NGC 6744

Bernard Miller
 

Hi,

This is an image of NGC 6744. It is a spiral galaxy about 30 million light years away in the constellation Pavo. It is thought to be one of the most Milky Way-like spiral galaxies in our immediate vicinity, with flocculent (fluffy) arms and an elongated core. It also has at least one distorted companion galaxy (NGC 6744A). This image represents almost 50 hours of combined Ha and LRGB exposures taken in Australia and Chile in 2018 and 2020, respecively.

Comments and suggestions welcomed.

That’s a GREAT shot!  I’m bummed - brightest comet in 25 years and nothing but clouds here in the desert SW.  ☹️☹️☹️

Took it at the top of Michigan.  Still trying to catch a non-monsoon evening to capture the inner coma and nucleus at DSNM.

You captured that little “spike” on the end of the dark pillar which contains a protostar.  Bravo!

Hi,

This is an image of M20, also known as the Trifid Nebula. It is a combination of an open cluster, an emission nebula, reflection nebula, and dark nebula. It is located about 4,100 light years away in the constellation Sagittarius. I have posted both and LRGB and an SHO narrowband version. I think this gives a nice contrast to the difference between LRGB and narrowband images.

Vela SNR in bicolor narrowband

Bernard Miller
 

Hi,

This is an image of the Vela Supernova Remnant, or more accurately, an image of a small portion of the Vela Supernova Remnant. It is the expanding debris of a massive supernova in the Vela constellation that occurred about 11,000 years ago. The SNR is located about 800 light years away in the constellation Vela, which makes it one of the closest SNR in the night sky. While the entire SNR covers a span of about 16 degrees, this image is a mere 42x28 arcminute portion of the entire SNR. It would take a mosaic of hundreds of images of this size to encompass the whole nebula.

Comments and suggestions welcomed.

Bernard

NGC 4945

Bernard Miller
 

Hi,

This is an image of NGC 4945. It is an edge-on spiral galaxy about 13 million light years away in the constellation Centaurus. It is roughly the same size as our Milky Way galaxy with dusty spiral arms and magenta star forming regions clearly visible. This image combines data taken from two different telescopes; a CDK17 located in Chile and a 12.5 inch RCOS located in Australia. The combined data set represents over 39 hours of exposure.

Comments and suggestions welcomed.

Canon 5D Mark III, 25 second subs at ISO 1250, 25 total. Tracking on the iOptron tracker.  Lens was the Canon EF 70-200mm f/2.8L at 200mm and f2.8.

Processed in Pixinsight using a whole bunch of different processes, including the comet registration method to align the coma as well as ArcSin stretch, LHE and a few others.

Finished in
Photoshop to clean up residual gradients and color casts...

Hi everyone:

A couple more images of c2020 F3 NEOWISE as it slowly makes its way south and east in the evening twilight.  I was unable to see it visually, but captured easily with a telephoto lens in the northwest above the Tortolita Mountains:

Imaged it last night quickly in the NW. In Oregon it was higher than I expected. Will use a mini tracker tonite for longer exposures. Can't see it from the observatory so has to be portable...

Hi,

This is an image of RCW 58. It is a ring nebula about 13,000 light years away in the constellation Carina. It surrounds and originates from Wolf-Rayet star WR40, which is the bright blue star in the center of the nebula. Wolf-Rayet stars are massive (up to 20 solar masses), hot (30,000 t0 200,000 degrees Kelvin) stars that produce very strong solar winds. These solar winds ionize the surrounding gas producing the nebula. It is estimated this nebula is expanding at a rate of 87 km/s.

Comments and suggestions welcomed.
