After the masterpieces from planetary imaging experts, here is what you can get with the ASI120MC without many experience (these are my first Mars and Saturn). The telescope is a 10" Orion Dobson adapted to an EQ6. The Jupiter image is with a 2x Barlow with an exentsion tube (so it's working more than 2x for sure). Saturn and Mars ones are with a projection with a 10mm Plossl (the Orion that came with the scope). I'm looking forward to improve by studying works of others :-) The biggest problem is that there are few nights with good seeing, I guess the best thing would move to Atacama desert :-)
