I purchased my Pentax 20X60 binoculars last year, and really like them. But I was pretty shaky holding them by hand. Tried a
monopole and resting my arms on solid surfaces so I could be more steady, but wanted something better.
Purchased a Desert Sky Astro DSV-1 mount and Manfrotto tripod in anticipation of acquiring a 92mm refractor in the future. As the
mount was not being used, I decided to modify it to hold my binoculars. I bought an extra dovetail bar($28) and the binocular stem
($3.50) (ebay) and a "L" Bracket from Lowe's ($5.30). I had the hardware already.
The "L" Bracket was trimmed to remove excess weight, and I attached it to the dovetail bar and also put a screw in the bar to keep it from falling to the ground if it came loose. Best balance was achieved by offsetting the "L" Bracket slightly. The system works like a champ and it did not break my pocketbook. By coincidence (?) the opposite side of the mount fits Olympic style weights. I got the 2.5 lb weight from WalMart for about $3.00 and it counterbalances nicely.
The project took only an afternoon with hand tools, and works great for terrestrial. Should be usable for astronomy too when the
objects are fairly near the horizon. Maybe others can get some ideas for their set-ups.
