Off the Beaten track - NGC1893

Thats a very nice image Kieth, Certain well rounded stars. Perhaps a tad larger than they might be. I can't see any vignetting either. Maybe a tad at the to corners is a little darker than the center. Anyway lots of flats will sort that to a large degree. 5 is not enough. I always take 25 as a standard set, since they are so short its no extra effort. About bias frames, I don't use em either for the reason Dave gave.

Thanks Dave, it's hard to keep the size of the stars down a little, I capture in RAW, and after stacking, I convert the file to TIFF format, before working on it in Photoshop, I find that in the TIFF file, the stars are always quite small, but get a little larger when i brighten the image a little due to my limited 90 second exposure time since I am not even autoguideing yet !!
