The Little Dumbbell. KG Observatory, Julian, CA.

When I first tried this object, I found it difficult to expose any fine detail. RGB seemed a bit "blurry" and L had no additional detail.

It turned out Ha exposed some structure and OIII to a lesser extent.

What you see here is RGB with a Hard Light Ha blend at 75%. I then did a screen blend of a starless OIII (no red channel) at 40%. This helped intensify the blues.

Overall the star field color matches the RGB and the nebula color matches the RGB with a slightly more intense blue from the mild OIII blend.

"The Little Dumbbell Nebula is a planetary nebula in the constellation Perseus. It was discovered by Pierre Méchain in 1780 and included in Charles Messier's catalog of comet-like objects as number 76. It was first recognised as a planetary nebula in 1918 by the astronomer Heber Doust Curtis. However, there is some contention to this claim, as Isaac Roberts in 1891 did suggest that M76 might be similar to the Ring Nebula (M57), being instead as seen from the side view. The structure is now classed as a bipolar planetary nebula. Distance is currently estimated at 2,500 light years.

The Little Dumbbell Nebula derives its common name from its resemblance to the Dumbbell Nebula (M27) in Vulpecula. It was originally thought to consist of two separate emission nebulae and was thus given two catalog numbers in the NGC 650 and 651. Some consider this object to be one of the faintest and hardest to see objects in Messier's list."

IC 1848 The Soul Nebula | Luca Fornaciari Astrophotography

This is a very extensive HII region, whose distance is estimated at 7600 light years from us; its gas is illuminated by the stars of some clusters and associations of nearby stars. The light is then re-emitted by the nebula in the typical red color of the H-alpha hydrogen emission lines. Inside the nebula, star formation is very active.

This is one of my favorite areas in the sky, located in the well known star cluster The Hyades. The two most prominent objects are Sh2-239 in the lower left, and NGC 1555, known as Hind’s Variable Nebula or Sh2-238, in the upper right. Both of these feature Herbig-Haro objects. Embedded in the molecular cloud LDN 1551, Sh2-239 contains HH 102. Hind’s Variable Nebula is also know as HH 155. As a variable nebula, it can periodically change due to variations in the triple star system T Tauri that illuminates it.

Love this picture. Very stark and evocative. Great composition and colors.

This is a fantastic picture to get lost in. Extremely deep, with sparkling colors.

No blue central star is visible inside the possible PN.

Thank you, Ann
Of course, there is a blue central star Thomas

Ah, okay! Thanks, tommy_h!

The east pole of the moon

The moon is usually seen in subtle shades of gray or slightly yellow.
The different colors are recognized as corresponding to the actual differences in the chemical composition of the lunar surface. Blue hues reveal areas rich in ilmenite, which contains iron, titanium and oxygen, mainly titanium, while orange and purple show relatively poor titanium and iron regions.
White areas are taller areas that are more exposed to the sun.
Trips to the moon have already been indicated by similar images.

This picture has been taken in the Alps in September. I stayed around 2000m of altitude in order to get rid of a maximum of light pollution. I wanted to get a shot of the Milky Way aligned with the path to "connect" the land with the sky. Bise (the place where this picture has been taken) is one of my favourite spots for hiking which is why I decided to give it a try for nightscape.

Hi friends!
I’m Carlos Uriarte Castillo, from Tarragona, Spain. I’m amateur astrophotograper and I will to send my new photo.
the Iris nebula, I think it is the photo that I have taken more hours. Sum of two late summer, 2018 and 2019, so I have accumulated almost 21h of exposure.
As always, in the field, transportt tackle up and down, calibrate, counterbalance, put into station every time
