Just as a counter example, this was the same system I tried, the Scopetronix,
and I didn't find it working as well as Larry did, but as they say, your mileage may vary. ^_^ -- Sincerely, --- Dave ---------------------------------------------------------------------- It don't mean a thing unless it has that certain "je ne sais quoi" Duke Ellington ---------------------------------------------------------------------- "Larry Stedman" wrote in message ... Howard, I was in the same boat for a while, doing the handheld, which worked okay (heck, I even used a PalmPix, the old Kodak attachment to a Palm, and got some decent shots). Everything I read from users suggested staying away from any device or "platform" that required you to manually line it up with the eyepiece--just doesn't work that well (same problem as trying handheld--getting it lined up right and focal plane set well). I settled on the Scopetronix attachment, which mates the camera directly to the eyepiece. Works incredibly well, costs up to $90 or so depending on camera. I did discover that the first one I got (for a Kodak DX3900) included the standard Kodak adapter for lenses, so one could save some money by assembling things (adapter from camera company, Digi-T ring from Scopetronix). Note also that the Digi-T system works with only certain eyepieces... e.g., generic Plossls, and not with such "beasts" as Pentaxes and Panoptics. Nikons are special... or at least many are, having 28mm lens screw and thereby taking some cheaper Scopetronix solutions. With the Scopetronix and an 8" dob, I got some wonderful Mars pics at the last opposition. Now, focusing is still a bear, so there is still a large % of throwaways. If you have other questions ask away. The yahoo digital astro group is also very helpful. Larry Stedman Vestal |

Look carefully. Yes, the lens has not attachment screw threads because it does
retract after a short while, but on most cameras, there is a part of the camera body that protects the barrel of the lens when it retracts. This part usually has threads on the inside where attachments can screw in. Both my Olympus C-3000 and my Nikon 4300 have this feature, which allows some attachments like filters to be used on these cameras, and it's these threads that allow you to attach these cameras to telescopes via adapters. -- Sincerely, --- Dave ---------------------------------------------------------------------- It don't mean a thing unless it has that certain "je ne sais quoi" Duke Ellington ---------------------------------------------------------------------- "Howard Lester" wrote in message ...

Even if there was some adapter that screwed onto the outside of the camera lens barrel, the lens retracts after about 60 seconds of non-use, and... ouch! |

And while I'm checking, won't you all please check out the fine L.L. Bean blue corduroy shirt I'm wearing: nice threads. Howard |

Dave, always good to have a counter-example!
Just curious what camera it was and what didn't work... One minor problem I've encountered is the ring coming off from the camera and remaining on the eyepiece, wreaks havoc in the dark when you're trying to switch between eyepieces or cameras and what used to attach no longer does! I've learned to hang on to it before unscrewing the eyepiece. Also, the ring goes round and round on my 3900 adapter now... don't know if it got cross-threaded or what, but I'll probably pick up another Kodak adapter ($15 or so). Larry Stedman Vestal |
