Starship Asterisk*

Recently I have been working on reprocessing old imagery using new software and techniques. This image improved a tremendous amount in noise and star colors... This image is the result of the cooperation between three observers. Images were made with different equipment and combined to get this deep...

Here is an image of M27 I took last year and which I reprocessed using pixinsight. This way you don't see M27 very often...

Recently got a trial for pixinsight and started reprocessing some recent images. This is NGC7822 or Cederblad 214 in hubble palette...

Here is my latest version of Melotte 15 in the Heart nebula. For the image 12.5 hours of data was used...

9x1800s Ha (4,5nm)
11x1800s OIII (3nm)
10x300s R,G,B each for the star colors

The sun had some great filaments yesterday. They went over more than 1/4th of the sun and continued over the edge as can be seen in this image.

Recently I have been working some more on the Heart Nebula. This is my result for now...

Last night I used the TEC-140 to record an entire night IC1805 (Heart nebula). I imaged from about 12 midnight to 6 in the morning while I was sleeping. Results was 11 images of 30 minutes in OIII. I combined these with my earlier H-alpha images. Then I created a synthetic green channel from the H-a...

Yesterday I succeeded in imaging 168P Hergenrother...

Here is the image... (full size here)

Here is the latest and I think best version of my NGC7822 image. Stars have much improved since the previous version:

Last night I finally was able to gather more data to finish my NGC7822 image in hubble palette.

The image was made using a Tak FSQ106 with SXV-H9 ccd. A DMK618 was used for autoguiding on a NEQ6...

Ha: 16x1800s 4,5nm
OIII: 6x1800s 3nm
S2: 4x1800s 5nm

Congrats to you to! I didn't directly make the link between geckzilla and Judy

I also made a starless version of my Cygnus mosaic. This clearly shows the beauty of the nebulas in this region:

In the last few days I was able to finish my mosaic of the Cygnus region in H-alpha. I used 4 nights for this, partly because of shifting manually the field between exposures (using thesky6 to help me). The images are made with a Canon 100mm lens @ F2.8, a geoptik adapter and my SXV-H9 camera. I use...

This is what they call a lucky shot...

How would the sky look like if we could see h-alpha radiation with our own eyes? This image comes close. It was made from 9 images made from my backyard using a 100mm Canon lens with a SXV-H9 ccd camera. It's the tail of the Swan (Cygnus). cygnuspanorama_cropweb.jpg The full scale can be found here:...

Last few days I have been experimenting with my Canon 100mm lens on my CCD camera. This to gain experience for imaging during my holidays in Austria. In the end I used 3 nights for this image. The experimenting took its time, but I think this could have been done in one night. At least now I know ho...

The sun is getting ready for the transit. Activity is rising, so let's hope for some nice imaging opportunities...

A nice dark nebula in the constellation of Taurus, IRAS 5437

And Mars as seen from Hubble in 2003:

Another nice galaxy with a lot of h-alpha activity near the center NGC 3256: http://farm8.staticflickr.com/7210/7003662318_3266166cd1_z_d.jpg Datasets used: HST_9735_21_ACS_WFC_F555W (green) HST_9735_22_ACS_WFC_FR656N (red) HST_10592_34_ACS_WFC_F435W (blue + lum) HST_10592_34_ACS_WFC_F814W (red + lum)

I'm not sure about that. But when I look at the original hubble images it looks like there is indeed a sort of a pit there with less density.... It looks like the galaxy is thinner in the central part in stead of having a bulge, but I can't explain why. Maybe an astronomer can?

Wow, I never dared to hope for this..

A full zoomable 35 megapixel version of the image can be found here:

I succeeded in upgrading my M106 image with Ha data from the Hubble. This makes the red signal better detailed and improves the quality of the image in my opinion:

Here is the final result of my M106 hubble processing. Unfortunately the F435W and F814W data were not clean enough to generate a good color image. So I decided to combine the Hubble data with groundbased data. This is comparable with what was done with the famous Eta Carina image of Hubble where al...

I just started with a 180 megapixel mosaic of M106 of the hubble data. Here is the first layer (555nm), which is still under progress. The image in the link is 50% of the original size (it's huge!).
