I have been trying to get started with photometry and have found that AIP4WIN does not seem to be available any more. The book that it is supplied with is no longer on the Willman Bell website. I have been trying Muniwin which produces files for AAVSO and has an option for the BAA version but when accessed it says “yet to be developed”. Regards, Graham Winstanley
