Default Best Current Camera for Digiscoping ???

For those that want ot know:
Nikon 995
Scopetronics Maxview 18mm
Celestron 80mm f5 Wideview refractor

ABSOLUTELY NO VIGETTING through the ENTIRE zoom range.
That is the standard I am looking to meet.

It is my belief that the Nikon CP9xx/CP4500 has been the defacto stadard for digiscoping. Nikon has discontinued this product line. In my messages back and forth with Nikon USA, it appears that Nikon has no interest in pursueing this market. So my question is:

What is the best current production camera for digiscoping ??
or
Where do we go to from here ??

Hi LewTwo,

I believe the 4300 is still on production. I tested one and it gave identical results to my old 885 so I kept the 885.

I see you have a ST80. How good is it for digiscoping? Isnít chromatic aberration an issue with the short tubes? I just bought an Orion ST80 (Identical to the Celestron) for astronomy, but Iíd be delighted if I could use it for digiscoping.

Thanks

Actually the BLUE ring around a bright moon is kind of interesting.
Stopping it down (using the lens cap) seems to help.

For Terestrial puposes it does not seem to be a problem.

Well In answer too your question here is one shot throught a Celestron Comet Catcher (500mm f3.65).
http://www.keywild.com/moonshot/1.jpg

and another throught the celestron Wideview (400mm f5)
http://www.keywild.com/moonshot/2.jpg


These were both taken with the CASIO SV8000 and a Williams Optics 43mm eyepiece at f8 maximum zoom. I neglect to set the white ballance. Like I said I have real hard time getting the focus right.

I slos have not figured out how to imbed a JPG in a message here.

Cool, thanks for sharing.

When you say "For Terrestrial purposes it does not seem to be a problem." you mean digiscoping or simply looking at the eyepiece?

I have the Orion ST80 which is equivalent to your wideview. Iím interested on digiscoping birds more than anything else.

If you check the web, you can still find CP990's, CP995's & CP4500's.

Unfortunately, there are no new digicams which come remotely close to these for digiscoping. The trend is toward larger, faster lenses and toward more optical zoom. All these factors work against the digiscoper.

Best regards,

Lin

My conclusion as well.

I put a similar question to the peons at Nikon USA .
They came up with the company line ... that is to say ZIP.

I was hoping someone (anyone) would prove me wrong.

I suggest trying one of the current internal zoom cameras, such as the Minolta Xt, Xi and X20 or the Pentax Optio 33WR. Recall that the discontinued nikons were also internal zoom cameras, and this was one of the primary features that made the nikon line so successful. To couple the camera to the scope, you will need a universal adapter (offered by scoptronix and orion). I have not tried these cameras myself, so this advice is speculative but if there are any members out there who have tried these cameras, please let me know.

I would go with the Nikon"s. Ive got a friend who's got one and I've tried it myself and the results are great. I myself am using a Sony CD400 coupled to a Pentax 80 Ed spotting scope via scoptronix adapter. The Pentax uses the same 1.25 eyepieces as telescopes. The eyepiece that I've had the most success with is the Orion Highlight plossel 40mm with virtually no vignetting, but I just ordered a superwide eyepiece just to see the difference. Has anyone tried one of the Orion scopes with a 2" eyepiece yet or should I be the first?
