I did make a hartmann mask a few weeks back, but find there's still that little bit of uncertainty with the focus, will have to have a play with it to see if I can get some sharper spikes, plus I always leave the damn thing on
I've done a bit of reading up about getting a IR filter, but don't think it's worth it at the moment as I'm in the planing/research stages of upgrading the camera along with some nice astronomik filters
, besides my adapter is an old bottomed out film canister super-glued to the camera housing
