Starship Asterisk*

Here is a long exposure narrowband image of the wizard nebula. In total 16h Ha, 4h OIII and 3,5h S2 data were used in combination with ED80/110 refractors and an SXV-H9 CCD camera.

Here is an image of the Elephant Trunk made with my SXV-H9 and ED80 telescope. Full frame can be found here:

Here is an image which was posted in an earlier version a few months ago. Now RGB data was added to introduce real star colors instead of the hubble palette colors... In total the following exposures were made: Ha: 6x1800s (ED80 4,5nm Custom scientific)/6x1800s (FSQ85 5nm astrodon) OIII: 7x1800s (FS...

Not a fancy image this time, but something at least as exciting I think. I recently stepped into the topic of photometry. Doing measurements I found high accuracies and so I took up the challenge to detect an exoplanet from my backyard. Two days ago there was a transit predicted of Qatar-1b, an exop...

Ok, here are two to start with: Sunspot AR1302 on two consecutive days http://www.astro-photo.nl Copyright: André van der Hoeven http://www.astro-photo.nl/raw/sunspot_1302_25-26092011.jpg Sun with AR1302 on 25th September http://www.astro-photo.nl Copyright: André van der Hoeven http://www.astro-pho...

I remade the M27 earlier submitted with extra OIII and Ha data gathered in the last two days. I think this version is much better than the earlier version and I think it's quite a different view of M27 than what I'm used to see..... Exposures: C11 f/6.3: H-alpha 5x30 minutes with 4,5nm custom scient...

Last week I made images of M27 with my ED110. I decided to combine these images with Ha and OIII data taken with my C11 earlier this year. So in the end I made a widefield (well a bit) with the details of the C11 in the core. Exposures: C11 f/6.3: H-alpha 5x30 minutes with 4,5nm custom scientific fi...

Here is a series of moonimages I made in the last week where you can see the differences in time when the shadows change their shapes and the moon is differently lighted.

Here is an image I made of the harvest moon the day before yesterday. It was made in RGB and I used saturation and levels to highlight the color differences between different parts of the moon. Clearly the mares and young ejecta patterns can be recognized by their colors... (19:30 UTC image updated ...

First of all I would like to thank everybody who has voted for our image. It was a real great feeling to see we ended this high in the poll. As a starter in this field, I really thought we had an APOD and you can imagine how good our weekend was. Later I found out that the poll (although officially ...

We wanted to wait for the poll to end before posting an updated version of the Pelican Nebula we made. We think this one is better in color and detail. We hope you agree....

Daniel Verloop and myself have worked last month on the pelican nebula with the following result. In total about 27 h of image data was used.
