Marius Hills dome complex 2008-05-17 Ealing
by Canopus56 17 May '08

17 May '08

In the past, uber imager Jim Phillips' low-sun angle images of the Marius Hills dome field have often inspired me. Although taken at low-image quality and poor seeing, I couldn't resist attempting my own picture of this facinating region of the Moon: Marius Hills 2008-05-17 06:30UT http://gallery.utahastronomy.com/main.php?g2_itemId=11289 Misc raw image 1 http://gallery.utahastronomy.com/main.php?g2_itemId=11293 Reference image - USGS shadow relief http://gallery.utahastronomy.com/main.php?g2_itemId=11291 Reference image - Lunar Orbiter II-M213 http://www.lpod.org/archive/LPOD-2004-08-28.htm Like the Mons Rumker, there is some apparent, but uncertain, association between the volcanic dome field and wrinkle ridge feature. - Kurt Fiducial amateur images JÃ©rÃ´me Grenier 11/23/2007 http://www.lpod.org/?m=20071123 Jim Phillips 4/28/2008 http://the-moon.wikispaces.com/LPOD+Apr+20%2C+2008 Jim Phillips 5/22/2006 http://www.lpod.org/?m=20060522

C. Babbage crater ray 2008-05-16 Ealing
by Canopus56 17 May '08

17 May '08

This is a low quality, poor seeing image of a crater ray entering C. Babbage, a 143km dia. northwest limb crater, taken 5/17/2008, 5:30UT. C. Babbage http://gallery.utahastronomy.com/main.php?g2_itemId=11281 Reference image - USGS shadow relief (LTVT aerial) http://gallery.utahastronomy.com/main.php?g2_itemId=11283 Misc. raw image 1 http://gallery.utahastronomy.com/main.php?g2_itemId=11285 Misc. raw image 2 http://gallery.utahastronomy.com/main.php?g2_itemId=11287 About three hours after this image was taken, Babbage looked more like Colin Evan's image, below, except that Babbage A (dia. 32km, depth 1.4km) occulted the Sun, casting a dark bar shadow across the crater's floor. This created an analogous inverse light-shadow pattern seen in my image above. The height of Babbage A's rim is not known. No high-skill amateur image of Babbage in a crater ray event was found in LPOD or Coppermine. Crater rays - that result from lunar sunrise piercing through gaps in crater rim walls - are some of the most visually dramatic events to observe on the Moon. A crater ray opportunity database, prepared by the Robinson Lunar Observatory (Kansas, USA) can be found at: http://www.lunar-occultations.com/rlo/rays/rays.htm - Kurt Fiducial amateur images By Mark Crossely 4/2006 http://lpod.org/coppermine/displayimage.php?album=4&pos=3 By Colin Evans 1/2007 http://lpod.org/coppermine/displayimage.php?album=4&pos=2 P.P.S. - Around 2:00am at a near full Moon, as I was closing the Ealing SPOC up, there was knock at the door with the voice - "Is the observatory open?" Turned out to be three Argentinian's with a Christmas Bushnell GOTO Northstar 90mm Mak and a copy of Skywatch. Good group of young guys in their mid-20s. They showed up intending to look for galaxies. Spent a couple of hours showing them the basics of GOTO scope setup, visual limiting magnitude vs. magnification and sky brightness. They intend to show up for next Saturday's SPOC public star party. If someone sees them, please take them under your wing.

CNC supply experience
by Howard Jackman 16 May '08

16 May '08

Hello, I was wondering if anyone has had any dealings with CNC Supply? http://cncsupplyinc.com/ They seem to be Scoptronix renamed! I'm interested in the Digit-T set-up to start taking pics with the new camera. I sent them an email and they replied within minutes but I'm a bit leery about giving money to companies that have to rename themselves. Any input would be welcome. Thanks Howard PS I've bought from Scopetronix in the past and never had any problems, I just read today that they'd closed but the website's still up

Misc low quality images - C J Herschel
by Canopus56 16 May '08

Some poor-seeing images of C. J. Herschel north of Sinus Iridium taken last night with the Ealing, 2008-05-16 6:06 UT: C. J. Herschel http://gallery.utahastronomy.com/main.php?g2_itemId=11273 Reference images - Shadow relief and Clementine http://gallery.utahastronomy.com/main.php?g2_itemId=11275 Misc processed 1 http://gallery.utahastronomy.com/main.php?g2_itemId=11277 Misc processed 2 http://gallery.utahastronomy.com/main.php?g2_itemId=11279 Even in the low quality images, the key morphological featurs of this crater are hinted at: 1) raised convex dome-like crater floor 2) hummocky ejecta from the Imbrium impact 3) possible buried floor fracturing Cameron lists this as a ring dike crater, but I don't see it that in my low-quality, the reference or the fiducial amateur images listed below. - Kurt P.S. - Fiducial amateur images of J.

Off-Topic: Canon camera users running CHDK
by Howard Jackman 14 May '08

14 May '08

Hey everyone, sorry about the off topic post but I recently bought a new Canon point and shoot, the A720IS. I discovered during my online research that a open source code for Canon cameras exists that allows these little point and shoots to do some amazing things. I've installed it but was wondering if anyone on the list is familiar with it? It's called CHDK I'm particularly interested in the manual exposure overides and the timelapse and "lightning" shots that this will allow, seems to have a steep learning curve and I'm impatient and wouldn't mind having a local guru to help out. Thanks! Howard

M101 Luminance - aka. All-Nighter!
by Tyler Allred 13 May '08

13 May '08

Hi all. I took most of the night on Monday collecting luminance data on M101, and really managed to capture a lot of the dim portions of the galaxy. I ran the camera at F/3.3 for 4 hours and 10 minutes on this one, just collecting the luminance data. I will try for color soon, but I am pretty happy with this for now. Here is the link: http://www.utahastronomy.com/main.php?g2_view=core.DownloadItem <http://www.utahastronomy.com/main.php?g2_view=core.DownloadItem&g2_itemId=1 1211> &g2_itemId=11211 BTW - Does anyone know why my middle sized versions don't show up on the gallery? Every time I upload now, I get a thumbnail and the full size versions, but the reduced version shows up as a blank. Any ideas? Thanks, Tyler _____________________________________________
