PN NGC6369 comparison – 10 min vs. 5 min subs

Hello,

Using NGC6369 as a target, I have been trying to investigate and improve the auto guiding on my Tak EM200 GEM as I haven’t paid too much attention to chasing down some annoying source(s) of star elongation since I acquired the mount.

The difference in the faint tendrils of nebulosity above and below the PN really demonstrates the importance of obtaining better data through longer sub frame exposures; although I think I may have lost some detail due to some auto guiding excursions that I am still trying to track down.

Tak Mewlon 180 at F9.6 using x0.8 Flattener; SBIG ST7E CCD camera for image capture and auto guiding.

Cheers

Dennis
