Description

I decided to try using the QHY294M on M13 to see how much better resolution I would get compared to the  168C.  In addition, I now have a dedicated field flattener; shouldn't make a huge difference in the middle of the frame.  Here is just over an hour of luminosity data from the 294 blended with only 12 minutes (?where did all my old M13 OSC data disappear to? ).  Quite a difference!  I might go out further on the limb and try the same target with the 47 MP mode the camera offers just for fun.

Title: more OSC colour!

Description: Duh! extracted the L from the first version and added the new hour's worth of colour data. Good thing, as my new lum data has flats trouble and is marginally useable.
