Message: <blockquote data-quote="ostling41" data-source="post: 1420899" data-attributes="member: 62109">I have now machined an adapter to couple the LX3 (with its accessory tube) to the Orion 35mm Ultrascopic eyepiece, which gives a magnification of 36X on the 1250mm (focal length) telescope. The photo shows the adapter in place -- it slips inside the accessory tube, and over the eyepiece, placing the camera at a position which is essentially free of vignetting. The lens is always used at max zoom (60mm with the LX3). The red-dot finder projects a circular target which (coincidentally) is precisely the circular field of view through this eyepiece. I took this photo of an American Avocet this morning, at the Gilbert Water Park. This is almost full-frame, from a distance of about 12 meters.According to the digiscoping calculator (now back online) <a href="http://www.jayandwanda.com/digiscope/digiscope_calc.html" target="_blank">http://www.jayandwanda.com/digiscope/digiscope_calc.html</a> this setup is equivalent to a 2143mm f5 lens.</blockquote>
