I took this over the past few weeks; shooting a bit more when I had the chance. Been a bit busy this year and it is interfering with my imaging L This is a...
Hello Richard, Beautiful image. You used the very long time to get image. I can see the many dark nebulas from your image. Near my observatory the sky doesn't...
Here is another one I shot recently. This is 10 hours total using 15 minute subs, FLI Research Grade Filters, AP155EDF f/7 and Proline PL3200 camera Total...
Another one that's been queued up for posting http://www.narrowbandimaging.com/m20_ap180edt_ml8300_rgb_optec_page.htm it is 3 hours total of 5 minute RGB subs...
Nice set of images Richard, I havent been able to image at all this summer, evertime I get a change its cloudy/raining here and of course while away on travels...
Hallo Richard, It seems that you have been busy lately ! M20 has very nice structures, but maybe you could raise the midtone a bit to give it more 'lustre' (?)...
Thanks Karel I agree with you about Sh2-155.... it is my favorite of the lot... very different in the emission line palette. I very nearly didn't link...
thanks guys. I appreciate all the nice comments from everyone. the IC1396 should have not taken so long: it is the 20% QE of the sensor that makes for...
Hi, After debating about if I imaged a uncataloged PN, I finally decided to process the image of this zone, which is very complicated one, I think. ...
Hi Manuel, This nebulae around this star is not a PN. My friend Franck Bugnet tried to contact Agnes Acker to have a diagnostic and so she said : "Sur l'image...
They are very easy to find using the multispectral tricolor emission line method. Occasionally you may find one that has not been catalogued.. I've found four...
NOT A KAF series.. Just a KAI with electronic shutter http://www.businesswire.com/news/home/20110802005651/en/KODAK-Imaging-Techno logy-Explore-Jupiter ...
Makes sense to use a sensor with electronic shutter for somthing that will give high signal in a very short time span; however, I didn't think it would be that...
I would have thought they would have used a better chip, don't see what is so spacial about the 2020 at least the KAI-4022 same chip much bigger. Rouzbeh,...
I am interested in the KAF09000 as the 12 micron pixels are probably a better match for my 1950 or 2958mm focal length and my local seeing. I know the 09000...
The noise leaked into the system is significant, that's why you need the best cooling. There is some work done both by Richard and myself...but long story...
The flush isn't what adds the noise Greg. It is the charge that leaks out of the traps that does You cannot ignore the RBI in this sensor and you should not...
ment to write 'their' I should have wrote D09 option for enhanced cooling. Anyways talked to the owner of severalapogees, he said they exhibit fixed...
RBI remains an issue with it and deep cooling is absolutely essential for the BSI version. http://www.narrowbandimaging.com/incoming/e2v_4240.pdf if you...
