At Saturday's NEAF a presentation was given on using a diffusor instead of defocusing in photometry.

Does anyone have experience with this technique??

Diffuser on b_Per Campaign

Peter:

Don Collins ran his recent b_Per campaign using the diffuser on BSM_NH2. It gave better data for his project than defocusing on the same scope and others.
