Hi,
quick update: I added a mercury 2010 chart to the ephemerides. Quite a lot opportunities to image mercury at max. elongation during daylight – I’m looking forward to the messenger of the gods.

Hi,

several users of the TIS DMK21 series cameras reported ring like ghost image artefacts in their images that seem to duplicate bright highly contrasted rims in the images. I tried to reproduce these artefacts with an indoor test setup and have been successfull. The artefacts appear when the camera is operating at 60 frames per second only. It seems that 60fps should be avoided for our imaging application, what a bummer :( Please read the complete article for details.

Clear skies,
Oliver

Hi,

I had to play around a bit and create a mars observation chart 2010 for my location for the ephemeris page.

Mars Chart 2010

Mars Chart 2010

Mars will reach culmination heights around 60° over here at least. I hope this will compensate for the max. apparent diameter of only 14,09” during the upcoming opposition. Hopefully the weather will be more imaging friendly during the holiday season than it has been so far for the beginning mars season.

Clear skies,
Oliver

P.S.: Image scaling looks awfull on Explorer6, click image for full caption then…

Hi there,

I haven’t been able to do some real imaging for quite a while. During some indoor camera testing I found a couple of unprocessed lunar AVIs on my imaging laptop that I have captured 2009.01.06. and started to remember: Seeing was quite bad, I tried to image Plato with the C11 and a 2x barlow but gave up soon – no steady image at all – the evidentiary AVI is still on my disk. I stepped down and plugged the DMK2104AF directly into the focus of the C11 to capture at least some low resolution shots for a mosaic. I started at Plato and worked my way over to Sinus Iridum, across Mare Imbrium to Archimedes, Copernicus and the terminator. The result is quite chaotic but considering the conditions (seeing, it was really frosty and I had to clear a lot of snow prior to imaging and a nasty influenza was already on its way inside me…) I’m happy I processed the already forgotten footage. The Hortensius Domes east of Copernicus came out quite nice.

Please click the preview image for the full capture size

The mosaic is a 8 patch piece, each patch is a stack of 156 from 4444 frames in AVIStack. I’m a little unsure about the tonal balance since I processed the image on a new display. Any feedback is highly appreciated!

Best wishes & clear skies,
Oliver

Hi  there,

I started a new series of articles related to imaging artefacts of various kinds. Article #1 is online: Diffraction pattern artefacts.

Besides, I started coding proper W3C validated pages using CSS, should make life easier in the future…

Hi there,

after several years of editing any site-news of astro-imaging.de cumbersomely more or less manually in html I decided to take the plunge to set up a ‘Blog’ to make daily editing so much easier. I’m not interested in a fancy ‘what I did today’ style Blog but see the blogsoftware as a neat content-managment and publishing tool. Nevertheless this Blog will see additional entries besides the classic site-update-notes like thoughts and news regarding imaging our solar system so stay tuned.

Clear skies,
Oliver
