Sharpless 201

Dan Crowson
 

Sharpless 201 (IC 1871, LBN 675 and others) is an emission nebula located approximately 10,000 light-years away in Cassiopeia. This nebula is often overlooked or imaged along with the more popular Soul Nebula (IC 1848). This one is on the opposite side of my previously posted Sh2-189 (https://www.flickr.com/photos/dcrowson/48201263231).

 

Luminance – 28x600s – 280 minutes – binned 1x1

RGB – 8x300s – 40 minutes each – binned 2x2

 

400 minutes total exposure – 6 hours 40 minutes

 

Imaged in November and December, 2018 and September and November, 2019 from Dark Sky New Mexico at Rancho Hidalgo (Animas, New Mexico) with a SBIG STF-8300M on an Astro-Tech AT12RCT at f/8 2432mm.

I originally posted a HaRGB version that can be found here - https://www.flickr.com/photos/dcrowson/48207081791. I’ve been finding that I can get a better image using luminance when under very dark skies.

Cool.  Almost looks like it’s hiding behind the field stars.  Thanks for sharing.

Hi all:

Sh2-209 is a very faint emission nebula in Perseus; there aren't many images of it.  It is shown in an image from the WISE infrared telescope.  NGC 1528 is a beautiful open cluster about 50 arcminutes to its east:

NGC 2467 - The Skull and Crossbones Nebula

Bernard Miller
 

Hi,

 

This is an image of NGC 2467, also known as the Skull and Crossbones Nebula. It is a star forming region about 17,000 light years away in the constellation Puppis. This region does not represent a single star cluster, but rather many separate clusters along the same line of site, each with different distance and radial velocity.

 

Comments and suggestions appreciated.

Thanks,

 

Bernard

Re: M33

Not I. I think the last time I went was 04? when I gave a talk - long time ago. I always get a cold if I go to large gatherings and/or travel on the airlines in the winter so try to only do those things in the summer or early fall - so sadly AIC is history for me.

Nice catch. I did not realize how many comets there were flying around until you started posting. Evidently, the vast majority can't be seen with the naked eye.
