Window Astrophotography 2019

[ivan]

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

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


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


And of course, mandatory equipment shot:


Thanks for looking!

Nice imaging Ivan! Will you be working on m42?

[ivan]

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

Excellent Ivan, and i like your Horse Head neb very much

[ivan]

Thanks Peter!

I've managed to add a couple more hours of OIII and SII data on the Running Chicken, totalling 9.3 hours so far. I've also handled the stars a little more carefully in the processing this round:



Full FOV


There is a little-known planetary nebula near IC2944, which I happened to notice while processing the images. It is designated PK 294-0.1, and lies about 5 arcmin NE of IC2944.

Haha, don't think I'm deserving of that title, but thanks Kochu!
