JSCAS - Sigs

Special Interest Groups (Sigs)


Awards


The Awards SIG (Special Interest Group) is designed to recognize those members who have successfully observed the required objects for the various certificates.

To be awarded a JSCAS Award Certificate, submit your observing log to Triple Nickel. You will need to submit the following: Here are the objectives and rules of the awards program:

OBJECTIVE: RULES: AWARD RECIPIENTS: Thanks for your help with this valuable program. Don't hold back. Please look at the program this way: JSCAS will look more like a force to be reckoned with if we have documented members who have completed these lists. So please, for the club if not for yourself, let me know if you have completed any of these observing lists. If you have any questions or if you have any difficulties with your log, let me know, I really enjoy helping.

CCD Photography

The CCD SIG was established to provide a forum for JSCAS members interested in building or just  using CCD cameras for astro-imaging. There are at least five current JSCAS members who have built their own Cookbook CCD cameras and at least two others who have bought cameras and regularly use them to make images.  This group includes some of the most experienced and published amateur CCD imagers in the world, including three of the co-authors of a recent article in Sky and Telescope Magazine (December 1998) which documented a well-received breakthrough in color imaging, and two of the chapter authors in the recently published Springer-Verlag book entitled AMATEUR TELESCOPE MAKING.  SIG members are always willing to assist others wishing to learn about building, buying, and using CCD cameras and processing the resulting image data.  For additional information, contact Al Kelly at

Saturn by Ed Grafton

This image of Saturn is an"LRGB" taken with a C14 at f/60 using a 10 mm projection eyepiece and a ST6 CCD. Taken from Houston Texas on 11/07/99 by Ed Grafton.

M-17 by Al Kelly

WCMY color CCD image of M17 (the Omega Nebula) made from images taken on 7/25/98 by Al Kelly with a C-8 at f5.6 from Friendswood, Texas. The IR- filtered, cyan, magenta, and yellow exposures were stacked totals of 9, 10, 8, and 7 minutes respectively.

NGC-1501 by Al Kelly

WCMY image of planetary nebula NGC1501, taken by Al Kelly and Ed Grafton on 12/19/98 with CB245 and 32" f4 Newtonian from Danciger, Texas. twenty 15- second subexposures in cyan, sixteen 15-second subexposures in magenta, and twelve 15-second subexposures in yellow were combined with twenty-two 15- second subexposures in white (IR-filtered only).

Observing

The wonders of deep space are open to those with a telescope, binoculars or just plain eyes. Take a tour of the heavens with our monthly Observing program. Visit wispy nebulas, eye-catching clusters, distant galaxies, and solar system objects. Each month objects are selected for your viewing pleasure. These objects will be featured in the Starscan and presented at our monthly meetings. Interesting facts will be given about selected object.
This program/SIG features monthly targets within several catagories; Bright Skies Objects (BSO), Dark Skies Objects (DSO), Solar System Objects (SSO), and Chris' Don't Miss Pick (CDMP). These objects compliment viewers from the novice to the advanced. BSO's are generally viewable from the city, some might be a challange, but are visible. DSO's are generally to dim to be visible in the city. SSO's are just the "locals". Objects which feature the Sun, moons, planets, comets, asteroids, and anything that might be of local nature. The CDMP's are just the object that if you could only view one objects this month, this would br the one.
This SIG should stimulate your observing, and provide objects that can help get you a JSCAS observing certificate! The monthly observing list and awards programs can be found by clicking the Observing Button.
If you need help getting started or need more information on observing in general I would be glad to help you.

Astronomy Fundamentals - Triple Nickel

The Astronomy Fundaments SIG is designed to aid new and veteran observers in the basics of astronomy. There will be briefings covering any astronomy aspect desired, from how to find an object to the latest equipment. The intent of this SIG is to educate all members on those subjects that pose a question to you, the member. So, if there are any subjects you are wishing more information on, let the SIG leader know by email. Past subjects covered were: "How to find an Object;" "Astronomical Measurements;" "Latest Equipment in Finding objects;" "Identifying Constellations and Star Hopping from a Known to an Unknown." Future planned subjects are "Reading the sky in right ascension and declination;" "How to plan and prepare for a star party away from home;" "Collimating your scope;" "New books and old ones to help you observe." The next briefing just might be on the subject you wish to know about, so email your suggestions/questions to Triple Nickel at


Telescope Making

The Amateur Telescope Making SIG was established some years back when Al Kelly coordinated the efforts of about twenty club members in a mass telescope building program. Al designed a telescope that anyone, with just a bit of tool knowledge, could assemble. A second round of construction was started about a year latter and another twenty scopes were born. Several members of our club have produced their own mirrors and are well versed enough to teach others the process. Mirrors from 4.25" to 22" have been made by hand and machine by the more insane of the bunch. Mirror making questions made be forwarded to Bob Taylor.
