread how he was now using more gain & gamma confidently, so I took the liberty of trying it for myself.
Normally I will use zero gamma & as little gain as I can get away with to minimise grain.
I'm now doing the O'l venus trick. Shooting it just after the sun sets. If I wait till dark all I get is a wobbly orange blob with no detail because it's gotten too low in the 'mirk'.
Only the one 2X barlow & extension tube, but I have to resample in registax to get this scale. (1.3X)
Soon I'll be shooting it in broad daylight (if I can find it!)
A cracker of a Shot Asi! very clear albedo feature I assume must be Syrtis Major...
I saw the cloud map yesterday and the hole above SA and though hmmm wonder what Asi will be doing tonight...
well done! Must give the Twilight a go too - have to wait till the weekend as it's generally already getting dark by the time I get home during the week and by the time the scope's cooled getting past 8pm.

Brightness: 40%
Gain 25%
Gamma 25%
6" refractor & toUcam.
nice one,
i would have thought 900 frames will whip that grain away. my best saturn of 77 frames and jupiters are all 250 - 400 frames with high gain (50%) and gamma (50%)???
