M57 with Ha

Posted By Joe Gafford
Here's an image of M57 I took this past summer (at RMSS) with some Ha info acquired this past week with the new filter. 18" f4.5 Newtonian with ST-2000XM ccd camera with Astrodon LRGB filters and an Orion Ha narrowband. 20/50/20/20/20 minutes LHaRGB. Enjoy!

M51 from this morning

Posted By Joe Gafford
Jose, very good! Attached is my version I took a week ago at my club's dark sky site (near Deer Trail in eastern Colorado). JMI NGT-18" f4.5 telescope with field flattner used. ST-2000XM ccd camera binned 2x2, 10:10:7:10 minute LRGB respectively. Seeing was fair, good transparency, chip temp: -25C, outside temp: 9F. Processed using both CCD_Soft and Photoshop Elements 3 with FITS liberator plug-in. Jose, I noticed that the image is backwards due to the use of the Photoshop. Flip the finished image vertical before saving to get the proper aspect.

TSP Report

Posted By Joe Gafford
All, this was amongst the coolest weather TSP has had. cwy I managed to get a few images done and a new asteroid confirmed on the site. On Thursday morning after the storm passed, I managed to get a fair image of Seifert's Sextet, a galaxy cluster in Serpens.
On Friday morning, I aquired, took images of, and sent data on asteroid 2005 JQ5 to the Minor Planet Center all within one hour. This is the first time asteroid data was sent from the Prude Ranch since 1998. 8) Joe.

Image data: NGC6027, Seifert's Sextet.
Telescope: JMI NGT-18, 18" f4.5 Newtonian.
Camera: SBIG ST-2000XM.
Exposure: 10, 10, 7, 10 minute LRGB respectively.

Help with Long Exposure.

Posted By Joe Gafford
Paul, first you need is a occulting spot or bar in the prime focal plane to blot out the planetary disc. This is true for the gas giants as well. This is usually mounted inside a special or modified eyepiece and uses eyepiece projection. A bar is easier to construct and is usually a tiny strip if blackened metal mounted in front of the lens elements of an eyepiece that has the focal plane there. You may google around for anybody doing the planetary moon spotting. Joe.

Looking for ticket to Winter Star Party Florida

Posted By Joe Gafford
Elisa, try to advertise in the Astromart Classifieds under 'Misc. and other astronomy' for your ticket. If you get an offer, contact the WSP organizers so they can validate your ticket. It is a pass to get in the gate! 8) Joe.
