M31Greetings from the professional and amateur astronomers who comprise the Astronomical Society of Las Cruces (ASLC). The club was formed in 1951 by a group of dedicated astronomers including Clyde Tombaugh, who had discovered Pluto just 21 years earlier. For over 60 years, we've been sharing a little bit of the universe with our community under our beautiful Southern New Mexico skies.

The club has a variety of ongoing observing, education and public outreach programs. We host a public Moongaze each month, offer beginning astronomy courses and support countless star parties for schools, scouts and various organizations. We also hold a meeting each month which includes a featured presentation.

November Meeting

The monthy ASLC meeting will be held on Friday, November 21st in room 141 (Main Branch, DACC) at 7:30 pm. The group usually gets together around 7 pm to talk about 'stuff' and socialize a bit. We'll hopefully approve a 2015 budget and announce prospective officers for next year at the meeting. We have two presentations this month. John Kutney will talk on the visibility and evaluation of deep sky objects (summary below).

Examples will be provided of some deep sky objects that the presenter expected to be easy to visually observe but were non- visible even thru an 18 inch reflector. An explanation of this phenomenon and some tools to measure visibility will be presented.

Following John's talk, the attendees of this year's Okie-Tex star party will share their experiences.

ASLC Photo of the Week - M46 by Chuck Sterling

M46Open Cluster M46 is in constellation Puppis. M46 is about 5,500 light-years away with an estimated age on the order of several hundred million years. The planetary nebula NGC 2438 appears to lie within the cluster near its northern edge (the faint doughnut at the right center of the cluster). NGC 2438 is most likely unrelated since it does not share the cluster's radial velocity, and just happens to be in the same field of view.

The image was acquired from his back yard in Las Cruces, NM, using Images Plus Camera Control 2.0 with a Canon 350d camera on an Astro Tech 8" f/4 imaging newtonian, with an IDAS LPS-P1 light pollution filter and a Baader MPCC (multi-purpose coma corrector). The mount is a Celestron CGE, autoguided by PHDGuide 1.12.3 and a ShoeString Astronomy GPUSB with a Meade DSI-Pro-1 camera on an Orion 80ED f/7.5 refractor.
