Yes Joe anyone under 50 (probably 60) has no idea what were talking about. Think about the things that were built ie Hoover Dam Titanic etc that were all designed using hand calculations and slide

Don Love it – dem’ was the days of real computing, unlimited memory, and engineering hard drive. Yours looks like the famous, highly desired ... K & E Log-Log-DeciTrig-Duplex

Yes the good old days when one had lots of hair with color! Don Anderson

Marj... I think most of us realize it wont be a cookie cutter mod, but well worth the effort and cost. Opposed to the cost of a new mount and of course the biggest advantage... a very accurate

Don, <G> I am VERY impressed. Oh the memories…just like the one that I had. Sigh… Regards, George George Whitney Astro-Physics, Inc. Phone: 815-222-6538 (direct

You mean like this? Don Anderson

Jack and all, The swap out is not an easy one, which is one of the reasons that we have not offered it yet. Yes, many of the components can be reused (motor assembly, worm gear, spur gears), which

I would like to know also; as a new owner of a 1600GTO with original gearboxes, I'm interested. Thank you Roberto

Don, They were only cool if they were full. <G> …but real cool was the slide rule slung from your belt in its case! Talk about a chick magnet…ah, the old days! Regards, George

Roland, will this be a simple swap out for current AP1600 owners. I assume that the existing worm gear would be retained and moved to the new housing for the quick release system. Any estimate on

Had one of those too. Still Have it.Ha Ha. Requires no batteries. Never needs to be rebooted! Don Anderson

Not to be picky, but they are called pocket protectors, and only the slide rule ranks higher in the engineer's kit. Mike

Pen protectors! Wow that goes back a long ways. i used to wear one every day when I was a TV Technician! Back then I thought they were cool. Don Anderson

I switched from a piggyback setup to a side by side setup and I found that it did help with flexure. But I have a permanent OBS so I only had to balance it once. It did take longer to get the right

Mike, I don’t have a definitive answer to that question, but my very heavy (12 lbs. I think) Losmandy side-by-side saddle seems quite solid and rigid for the small but heavy refractors I put on

The discussion about side to side systems has me wondering - Which has less flexure; side to side or piggyback ? Mike

A "teak" is a tiny tweak. A "tiny teak" is a micro-tweak. Let's get these definishions schraightened out! Rolando
