November 14, 2015

After months of frustration I have finally succeeded in processing an image taken with Richards Nightscape CCD. Most of my issues (OK processing issues :) ) boiled down to the improper Bayer Matrix setting in DSS. Being a DSLR guy the transition to CCD almost had me pulling out what hair I have left.

As you know Richard was gracious enough to loan me this C-14 Edge HD SCT along with a very nice CGE Pro mount plus a Hyperstar adapter and the Celestron Nightscape 10.2 MP CCD camera.

Imaging with this equipment package has been most pleasurable however I had yet to successfully process an image until last night.

Attached are two relatively easy targets that I had imaged back in August. These were imaged at native F11. each image has a total of 21 - 3 min subs and 21 dark frames subtracted to remove hot/cold pixels and the minimal thermal noise. No flats or bias were used.

IC410 Tadpole Nebula




November 14, 2015

Last night was wonderful except for the cold and smoke from wood fires but with Klaus's encouragement I took the image of IC410, the Tadpole Nebula. I think it turned out well. It was very faint. This image shot at prime focus with LPS-V3 filter represents a stacking of eight frames at ISO 1600 to 3200 for a combined time of almost 50 minutes. Froze my buns off!

All of these were shot about 10 miles east of Flag near the Winona ext off I-40, even with Flagstaff being a dark sky city it's well worth taking short trips out for very dark skies for imaging. These images were captured through an Orion EON 130mm telescope, an AP Mach1 mount, and a modified Canon T3i camera, and surrounded by howling coyotes that make sure I'm awake. They have varying amounts of total exposure time, but all are around 2 hours. Image processing was done in Pixinsight to bring out all the detail buried deep in the image.

The Rosette




November 11, 2015

A glorious if rather chilly night, but well worth staying up late to image what has become one of my favorite nebulae, the Rosette. I again used Bill Burke's lovely old Astro Physics ED 6-inch refractor. It's long f/8 focal ratio nicely captured most of this object, with 3 stacked 5 minute exposures at ISO 6400 with my modified Canon 6D. Sometimes things work out just right :-)

IC-405 aka The Flaming Star Nebula in Auriga




November 9, 2015

Last night was another one of those glorious fall nights, with mild temps and an occasional brilliant Taurid meteor streaking overhead. I would have stayed up imaging even longer except for some high smoke that drifted in from a controlled burn somewhere near Flagstaff. Once again I had fun with my friend Bill Burke's excellent vintage 6-inch Astro Physics refractor, with it's outstanding contrast and sharp optics.

This object, IC-405 aka The Flaming Star Nebula in Auriga, is one of my favorite and most beautiful star emission and reflection nebulae. This image is a composite of 3 x 5 minute exposures with the Canon 6D shooting at ISO 6400 and an IDAS LpS-V4 filter. It was then combined with an earlier image taken with my TMB-130 refractor with the same camera and filter. Cumulative exposure is bout 30 minutes.
