Mediocre* C23 cluster, Perseus cluster and Pleiades images

[ELS]

Interesting noise patterns in these.
I remember why I didn't like DSS... The C28 cluster images only got 9, 5" frames stacked because DSS has a low limit on the threshold for accepting frames, So it discarded all the other 81 frames. I was actually aiming at M33 but somehow ended up way off

There might be some galaxy in there, just need to figure out which blobs they are

Pleiades was brighter and it accepted all 21 4" exposures.

The Perseus cluster image was 100 6" exposures @ 90mm

Hard to get the color accurate on the larger stacks, seems to get very non-linear. I might have to stop being lazy and take dark and white frames and calibrate everything.


:D
