Bernard:

One of the best I've seen! I think the addition of the Ha makes the difference (and being imaged from down under). Thanks for sharing it.

Hi,

This is an image of NGC253, also known as the Sculptor Galaxy. It is a spiral galaxy about 11 million light years away in the constellation Sculptor. It is a starburst galaxy which means it is undergoing a period of intense star formation. The data was captured by Martin Pugh and processed by me.

Suggestions and comments welcomed.

The brown cast version is the original. The new one is much bluer.

Hi Bernard

Honestly, I prefer the original version.  The reprocessed version seems to have  brown cast. While this may be more realistic, I’m probably biased by images I’ve seen in the past.

Hi,

 

I posted a version of this image earlier this week. Thanks to feedback from Bruce on the Planewave group I too another run at it. He pointed out a post by Bob Frank about the reddish hue of this galaxy due to its low galactic altitude, and how to correct it. You can see more detail here.

Based on this information, I reprocessed the image and I have to admit, I like the new one better. If you are not tired of this one by now and wouldn’t mind taking a look at the new image (top link) and the original image (bottom link) and letting me know which you prefer, I would appreciate it. Thanks to Bruce and Bob for some great feedback.

Sh1-89

Dan Crowson
 

Sh1-89 (PN G089.8-00.6 and others) is a faint planetary nebula located approximately 6,400 light-years away in Cygnus. This object was noted on Sharpless’ 1953 catalog. It was determined that it was a planetary nebula by the time the second catalog was introduced in 1959.

 

Luminance – 24x600s – 240 minutes – binned 1x1

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

 

360 minutes total exposure – 6 hours

 

Imaged November 7th and 8th, 2018 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.

The reflection nebulae vdB29 and vdB 31 are about 1 3/4 degree apart,
with vdB 29 in Taurus and vdB31 to the northeast in Auriga:

vdB 31 is surrounded by the dark nebulae Barnard 26, 27 and 28:

vdB 29 has some fainter dust surrounding it:

The luminance data from this image suggests that the dust may be common
