scope monitor
Orion sells a CCD eyepiece which transfers the image to a TV screen. This
got me thinking about a similar setup with a spotting scope for terrestrial applications where high resolution is not too critical. Orion's product replaces the eyepiece, but I'd need something that fits over a spotting scope's fixed eyepiece. If a small CCD head can be found and made to work with a 2" to 3" hand-held TV with LCD screen, a spotting scope could provide a full time display without having to keep an eye glued to the eyepiece. If anyone has tinkered with this idea, I'd sure appreciate some feedback. John |

If your digital camera has a "video out" jack and your TV has a "video
in" jack, you can easily position your camera afocally and see what the camera sees on the TV. I would love to find an inexpensive portable 5 to 9-inch TV with a video in jack to aid with focusing when photographing the moon. The camera's LCD is just a little too small to do this as well as I would like and I hate to haul around a 13" TV for this. If anyone has any TV suggestions I would love to hear them.

They are made for playing videogames in the car and can be found at most well stocked videogame specialty stores and some big box electronics retailers. If you plan to run off batteries and/or in the dark you may want to try replacing the cold cathode backlight with red LEDs. Ian Anderson www.customopticalsystems.com |

Local camping store, local Radio Shack, local Wallmart, local K-Mart,
any place that sells TV's.. I have a small 5" TV that runs on C cell batteries, Comes with a 110 adapter, and comes with a 12 volt adapter and is an AM/FM radio, and has video and audio jacks. It's black and white but it does work well with this Orion video EP. I think I paid $20 or $30. -- Michael A. Barlow "Mark" wrote in message oups.com...

Thanks, but I have looked at the 5" TVs at Wal-Mart/K-Mart/Best Buy and
none has a video input, they only have an antenna input. I haven't looked yet at Radio Shack, but will investigate. If you have a brand name I would appreciate it.

Thanks, this is what I found at Radio Shack in the way of LCD TVs. For
$200, it's a little pricier than I want. I don't care if it's a portable CRT-based TV, but I would like to get it for $50 or less and have the A/V inputs. http://www.radioshack.com/product.as...5Fid=16%2D3013 |

GPX, model number TVP2K. I don't recal where I bought it from
specifically but it was either Radio Shack, WallMart, K-Mart, or one of the sporting stores with a camping department. It has the video and audio "input" jacks and weighs next to nothing. It also takes a lot of C cell batteries but if you have AC it comes with an AC/DC adapter (doesn't have the DC cigarete lighter adapter like i thought). This was manufactured "September 2003" so there's still a chance it's availible somewhere. Another place to look is a camper/RV dealership. -- Michael A. Barlow "Mark" wrote in message oups.com...

In Europe some supermarkets had the 5" Denver B&W CRT TVs on offer for
=A310 ($20). I use one with my Sony P71 digital camera at the telescope using the digital cable supplied with the camera. Great for centering the camera and focussing where the camera screen itself is far too small to see anything astronomical clearly. The little TV was very useful for the Venus transit in quickly-changing cloud cover. Allowing me to choose the best moments easily. I used the fastest indicated shutter speeds to take my 'snaps'. Normally I can hardly read the figures provided by the camera screen. Another supermarket had a 5" LCD colour screen recently for about =A3100. (or $200) But prices are still falling and I'm waiting for something a little larger and cheaper. :-)=20 Regards Chris.B |

Michael -
Thanks, this is terrific, I will look a little more in town and then purchase this one if I can't find it locally. Not a bad idea to have one of these here in "hurricane alley" anyway. Mark |
