I don't usally post pictures on CN because I am a very beginner, and It already takes me a lot of time to set up everything, capture and process images; moreover, I am doing more EAA than Hi-res. Anyway, three nights ago I tried for the first time my new planetary imaging setup, consisting of an ASI 290MM, an Explore Scientific Focal Extender (2X), a ZWO EFW and the Baader RGB filters (I didn't use the Luminance filter). So, these are my very first images of Jupiter and Saturn, taken on 23 July from a pretty dark location on a high hill in Sicily.
I've surely made a lot of mistakes, but I must confess that I'm not unhappy with the results! I used Firecapture, then processed the three .ser videos with AS!, improved each channel separately with Registax, and finally composed the RGB images in GIMP.
Regarding exposure and gain, I set 33,3 msec. with 170-180 gain for Jupiter, and 100-130 ms and 230-260 gain for Saturn. What do you think about that? Maybe the gain for Saturn was a bit too high, the image looks noisy (and I probably failed to perfectly align the three channels in GIMP...).
I'm totally open to criticism, advices, and any other kind of comment. Tonight I'm setting up everything again, even if there's a bit of saharan dust in the sky, brought by the wind.
