Sh2-261
Sharpless 2-261, also known as Lower's Nebula, is a faint emission nebula located in the constellation Orion. Sh2-261 is an ionised hydrogen (HII) region energised by the ultraviolet radiation of nearby hot stars. This nebula lies roughly 3,300 light-years from Earth and spans about 50 light-years in diameter.
Sh2-230
Sh2-230 is an H II region in the constellation Auriga, approximately 6,800-9,800 light-years from Earth. The nebula spans 16–26 light-years in diameter. The large region known as Sh2-230, but within this region, there are many more, often better known objects, such as M36, M38, Sh2-229, Sh2-234 and Sh2-236 ad Sh2-237.
IC4954 and IC4955
IC4954 and IC4955 are two very small nebulae in the constellation Vulpecula. The total field of view of this image is only 12 x 9 arcmin, so very much zoomed in on an already long focal length telescope. Each night only 0.5-1.5h of data could be collected, so this image is the result of 20 imaging sessions.
Sh2-200
Sh2-200 is a very dim planetary nebula in the constellation of Cassiopeia. By mistake it ended up in the Sharpless catalogue of HII emission regions, but recently its identity as a planetary nebula was confirmed. The nebula itself and especially the hydrogen regions around it are very dim, so require long exposure times
IC-434
IC434 is better known as the horse-head nebula and one of the most well-known nebulae at the night sky. The image here contains just over 2h of exposure, taken using a travel rig during a trip to Scotland. Updates to the travel rig had been applied, the most notable being that it is now run using Stellarmate on an iPad mini.
Sh2-86
Sh2-86 is a rather faint nebula in the constellation Vulpecula at a distance of approximately 6000 lightyear. Especially the OIII and SII signals are very faint. But during processing they could be retrieved well. Using the Hubble Palette, the final result is rather impressive with the big pillar structures in the nebula.
Sh2-105 | C27
The Crescent nebula, also known as Sh2-105 and C27, is an iconic deep sky object in the constellation Cygnus. In 2018 this object was imaged, so the current image gives a good idea of the progress that has been made over time.
M16 | Sh2-49
M16 is also known as the Eagle Nebula, but the central part of this nebula is made even more popular by the Hubble Telescope, and is nick-named the pillars of creation. Here in a narrowband version with a total of almost 40h of exposure.
IC59, IC63
A tricky target to image. The super bright star Gamma Cassiopeia, surrounded by the hydrogen-rich but faint nebulae IC59 and IC63. A combination of broadband and narrowband images allowed capturing both aspects.
