Hi all I have finally managed to get out and do some imaging for the first time since mid February. It was also a chance to try out the H9 camera and 7 ...
Hi again As usual when I post my images, I looked at it on a different computer and monitor and saw a bit of a gradient so I went back to the drawing board and...

Hi, Up here, 65N, astronomical darkness is fainting away In a few days. I have to quit imaging untill Autumn. Next dark night will be at September 8. Here is a...
Hi all Sometimes bad weather can be a blessing in disguise as it allows a bit of catch up time in the processing department. I posted this image here and then...
I got a Proline 39K last week after a very long wait. Back in November I spoke with Greg about replacing my KAF09000 sensor with another one. I had been...
kodak and sony sensors are pretty different for sure Terry this is a full frame so it needs a shutter I think the sony ccd sensors are all interline, right? ...
Hi Richard Very nice, look forward to seeing the images when you manage to get some more decent imaging time in, try sticking to less pixels though, have you...
hi gordon  it took me a while to find m42 on the full res as well. I was everywhere trying to find it.  39MP is a lot of pixels and it will be good seeing...
actually M33 will be pretty amazing: it will fill the FOV using the AP180EDT.... 39 million pixels all at 0.8"/pixel in M33.... NICE! ... From: Paul Kent To:...
after using the PL39K for about a week, including one night under the stars, I can make a few comments about the usage experience First of all it is a big...
Hey thanks for the usage tips Doug  I knew there had to be a workaround  One suggestion for the deinterlacing: it is a problem to assume a particular order...
Hi All You must be getting fed up with my reprocesses but I have to keep myself sane when the weather is bad. Following tips and comments from various people...

the April issue has an article on RBI that is a derivative work from the paper I presented at the SPIE Electronic Imaging conference in January If you don't...
I did take some more images using the Proline 39K color over the weekend. I started out on Saturday morning in SF and got this shot of the Golden Gate using a...
Hi Richard, Very impressive. Having done a lot of terrestrial imaging myself I can really see that that chip has a very good resolution :-) regards Rainer...
My first post here, I'm very new to narrowband therefore would appreciate your advise for improvement. Captured using OSC QHY8/Ha(4x20m)/S2(23x20m)/O3(6x15m),...
I used the Proline 39,000 Color married to the AP180EDT f/9 again this weekend. That monster refractor has met its match with this monster resolution camera,...
After three(!!) month of being clouded out we are blessed with excellent spring weather for several weeks nowhere in Austria, which gave me the possibility to ...
thart came out really nice Gerhard It reminds me of the very first narrowband image of the Rosette I saw, which was taken by me back in 2003.... At the time...
excellent image gerhard.  What telescope did you use? Was it a fast newtonian, like the ASA astrograph? You have a lot of signal there for four hours  Best...
Thank you, Paul :-) I'm using the 10" ASA, which is just perfect in capturing plenty of information during the limited number of clear nights in central...
Thank you very much, Richard! I know exactly what you are talking about. It was your article in S&T which triggered my interest in narrowband imaging. There...
Yes the ASA caught my eye too. I was shocked by the contrast achieved by a newtonian with a reasonably large central obstruction (to illuminate a large format...
The history of how it happened is sort of a serendipitious one. I wanted an appearance in nebulae I simply could not get with RGB filters and so researched how...
A large central obstruction will always reduce contrast, which can be easily fixed in post processing. The ASA scopes are not cheap, but have been designed by...
