First image of Proxima (centre), for getting a "feelling" for correct exposure and attempt to do photometry (usind AstroImageJ... awesome package BTW.... with very steep learning curve, but I well get there....)
Image below is obtained from single RAW frame (just some stretching applied in DPP for better visibility), 64 sec with MC Rubinar 10/1000 and Canon 60D (standard).. no filters (next time I will use L-Pro filter to increase contrast).
For actual photometry CR2 files need to be converted to TIFF format (which can be read and processed by AIJ)
