About

My name is Erik Guneriussen, from Norway, born in 1958 as a profession i am software engineer. Here is a small presentation related to astronomy. Other interest like salmon fishing and golf has become second hand interests the last years so they are just mentioned as a curiosity.

 

My interest for astronomy started with the subject Mathematical Geography at high school. That interest was limited to inspecting the sky with nothing else than the eyes before I became 50 years old. That "limitation" was solved by my wife when she gave me a Meade LXD 75 mount and 6” Newton telescope. She has regretted her generosity more than once.

 

The LXD was the first months only used for viewing. The first touch of imaging was a test with a rebuild webcam of Saturn. The result was terrible, have not tried plant imaging since, but the interest for imaging was born.

 

Season two started with my first CCD camera, a Meade DSI Pro II Mono. I still have the camera and use it as guide camera. Today I think that selecting the DSI camera was an excellent choice. Almost immediately it was possible to take images, mainly caused by excellent capturing software that could be processed with at that moment a “reasonable” result. Image of Cresent nebula from August 2009 on right is one of the first images captured is. The colors are as far as I can remember added by use of one of Noel Carbonis actions.

 

 

The best image with the DSI was taken a night with exceptional seeing. About 60 exposures of 25 seconds through a 10” SN gave a really detailed image of M51. One of the first stacked images is the one of M51 at right. Later I got a Meade DSI II Color that was used to the RGB that was added so that I got this image: M51

Pity I had not heard about flats so that the dust knots that covers the image could have been removed.

 

The DSLR then took over as main camera. The DSI was used for guiding which gave me the opportunity for long exposures. Long in this context means 3 minutes which was a huge increase compared to max. 30 seconds.The first decent image was as shown on the right of M51.

 

At the same time the interest for processing really started. M42 was the first, I am not sure how many hours I spend processing this image. I assume that I made hundreds over versions. With great tips for many I ended up with a decent first long exposure image. Not the easiest object, I would have been better to select another easier one. Link to M42 Image

 

From my point of view the imaging realy started when I bought a used Starlight Xpress H9 Mono with filter wheel equipped with Astrodon filters. Suddenly it was possible to image with good result even if the moon is shining. With rather unstable weather conditions and short season this made a huge difference.
