Window Astrophotography 2019

Post by ivan » Mon Feb 11, 2019 5:20 pm

2019 has been a rather productive year for imaging, with several streaks of clear nights. I received my 3nm narrowband filters about 2 weeks ago, which I had to wait about 3 months as I wanted it fabricated to work at fast focal ratios down to f/3 (due to the bandpass shift at highly oblique incident angles). Thankfully, that wasn't enough to attract clouds, so I could try them out within a couple of days, and I really like the results.

The images here were shot from my home window at Toa Payoh, and are almost exclusively narrowband (except for the horsehead which was a HaRGB composite). All narrowband subs were 15 minutes, while RGB was 90 seconds each. Imaging FL was 585mm.

Image acquisition via Cloudmakers Astroimager, image integration via AstroPixelProcessor, processing via PixInsight.

I may add more data in time to come for some of these objects, but I need sleep for now [smilie=dreaming.gif]

1. Carina Nebula (SHO Palette) - 3h 45 min total integration

2. Tarantula Nebula (HOO Palette) - 3h 30 min total integration

3. Running Chicken Nebula (SHO Palette) - 7h 15 min total integration

And a bonus crop of the Bok Globules:

4. Horsehead Nebula (HaRGB) - Approx. 4h total integration
Image

5. Vela Supernova Remnant (HOO Palette) - 5h total integration
Image

And of course, mandatory equipment shot:

Thanks for looking!

Thanks Chee Yiun! I don't have any plans to work on M42 as yet, but we'll see!
