Are you talking about buying the pulser unit from Perceptor or Efston? If the former, do you know if this is the same unit that Al Seaman described, that is available from Efston? If it is, I'd really

FINALLY! My dewshield has arrived, one month less a day from when I paid for it. So no more hokey toilet paper carton dewshields for me! While I was at it, I treated myself to a Kendrick solar filter

The Perceptor catalogue also has the unit at $29.00. Richard under a beautiful crescent moon!!

Thanks for doing the research, Janice. I might just pick one of these up myself. After reading Al Seaman's comments the other day, I got to thinking, and I think he's right - a push-button on the

I will be in Toronto all next week, and will pick up a Pulsar unit for myself. If anyone else wants one, I could oblige...let me know. Hey, if there were a few, I could probably negotiate a deal!! :o)

It's 21:15, and Aldeberan, a thin crescent moon (with lots of earth shine), and Saturn are beautifully aligned. Add Jupiter to the mix, and you have a lovely configuration. Worth taking a look out a

FYI: I received two replies from EfstonScience (http://www.e-sci.com/) to my inquiry about the flashing pulser unit that can be configured to a telrad. One was from "Bruce" and the other was from

These are two really fine and exciting observations to make. Did you see the vidcam image some guy took of the ISS with only a 90mm scope, in the latest issue of Sky & Tel? This makes me want to try

Thanks, Attilla and Janice. I just did some web surfing, and found a site that shows you how to build the blinking circuit. If anyone wants the reference, just e-mail me. I came across a mail archive

There is an ontario amateur, whoose name escapes me, who has built a blinking circuit for teltrads (variable speed). I had my telrad retrofitted by him at a Huronia Starparty. I suspect he is a
