The Pelican Nebula. 3 hours of 180s exposures using a hydrogen alpha filter. Bit of a stormy region in Ha.

The moon in I band.

My setup is not really great for the moon, but experimented with imaging the Moon at approximately 17° elevation using a infrared filter meant for photometry.

This is the stacked 10 best images of 120 0.01 s exposures.
Telescope: SW 200mm Quattro
Camera: ZWO ASI 1600MM Pro

I use a monochrome camera and take different sets of images with luminance, red, green and blue filters. I need to a stack these image sets to improve SNR and then combine them to a create a color image. City imaging also means I have light pollution effects that I must remove.

Messier 106, NGC 4248, NGC 4217.

Messier 106 from this spring. Forgotten for some time in a long backlog of processing.

LRGB Image from the city (Bortle 6/7).

Just tested it. Worked very well, will use again for sure.

Image of NGC-2174 - Monkey head nebula

Monkey Head Nebula - NGC-2174
Nice autumn/winter narrow band target from my balcony.

Approximately 1.5 hours Ha, 3 hours OIII, coloring is H(HO)O. Used some sharpen to put a bit more focus on the details in the nebula.

Rosette nebula in HSS (Ha as red, SII as green and blue) coloring, looking stormy and menacing.

Playing around with color mappings. Narrowband image of The Rosette nebula with a HSS coloring. Data from 13th of november.

Astrophoto of galaxy NGC2903 centered, with NGC 2916 in the upper left. According to Stellarium 2903 is 38M lightyears away, while 2916 is 187 lightyears away (which I think means it is big and bright).

First light on blue sky! Vestland had clear skies for once. NGC 2903 centered, NGC 2916 upper left. 2916 is 187 M ly away according to Stellarium, 2903 is 38 M ly. The smaller galaxies in the field are around 100 M ly. So 2916 is pretty big I think.
