I have just finished building a Genesis
16 CCD camera kit, using the Kodak KAF-0401 chip..
I am currently in the initial testing
phase, haveing had only two nights in the observatory to play with it.
The camera's first light was on 16 Jun 2000, fighting moon light, and high humidity.
My target was the Ring Nebula, M57.
Picture Details: 60 Sec Exposure, 1x1 Binnig. 60 Second dark frame
subtracted.
Those round crater like blemishes is due to dust and other cruft in
the light path.
1 July 2000
Last night we finally had some clear sky.
I started again.
Back to the ring nebula to get a better picture.
I took 15 60 Second exposures. I threw
out 5 of them due to tracking errors, and noise. The remaining were processed.
Each picture had a dark frame subtracted,
then they were alighned and added together.
The result:
As you can see, better detail, and depth. I also made sure I got rid of the dust... (The jpg was created by exporting a .bmp from iris, and then converting it. Note that the camera was also also in a differant alignment from the previus session.)
I then tried a dimmer object. M51. Mag
14..
This object is larger than the chip, so
I just worked on the "top left quater". Iris has tools to stich these things
together... I took 15 120 second pictures, selected the 5 best. The result.
Not a lot of cantrast. I played with iris, and came up with the following display. There is a lot of info that is not realy visable when displaying with moncrome displays. I tried iris's "ramp" display... This created...
As you can see, there is a lot of informatuion
there ;-)
The border efects are caused by stacking
pictures that had to be shifted to get them into correct registration.
