    Re: TravelWide Repair Question

    TW and replacement parts are now with Mike Hakeem at Professional Camera Repair here in Houston. http://www.professionalcamerarepair.com/


    I may not be able to pick it up for a week or two though.

    Next trick will be getting a GG adapter made from a 4x5 plate holder. The long term plan is to mount the TW on some kind of rail system along with a small telescope. I have rat-holed a "vintage" Celestron C-90 for that project (so "vintage" that it is the old orange color with the larger eyepiece diameter). The hope is to get some 4x5 images with that stacked telephoto look common to smaller DSLR formats. Mountain peaks and such. Maybe some of those enlarged sunrise/sunset type of images too.

    Don't know if I've got a tripod big enough to hold it all down solid at those magnifications. . . .another project.

    Hope it all works out.

    There are only three types of mounting flanges; too big, too small and wrong thread!

    Drew, try y'r C-90 out on a 35 mm SLR before you do anything to mount it in front of y'r TW or (horrors) shoot film or paper with it.

    I make this suggestion because the one I bought in late 1978 to use on a Nikon turned out to be completely unusable. Strong and asymmetrical central hot spot, soft soft soft, and horrible astigmatism, so horrible that it wouldn't focus horizontal and vertical elements of a grid at the same time. Eventually I that the problem was the lens, not me, and took advantage of Celestron's 25 year warranty and sent it back. They sent a replacement that wasn't quite as bad but was still unusable.

    Thanks for the suggestion. I tried it out with my Nikon D-80 a few years ago. Seemed OK then. What a hassel getting the exposure right! The D-80 won't do Aperture Priority automatically with a non-Nikon lens. Maybe it is time to revisit that aspect of the project with a good DSLR.

    Back in the mid 1990s, I lashed together a Bausch and Lomb "Discoverer" spotting scope and a Speed Graphic. Looked like something the A-Team would do if they had to break out of a junk yard. The effective focal ratuo seemed to be in the range of f/22 to f/32 . . .I was never sure. Used the eyepiece projection method and a salvaged shutter (wide open) from an oscilloscope camera.

    Got a few interesting images of the rising sun behind an agricultural wind mill. Got the setting mooln behind a different mill on the other side of the county. I was using the least expensive film I could get and bracketed like crazy as the light was changing quickly. Now, both areas are too built up and the windmills are long gone. The lesson there is shoot it when you see it.

    Speaking as someone who uses the ever-diminishing supply of functional plate holders, may I suggest that you consider doing as Jon Shiu did and just hot gluing a couple wooden runners of the proper thickness to a normal 4x5 ground glass? I have one of Jon's and it works well for me in the Travelwide. Cheap and very easy to do...

    I did that after I found my local Hobby store basswood was close enough in dimension.

    Very easy,
