Original model DSI
by Dave Gary 04 Dec '12

04 Dec '12

Dan, Yep, the original model DSI. It seems to work with the Macbook Pro using Nebulosity 3.0. I don’t have to launch the Windoze emulator to run this camera. That’s nice for me as I’m a Mac fan. I found the camera stuffed out in the garage, yesterday, and thought I might give it a try. I’ll work with it some more when I get the time. Probably, near the end of December. Dave

Money in the Hole
by Dave Gary 04 Dec '12

04 Dec '12

Larry, I’m glad you got the wifi unit to work. Too bad neither of us are “rich beyond the dreams of avarice”..can’t remember where I heard that one…or we could just buy a nice observatory and have someone teach us how to run it. As it is, I’m doing the same as you. Buy a few things here and there, try to learn how to use them and not go crazy trying. For some reason there seems to be a very steep learning curve associated with all this astronomy stuff. My learning processor seems to fade with each passing day making life more difficult with all this image processing to be done. How to stack, how to drizzle, the list goes on and on. I need some kid around to show me how all this stuff actually works…sort of like when you try to hook all the components up on your new TV or sit staring at that brand new cell phone. Without the kid you’re watching the old TV in the bedroom and all those bells and whistles on the cell phone don’t mean much because you just open it to answer and close it when you’re done. Of course, I hate phones. Dave

Jupiter ~ 20:00 MST 3 December 2012
by Dave Gary 04 Dec '12

04 Dec '12

Image of Jupiter I took last night with Meade DSI. The post-processing was that I made the image black-and-white. One of these days I’ll learn how to use Nebulosity as it was meant to be used. Dave http://www.flickr.com/photos/78046474@N06/8243772240/in/set-721576321678901…

Voyager and MSL
by Wiggins Patrick 04 Dec '12

04 Dec '12

For those wanting to listen to recordings of today's Voyager and MSL media telecons at JPL: http://www.ustream.tv/new/explore/technology/all?subCategory=technology-sci… Also, while flying back from the Fillmore area today I happened to catch the setting Sun reflecting off a long, sinuous river. Unfortunately my picture does not do it justice but to the eye it reminded me of some of some pictures I've seen of large rivers as seen from space: http://users.wirelessbeehive.com/~paw/temp/river.jpg patrick

Explore Scientific Eyepieces
by Debbie 03 Dec '12

03 Dec '12

Hi, Has anyone viewed through a 24mm 82 degree field eyepiece? I'm thinking of getting one since my weight limit for my scopes is 1.6 lbs. I don't think I can afford the 22mm Nagler since I have other interests taking my time and money. A bit balmy down here so we will enjoy it while we can. Debbie

ATM report for the 12/1/ session
by Hutchings, Mat 03 Dec '12

03 Dec '12

Charlie, Josh and Mike attended and made the ATM session on 12/1/12 a fun one. Charlie made a tool to work his 5 5/8" mirror blank on his machine. The tool was made of dental stone and marbles. He chose to use round marbles as the very small initial contact point of the marbles will more quickly grind into conformance to the already generated curve of the blank. We welcomed first time attendee Mike Wilson to the garage and were duly impressed by his interest and enthusiasm for ATMing. He is in the process of acquiring a kiln which he plans to use for blank making. Casting, slumping and annealing blanks are some of the things that he is planning on doing with the kiln. Josh used his bath interferometer to test an 8" mirror I recently have completed. We got good experience in getting good images of the fringes and using the program "open fringe" to evaluate the in 'grams. Josh and I will provide training on using the bath interferometer to my ATM mentor in February, so we are spending time getting ourselves proficient with this tool. Thanks to the attendees for making this a great session! Mat This message and any attachments are solely for the use of intended recipients.
