M1 crab nebula

Posted By Stefano Vezzosi
Hi guys,
this is my first attemp to image M1. Technical details:
Celestron C9.25 @ f/6.3;
Losmandy G11 with upgraded worms and the third bearing in AR/DEC shafts;
SBIG St7E NABG ccd camera @ -18°C.
The exposure was of 10 minutes selfguided at a rate of one correction per second with SBIG relay box; the seeing condition was not good, some high veil in the sky; moon was up during the exposure.

Imaging Team: Stefano Vezzosi, Alessandra Zucchelli, Angelo Mannucci, Giuseppe Iacopini and Manola Neri from Florence (Italy)

Any comment would be very appreciated!

M74

Posted By Stefano Vezzosi
Hello,
this is the result of the averaging of two exposures of ten minutes each, with a St7E NABG ccd camera in selfguide mode. The main instrument was a C9.25 at f/6.3 on a Losmandy G11.

Comments appreciated.

The owl nebula, with the small galaxy near it. This image is the result of the mean of two 600 sec exposures and one 300 sec exposure, with a St7E Nabg and a C9.25 f/6.3 on a Losmandy G11.

M3 ST7E

Posted By Stefano Vezzosi
Hi, this is my first attempt to imaging M3 at full resolution (C9.25 @ f/10) with a ST7E NABG camera.
8 minutes integration, selfguided by the tracking CCD on a Losmandy G11 mount.

Very little image processing... DDP, no flat frame applied.

Comments are highly appreciated!

Clear skies, -stefano

ngc 4565 @ f/10

Hi everyone,
another shot at f/10 with the Celestron 9.25 and the Losmandy G11. This time I've averaged three images of 12 minutes each, selfguided by the St7E NABG.
The seeing condition was bad, as a tipical windy night...

Comments appreciated!
PS: the moon was at first quarter too!
