I use a Bahtinov mask for stars etc but I don't know if they help with video /cam work on planets? Somebody could correct me!

Hi I think the 9.25" SCT should be okay with a 2 x barlow folcal ratio of 10 and focal length of 2350mm (But I too am not totaly sure). I have notice a few good shots out there with 2 x barlows and 8" scopes but the cameras used may be better too.
