Nebula Thread - post your images of Deep Sky Nebula's

[Jeff WX1USN]

Decided to experiment with the mosaic and the S30 on both sides of the Veil Nebula C33/34.

I am in a Bortle 8 area with lots of trees. I started the imaging at 10:30 using the plan feature and at midnight it went behind my trees. I used a 2x mosaic and proved that it could be done but I need more exposure so tonight I will go out and try to determine what time it will come out from behind my trees in the east.



I did get something, just need to keep trying.



I don't think you can stack mosaics from multiple nights.

Couldn’t you take them to Photoshop?

This shot is of the Veil Nebula both C33 and C34 a 5 night mosaic with the S30. The first shot is the live shot that the Seestar created and the second is the overall mosaic showing how it creates the final shot. Both were tweaked in Lightroom. It really is amazing the amount of coverage the S30 can give. These were a combination of a 2x Mosaic and a 1.7 Mosaic combined in seestar processing.

Yes you can, I also have Pixinsight, but at least two of the groups I belong do only allow processing to be done in the scope.

But, don't you need post processing to pull out all the information in the file?

Yes and no. Some targets are great with onboard processing others you can't see anything without post processing. I will say that virtually images are better with post processing but the facebook group below doesn't allow any post processing as they want people to see what you can do with only a Seestar.

Oh, I see. That makes sense, yes.

Caldwell 19 - IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection[2]/emission[3] nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470.[4] It shines at magnitude +10.0[5]/+9.3[3]/+7.2.[6] Its celestial coordinates are RA 21h 53.5m , dec +47° 16′. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39.[2][5] The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago;[7] the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years

Caldwell 11 the Bubble Nebula with the Seestar S30

 

[Jeff WX1USN]

Went out with the S30 and S50 last night. Processed in the Seestars, to try to avoid the color cast a lot of people and shots are getting I tried less contrast and negative saturation before the denoise. I tweaked in Lightroom. IC1396 the Elephant Trunk and the HIP image with the S30 are the same nebula you can see IC1396 in the upper right.

NGC7380 the Flying Horse Nebula (or Wizard Nebula) taken with the Seestar S30

NGC 7380 is a young[4] open cluster of stars in the northern circumpolar constellation of Cepheus, discovered by Caroline Herschel in 1787. The surrounding emission nebulosity is known colloquially as the Wizard Nebula, which spans an angle of 25′. German-born astronomer William Herschel included his sister's discovery in his catalog, and labelled it H VIII.77. The nebula is known as S 142 in the 1959 Sharpless catalog (Sh2-142).[2] It is extremely difficult to observe visually, usually requiring very dark skies and an O-III filter. The NGC 7380 complex is located at a distance of approximately 8.5 kilolight-years from the Sun, in the Perseus Arm of the Milky Way

IC5070 the Pelican Nebula, labeled here incorrectly as NGC7000 although it is part of the N American Nebula NGC7000

The Pelican Nebula (also known as IC 5070[1]) is an H II region associated with the North America Nebula in the constellation of Cygnus. The gaseous contortions of this emission nebula bear a resemblance to a pelican, giving rise to its name.[1] The Pelican Nebula is located nearby first magnitude star Deneb, and is divided from its more prominent neighbour, the North America Nebula, by a foreground molecular cloud filled with dark dust.[2] Both are part of the larger H II region of Westerhout 40.[2]

The Pelican is much studied because it has a particularly active mix of star formation and evolving gas clouds. The light from young energetic stars is slowly transforming cold gas to hot and causing an ionization front gradually to advance outward. Particularly dense filaments of cold gas are seen to still remain, and among these are found two jets emitted from the Herbig–Haro object 555.[1] Millions of years from now this nebula might no longer be known as the Pelican, as the balance and placement of stars and gas will leave something that appears completely different.

M1 the Crab nebula from last night with the S50

The Crab Nebula (catalogue designations M1, NGC 1952, Taurus A) is a supernova remnant and pulsar wind nebula in the constellation of Taurus. The common name comes from a drawing that somewhat resembled a crab with arms produced by William Parsons, 3rd Earl of Rosse, in 1842 or 1843 using a 36-inch (91 cm) telescope.[6] The nebula was discovered by English astronomer John Bevis in 1731. It corresponds with a bright supernova observed in 1054 C.E. by Mayan, Japanese, and Arab stargazers;[7] this supernova was also recorded by Chinese astronomers as a guest star. The nebula was the first astronomical object identified that corresponds with a historically-observed supernova explosion

took shots of Messier 1 the Crab Nebula a supernova remnant in Feb of 2024 and Feb and Mar of 2025. I decided to run them through Pixinsight this evening to see how long 1,400 fits files would take to process, it was about 90 minutes.
