Jiggered if I could use one though, although that is no slur on the actual mask, as operator error was the likely cause.
I went through a stage thinking I would use my Sony DSLR, but the major and really only stumbling block was focus. Long exposure was easy, I own a programable remote, but focus, accurate focus was an issue I couldn't resolve.
I made a Bart Mask, and tried it, but in the end went back to trying to eyeball best focus with a selection of downloaded images. If I could nail this with the B Mask I would look at this again.
In comparison to programs like Maxim, AstroArt, even Nebulosity where you use the FWHM, the B Mask was to me less than ideal. But, I see nearly everyone expounding their virtues, so guess I am the weak link here.
