Lasers!
by Seth Jarvis 20 Jun '08

20 Jun '08

The new laser from Destructive Gear arrived this morning! The test sheet accompanying it says its mean output during the 20 second bench test measured at 114 mW, even though it's sold as a 100 mW product. Is it noticeably brighter than the 80mW laser I just sold to Wayne? Hmmm... that's a tough one. If/when you folks have a laser shootout, I'd be interested in participating, or at least receiving a report on the event. Thanks, Seth

Sticky grease?
by Canopus56 20 Jun '08

20 Jun '08

I am rebuilding my Orion right angle finder to make it more accurate and enjoyable to use. The finder scope is fine, but the holder is some ill-designed, bad-manufactured nightmare that flops a good 1/2 to 1 degree after a meridian flop. Having fixed the play in the holder, I would like to make one more improvement to the cross-hairs of the right-angle finder scope. I prefer to align my finder's cross hairs along the RA and Dec orientation. That simplifies moving the target object into the center of the crosshairs using a handcontroller. The target moves left or right or up and down parallel to the crosshairs depending on which handcontroller buttons are pushed. This aids moving the target into the TFOV of the observing eyepiece. Since the finder is a right-angle, I cannot simply rotate the entire finder body. That moves the finder eyepiece to an inconvenient position. What I would like to do is to rotate the finder's combined eyepiece and cross-hairs by having the finder eyepiece adjustable. It only needs to rotate at most 90 degrees. Right know the finder eyepiece is designed to screw home to a fixed immoveable position. I was thinking, rather than drilling and taping a set screw, that I could just use some sticky grease to increase the "sticktion" action on the finder's eyepiece. That way I could rotate the finder eyepiece to the right orientation and have it stay there. I have seen such "grease" on other parts of telescopes. It is a very thick grease-like substance that does not change viscosity much with temperature. What is the material that I am looking for? What is it called? Where can I buy it? Or am I imaging that "sticktion" grease exists as an ATM material? Or is there another simply solution that does not involve my die and tap set that I have overlooked? Thanks - Kurt

OK, OK. It SEEMED like 75 Watts, but yes, I stand corrected. In my haste and enthusiasm I forgot the "m". By the way, I just purchased a two pack of CR123A batteries for it at the Walmart in Riverdale for $10.50 including tax. Wayne A.

That's what's so incredible about the laser. How bright such a small amount of energy can be if it's coherent and collimated. (IIRC, Seth said your laser is actually rated at 80 milliWatts.)
