Hello
before the arrival of a week of bad weather in the south of France I quickly made a series of films on Mars with my homemade 625 mm newton a 742 nm filter a 5X barlow televue a QHY 5III178M camera and above all low turbulence , I was able to get my best image of Mars.
Many craters are visible. This confirms that the best part of a big telescope is the sky.
4 mn acquisition at 125 img/s 1500 img stacked on 30000 with AutoStackkert 3 processing with Registax 6 and Photofiltre.
Clear skies.

Cassiopea al 50% by Raul Villaverde, en Flickr

I just spent a lot of time identifying all the bright stars and nebulas in this fabulous picture! Thank you!

Ann

thank you very much.
The mosaic grows little by little. To this day, he already has 25 photographs and it looks like this.
A greeting.

Thank you! It's a truly lovely and highly resolved mosaic of most of Cassiopeia and a bit of Perseus!

Thanks again!

Starburst Galaxy IC10.
KG Observatory, Julian, CA

My second project with the new ZWO ASI6200M Pro – this time with 2x2 binning for smaller sub size (30 MB vs 120 MB) and higher SNR. The 2X loss of resolutions is not really noticeable. (-:

Camera gain was fixed at 100 with 60s Luminance subs and 300s RGB and Ha subs. Several hours of luminance subs were discarded in favor of the best FWHM.

Ha was applies over the LRGB with a starless screened overlay to help highlight the vigorous star-forming regions.

Fortunately the great positioning of IC10 allowed me to capture lots of subs – 9 hours per day from 8:30 PM to 5:30 AM over 3 days. Before that we had 8 days of high-altitude smoke from the CA fires. Skies were very dark, but just a handful of visible stars.

"Lurking behind dust and stars near the plane of our Milky Way Galaxy, IC 10 is a mere 2.3 million light-years distant.

Even though its light is dimmed by intervening dust, the irregular dwarf galaxy still shows off vigorous star-forming regions that shine with a telltale reddish glow.

IC 10 is the closest known starburst galaxy. Compared to other Local Group galaxies, IC 10 has a large population of newly formed stars that are massive and intrinsically very bright, including a luminous X-ray binary star system thought to contain a black hole.

Located within the boundaries of the northern constellation Cassiopeia, IC 10 is about 5,000 light-years across."

Thank you for all your galaxy images! I really appreciate them!

You're very welcome Ann! And I really appreciate your feedback.
