Toying with another Roper Scientific camera
      #5720821 - 03/08/13 04:39 PM

I already had the Quantix KAF6303E camera and like it "Very Much", when I ran accross this little Sensys KAF1401E. It interested me since most all of my imaging experience has been with larger sensors(smallest being an 8300 QHY9c). The 1401E is passively cooled but the camera specs show it as being on par with the KAF6303E for the QE graph. It is a camera designed to be used in the same labratory environment as the Quantix.

Trying to reach focus during daytime was a bear since even the shortest possible exposure would reach 4095. I hooked it to my AT65EDQ and after a few try's started thinking "maybe this isn't going to work out"...

In a fit of desperation I took a piece of foil and covered the nose of the scope, took a tiny nail and punctured one hole. I then ran some exposures and can actually see shapes of the trees it's pointing at, and a lot of dust that needs to be cleaned off the sensor window .

I'm hoping to get a chance to actually point it at the sky tonight(now that I know it "is" working)

It was only $150, so if it doesn't work out... what the heck.

I opened the hole in the cover foil to the size of a 16 penny nail... Course after I shut everything down again, I realized that I don't have a UV/IR cut filter in front of the sensor(yet). I have one, just getting some type of focus was all I was hoping for at this stage. I think the aperture is a little small yet to be really worried about filters...

Thanks Chris
I put my 7nm Ha filter on it, and I'm waiting a few more minutes to fire everything up and try some shots. Can't spend too much time unfortunately... work tomorrow. first time in years that I've had to work a Saturday. Yep clear sky.

Got it off ebay. Uses the same data cable and capture card that the Quantix uses so it was pretty painless in that respect as well as the price.

Robert, that's awesome. Does it need a shutter setup like the 3200E chips?

This one came with a shutter already included. Some of them don't have shutters but most of them that I have seen did have them. They are a Uniblitz shutter. I should have some data after I finish getting some dark frames to include in the stack. I'll post what comes out.

I couldn't devote the time I would have liked so my subs were short.

20 X 200 seconds
Roper Scientific Sensys KAF1401E camera. 9 X 5mm, 6.8um pixels
1317 X 1035 pixels
AT65EDQ 420mm Fl
Baader 7nm Hydrogen Alpha filter
stacked in Images Plus with 10 darks, no flats.
I did layer in photoshop to reveal the Trap

For a quick test the details look nice and sharp.

Thanks Warren! Hope to give it a better run on something else as soon as some sky comes my way again. That is @ +10c. I may restack using a different setting and see if I can get more out of it.

Yes Orly it is an NABG chip. I probably could have cleaned that up but It was fun just getting it hooked up and collecting data

It's got to be at least a pound lighter than the KAF6303E.

Good work, looks like a winner! And another project.

Hi Joe! Hey it's actually not too troublesome. I found an old Bell and Howell C mount to M42 adapter so connecting the camera was easy. I sure like the Uniblitz shutter that came on it. very crisp! Snaps Open and SNAPS closed.(almost makes me want one for the 6303E ) Darks are a must with passive cooling. The only real project side that I see is maybe adding an active cooling system . I went back and tried reducing the darks to three and that seemed to work as good as ten did. Of course since the exposures were pretty short the there isn't much to stretch in this data so more exposure is called for. back into the rain for at least a week or more so I'll just have to wait AGAIN!

Hi All,
Just wanted to say hello and that I have several of these SenSys cameras and also the Quantix, collected over years. Much appreciate these discussions and hope to be posting some results later in the springtime!

Regards,
Tom W.
