Comet P/Wirtanen (46P)

Comet P/Wirtanen (46P)

Komet Kudo-Fujikawa C/2002 X5

The comet was observed on the 28.th of january 2019 22.16 UT +. No Moon. FFC 150 mm, HEQ5, Atik 460EX. Unguided. 17 pics a 60 sec, darks, flats. Orientation inverted. DSS, Astroart7. Clear weather, -5C.The comet was observed on the 17.th og january 2019 at about 22.30 UT. with the Moon at colongitude 52 degrees at a distance of 54 degrees. 8 pics a 60 sec. Darks and flats. The doughnut was impossible to remove, but has a beaty all by itself. Unguided. Of note: a field with a galaxy cluster and therefore strewn with countless tiny galaxies.Background had a very low NELM

Moon 93% Waxing gibbous

IC1848 - Soul Nebula

Quick NB test

500 frames of each channel R,G & B. About 50% from each channel has been stacked and combined.My first try with narrowband combination, HOO in this case. Unfortunately my framing was more of than i first anticipated :)I recently recieved my new Baader Ultra Narrowband HA filter and wanted to do q quick test

SN2019ein in NGC5353 + surrounding galaxies

I imaged SN2019ein during the testing phase of the new scope and thought it was a pretty nice FOV so i ended up making an actual image of this area.

La Luna

Double Cluster in Perseus

The Elephants Trunk in Bi color

This is an image of the Double Cluster in constellation Perseus. These clusters are approximately 7500 lightyears away, but approaching us at a rate of around 38-39 km/s. Each cluster contains about 300 blue/white supergiants. The age is estimated to be around 12,8 million years old, which in astronomical tearms are very young. The data was captured while waiting for my real target, The Pleiades to rise over the roof of the neighbours house. Unfortunately it was extremely moist that night, and both guiding and image quality suffered from it. Very basic edit of this data was performed in PixInsight. WBPP for calibration and stacking using darks, flats and flatdarks. DBE on each master. RGB combination. Photometric color calibration. TGV and MMT denoising. Multiple rounds of Histrogram Transformation (stretch). Desaturate background with curves. Multiple rounds of Curves for contrast boost and color tweaking and saturation. Morphological Transformation with Erosion to soften stars and bring some more color into them. Resample to 50% for webposting. 80xR @ 30s Unity gain 80xG @ 30s Unity gain 80xB @ 30s Unity gain

Arp 186 / NGC 1614

A Hydrogen Bird - IC5070 Pelican Nebula in H-alpha

M1 Crab nebula in bi-color

I am very facinated by the irregular galaxies from Arp's catalog and love to photograph them. So after seeing Gary Imm's image of Arp 186 the other day (https://www.astrobin.com/6dxtcr/0/?nc=user), this galaxy was on my list. Sunday evening, it cleared up over Denmark, however, the seeing was poor, FWHM over 5" and a nasty skyglow was eminent. Further more, at 55° latitude north, Arp 186 at almost 10° south declination didn't make the task easier. Arp 186 rised around 17:00 CET in the nautical twilight, but I had to wait until 18:15, where Arp 186 was at about 18° altitude and had just cleared the observatory walls. Due to the skyglow, I keep exposure times at 120 seconds. Guiding wasn't great, probably due to the poor seeing. L: 26 x 120 s R: 24 x 120 s G: 23 x 120 s B: 23 x 120 s 50 x 120s darks + 25 flats and 25 flatdarks for each of the four LRGB filtersThe weather didn't allow for O-III data. That must wait.
