Hi guys, inspired but Ross G.'s great barnard loop I was hoping to give it a shot tonight in Ha with a 65mm Pentax lens. I have a small bathinov mask for focusing that hopefully will work.
I'm a total noob at this lens business so I'm asking: do you need to refocus often with a lens like this or is it fairly stable? Also I plan to come around now and then with a hairdryer as I don't have dew straps. Do you reckon that'll do the job?
Thanks for any tips.
