Gianluca,
Congratulation, that is a very impressive image, not to mention the detail. I am not familiar with the filters you mentioned, only the Coronado scopes. If and when you have the time, can you take a picture of your set up? I would like to know more about it. I am also confused about the 46mm clear aperture you mentioned and you are using it on a 180mm TEC? What am I missing?
Sincerely,
-JW:>)

Steve,
Very nice shot ... hope you don't mind but I sharpened it just a touch.

Nice image Jim,
I wasn't able to find this particular camera on-line, only as a kit IF (notice the if) I recall correctly. Is there an equivalent camera to the Artemis285 available today that has the same characteristics?
Thanks in advance,

Optical engineer(?) photomultiplierPosted By James Witt |
Larry or ...
Here is an interesting article ... more towards the end (much of which is over my head) ... for example:
...... The resolution of the spectrophotometer is governed partly by the quality of the grating and partly by the width of the slit in front of the photomultiplier. A narrower slit samples a narrower band of wavelengths in the spectrum the grating casts across the slit ......
