    Cool Old Venture 76mm Re-Light Report :)



    Sometimes I just get bored.

    Yesterday (Sat) morning, my really cool eighty-nine year old neighbor comes over carrying a bedraggled little telescope, with the bottom of one leg missing, and announces, "Here, I bought you this at a garage sale for two-bucks." It was covered with dust; had no eyepiece; a peg-legged tripod; a pseudo-Eq mount with three knobs missing; the finder had been torn off about a million years ago; and looked like something the cat drug in. It was immediately obvious to even the casual observer that he had over-paid by at least a buck-and-a-half.

    At least it had the focuser and objective opening covered, when I opened the lid the mirror and secondary were clean... thank goodness. So, I thanked him and put it in the corner... having to lean it up because the tripod needed a cane. About two o'clock, it had become a lazy day; temperature of 110o was making it a bit uncomfortable in the pool; and dark skies wouldn't be here for at least seven hours.

    The wife was shopping, and I was bored. What to do? What to do? What the heck, rebuild that little scope.

    Step one: Start the air compressor and blow off the dust and cobwebs. Ah Ha!... it's a Venture 76mm f/9.2.

    Step two: Put a splint on the broken leg so I could work on the scope... simple 1 x 1 "stick" fixed that.

    Step three: Slap a laser in it and see how bad the collimation is.
    This turned out to be an adventure as the return beam was missing the secondary and shining brightly on the garage wall. Time to start at "square one". Install a center dot...Check! Shim the plastic focuser tube because it was wobbling all over the place...Check! Center the secondary and complete the collimation...Check!

    Step four: Put this monster on a tripod. I had a small stainless tripod that would suffice. With a little shimming...Check!

    Step five: Turn this pseudo-Eq mount into an alt/az because I'm not standing on my head to light this puppy. Latitude to ninety degrees and three radio knobs installed on slow motion controls...Check!

    Step six: Install some kind of finder. Digging thru the "junk box", I found a brand new Orion Easy Finder II. Two new bolts/nuts and...another Check!

    About that time (two hours later), my wife arrives with her shopping treasures and asks what I'm doing. Pointing to the resurrected masterpiece, I said, "I just rebuilt this little scope." To which she replied, "You're nuts."

    Finally, dark-thirty arrived, and I was waiting. A quick star test passed with flying colors and I was amazed how sharply I could focus the stars to a pinpoint. Collimation = Perfect!

    I decided that Saturn would be the only object worth testing on his night of so-so seeing. I was surprised when Galileo's "oval star" popped into view. No moons visible and certainly no Cassini division in the rings, but the planet and rings were almost perfect, albeit pretty small.

    If you're still reading, you're likely asking yourself, "Why?" Well, as I said earlier... I was bored. But after going through the collimation process, I gathered a greater understanding of how a newbie who has yet to grasp what we consider basic processes must feel when their new, cheapo first scope can't see anything more than the moon. They're often just plain lost.

    Thanks for reading. It was mucho fun.

    I doubt it. There are three much better scopes than that aren't there.

    Hey the OTA is the same as my little 76mm! Not surprising really. Probably only one company in China makes the things anyway. Great project and great job resurrecting the poor little scope. Mine is currently whimpering in the corner because the dob beside it is teasing an bullying it because it's bigger and it can

    Here's to a great job!

    Wow! Quite a pick-up for $2. It sounds like you've had some fun refurbishing it. Now you have a full gaggle of scopes John. Which scope do you use most often?

    I'll just give it to someone, along with a 25mm & 10mm Plossl.

    I have way too many scopes, three in Florida home. In the desert, my Dob gets 100%. Around home, the 120mm Achro and 150 Newt just about split the duties. Grab-n-go in front yard mostly is a tricked out 90mm.
