M13 - Experimenting...

[Emanuele]

The same night I imaged M5 (see post in this forum), I did some experiment with my setup, on M13.

First of all, I started dithering. Am really not sure what is great about it, because I cannot see any improvement in the image. Or maybe I'm not looking for the right thing?
The second experiment was to image at different exposure times, from 2min to 4min, to capture different dynamic ranges of the cluster.

Enough of words, here's the data:

TEC140 @ f7
SXVF-M25C
Tak EM400
Exposures : 10x2min, 8x3min, 4x4min. No darks, no bias, no flats.

Thank you for looking and as always, suggestions and comments are welcomed!
