Hi Jim, I guess I didn't catch this before. So the brightness of the red LED is also adjustable on the Coast lenser? Clear skies, Dale. -----Original Message----- From: utah-astronomy-bounces@mailman.xmission.com [mailto:utah-astronomy-bounces@mailman.xmission.com] On Behalf Of Jim Gibson Sent: Thursday, March 26, 2009 6:20 AM To: Utah Astronomy Subject: Re: [Utah-astronomy] LED suggestions Hi Chuck, I am glad it fits your needs. It is sure helpful to me. It has so many features I like. The brightness is adjustable, tilt to light up subject, duel switches for white/red light and best of all hands free. They advertise a 30 hour life span. I swear I have had mine go longer than that. Of course I use mine on low brightness and mostly the one red led. Yep, it’s a good one. I got my Digital Tracking System back from Losmandy and so I have been setting up all my equipment in my living room. I had to make myself a cheat sheet to be sure I get the procedure down for getting the scope, Canon XT, and Orion StarShoot Autoguider all working together. I have been tracking that street light down the block. So far it hasn’t moved. I have also been building a Dark Library of about 25 dark frames of different exposures and ISOs by temperature in increments of about 5 degrees. Then I make a master dark form those. 25 dark frames should give me 5x noise reduction. The other night before the snow came I set up in my backyard and took some flats. They are throw aways of course, but I wanted to go through the procedure and check out the flats. I won’t be able to do it at a star party because I have to hold up a florescent light in front of my flat mask. I need to get a light box. I am looking forward to putting that parallelogram together. I want to do the Messier list with the 25x100s for starters. I would like to hear what you have to say about the other items you have in transit.
