I had one like that on my old 12.5-inch Cave Astrola. I had added a nice Byers 11+-inch RA drive, so the scope tracked magnificently. I remember having to understand the wiring output and make my own connectors. I also had the old SBIG ST-4 Star-tracker, one of the very first that worked wonderfully. Honest, I would leave the observatory, and return 2 or 3 hours later, with ONE Exposure on film, tracked to sub-arc-sec! That scope was great for imagery. I eventually sold it off to go onto (Yikes-Bigger!) other scopes Tom
That's an awesome set up and with autoguided film shots! You wouldn't have any pics taken with it would you?
Hi, rolo, yes... many hundreds of multi-hour exposures on TP2415 film. A friend is scanning the negatives now. Some (most?) came out great... for film. Horsehead, Veil, Rosette, galaxies and galaxy clusters... Some appeared in books by Dickenson, Eicher, Berry... Attached a snippet ~quote~ from Terry's |The Backyard Astronomer's Guide| 1st edition, 1991. It occasionally appears for sale here, AMart and can be acquired on AbeBooks website. I highly recommend that original version, nostalgic... pretty much pre-solid-state image capture and plug-n-play autoguiding! GOD, DS imagery was difficult back then! Tom
