Hi Everyone.
Had a couple of clear (and hot) nights last week which give me the opportunity to image the Rosette nebula. I found it to be a very photogenic target and had a lot of fun capturing and processing the data.
Only glitch on this one, apart from the temp being 23c at midnight, was PHD2 was losing the guide star at the end of most dither commands sent from Backyard Eos. I tried everything , changing settings and searching google. Ended up just baby sitting PHD by re selecting the star manually each time it was lost. Would have preferred snoozing on the lounge than sitting at the laptop.
I did manage to fix the problem before the second nights run. I updated to the latest version of PHD2, which ran perfectly.
Taken with the Canon 60Da at F2 using the Hyperstar lens on C11 Edge HD.
170 x 90sec subs @ ISO800. Calibrated with darks and flats. Processed in Pixinsight.
EDIT: I've replaced the original uploads with new amended image. Different colour balance with slightly better star cores. Both old and new versions are on Astrobin for comparison, the link below now opens new image.

Thanks for looking
