Hi and welcome to my astro homepage, which have one purpose only, to show and share with you my best astro pictures taken from Copenhagen, Denmark. Kind regards

The obs. picture shown at the right side is from 2005. 

A afternoon in 2005 with very special weather conditions when the sun disappeared below the horizon. The observatory at that time was not finalized and among other things the rotating roof was not yet made and mounted.

13. Aug-2017. First light with a portable setup. A M31 Lum picture taken from my backyard. Total exposure time 1.5 hours. Subs from 30 sec. to 120 sec.,

A Ha filter and TTS-160 mount test done with 3x600sec exposures,

Old color picture of M31 added to the Lum M31 version above (the color FOV don't fully cover the Lum version),

10. July 2017, a M27 WF OIII/Lum picture, ~3.2hours in total exposure,

10. July 2017, a M27 OIII/lum picture, ~1.5hour in total exposure. The individual frames were taken in/on a full moon sky & in the usual light polution from the main capital of Denmark, Copenhagen,

2. July 2017, a section of the moon, just a single Ha picture! The best one I have taken so far, that is called "lucky imaging". Picture size is 80%,

2. July 2017, a moon picture, put together as a matrix of single moon pictures, using the same photo setup as described below,

2. July 2017, a section of the moon taken with a 16" SCT, Atik 460ex mono camera and a Ha filter. It is one single picture enhanced slightly in photoshop, no stacking performed,

21 June-2017. Between the clouds in the sky and in a very bright summer night I was able to get, with my 16" SCT, 12x300sec OIII and 11x300sec Ha subs, now added to the below BW M27 image. On purpose I have moderated the stars in the cropped picture,

21. June-2017. A M27 version with old color info. added (the FOV in color picture was smaller),

18-19 June-2017. The first M27 2017 picture. It is a Lum mixed with Ha info.

5-6-2017. A matrix moon, single pictures, taken with/through a Ha filter. Equipment used: 16" SCT and a ZWO ASI1600MM cool camera,

28-5-2017. Galaxy NGC6947, in total 9.5 hours of exposure. The Ha part was 30x300sec frames stacked and integrated into the red channel, which make it into a Lum,RHaGB picture,

23-5-2017. Latest  color picture version of the Galaxy NGC6947. Changed the color and used the lowest Lum FWHM's stack,

20->21 May-2017. Color data, Ha, R, G and B added. WO FLT-110/Atik 460 ex mono R,G,B exposure = 3x20x180sec. 16" SCT/ZWO asi1600mm cool R,G,B exposure = 3x30x120sec. Ha exposure = 12x300sec.

The 'close-up' picture, ~7 hours of exposure,

Came out observing 19->20 May-2017. A couple of Lum pictures that covers this event: Supernova SN 2017eaw and NGC 6946.

An gif animation, a 'before' and 'after' Lum picture,

and a WO FLT-110, Atik 460ex mono/lum picture,

A close-up Lum merge picture of old and new NGC 6946 frames,

Here I used the best 6% frames of a 20GB SER movie of the Moon. The cropped picture was taken 8 -> 9 May-2017 and the picture size is 100%.

A section of the Moon. The picture was taken 8 -> 9 May-2017. Two sorted stacks of frames were merged together in Photoshop,
