Goosehead Nebula in IC 1848 (Fall 2018)


Here's a Hubble palette Goosehead Nebula from IC 1848. Data for this image includes, for H-alpha, 20x1200"; for OIII, 16x1200"; and for SII, 17x1200". Camera was the SXVF-H9, telescope the Synta-ONTC f/4.95 Newtonian. Some of the Ha and SII were taken with the moon at >60%. Below is a more natural color version crafted from the same narrowband data.

Centaurus A Galaxy (Fall 2018)

Here is the latest data from New South Wales.  This has been fun to work with, and I've learned a lot.  If you know where to look, you can see the jet from the active galactic nucleus streaming down and to the right of the center.  I was surprised to see it, but the 12.5" RC did a nice job picking it up. Of course, this galaxy can be imaged from Texas, but not well.  It is a much better target from Australia.

The Wizard Nebula and NGC 7380 (Oct. 2018)

Here is another target shot while waiting for other things to rise.  This is 11x1200" with the SXVF-H9 through the Synta-ONTC 8" and an Astronomik 6nm H-alpha filter.

Bubble Nebula, NGC 7635 (Oct. 2018)

Here is another Bubble Nebula, a target I've shot many times, but I had some time before my primary target rose, so why not?  This is 14x1200" with the SXVF-H9 through the Synta-ONTC 8" f/4.95 and an Astronomik 6nm H-alpha filter.

Comet 38P/Stephan-Oterma, 9:52:06 t0 10:18:21 UT, 11-03-2018

About the time I meant to stop imaging on Nov. 3, 2018, I noticed this comet on the SkySafari map and that Gemini, the comet's current location, was near zenith.  This is 24x60" of the comet through a CLS filter in front of the SXVF-H9. The telescope was the Synta-ONTC 8".  I could see the comet move between frames, which was pretty neat. The comet has an orbit of 38 years, so if you are >50, like I am, you may not want to miss it!
