Mars this evening with an open sky. Seeing was good but towards UT22h00 conditions changed with moderate to bad seeing.

Halloween Sunspots

The Sun is active again as we can see some sunspots. Two group of sunspots (AR2778& 2779) can be found near the limb of the Sun.

The picture is a combination of two pictures, both with Nikon D7500 and TAL200K f/8.5:

1) Solar film ND5, ISO 500, 1/800s 

2) Solar film ND5 and Solar Continuum filter, ISO 800, 1/80s

Stacking is done with CS4.

Supernova SN2020rcq

UGC 6930 (Uppsala General Catalogue of Galaxies) is part of the M109 group and located in constellation Ursa Major and about 50million ly away from Earth. The galaxy shows an "extra" star which is a supernova (SN2020rcq). The picture was taken with COAST C14 f/11 telescope on Tenerife. Exposure time 120 and no filters. I embedded a picture of UGC6930 from Simbad to compare with the Coast picture.

New Bright Comet Atlas C/2020 M3

After the great comet Neowise C/2020 F3 this summer there is now good news. We will be seeing again a bright Comet, Atlas C/2020 M3. Not as bright as C/2020 F3 but still worthwhile to get out. It's currently mag 8.5 and increasing. The comet was discovered at magnitude 19 on June 27, 2020, by the Asteroid Terrestrial-Impact Last Alert System or ATLAS..

It's currently visible in constellation Lepus and moving toward Orion. For more information see The SkyLive.
