NCG 281 Pacman OSC

[GalaxyGael]

Recent image testing a longer focal length refractor for the first time.

NCG 281 (Pacman nebula).

Captured in RGB (OSC).

No filters.

Backgarden, Bortle 6.

11h (132 x 300s), ASI2600Mc Pro, Gain 100, -10C

Tecnosky 115/800 APO with TS 3" 0.79x reducer/flattener (632 mm focal length at f/5.5) - 1.2 "/px

ASI290mm mini with OAG on GEM45.

Sharpcap v4.0 sequencer, processed using APP and PS (CS5).

 

I tried StarXTerminator on this - will reprocess without using a starless layer for OSC with added stars, some artefacts remain.

Interesting for the amount of 'swampy' dust surrounding and overlying the nebula that is not often captured in NB imaging.

This is a great addition to a typical narrowband target.  Very nice image and well worth the integration.  Lovely starfield.

Thanks. Fewer OSC or LRGB versions of this than I expected, and somewhat clear why its a nice NB target. The stars and the background play a bigger role in broadband to me, although I'll reprocess this in my normal way someday without the starless+stars combination I did here.

That's a great rendition. I love the dustiness that you've brought to this and those browns - extends the interest across the FOV... 👍

A lot to like about your image. Great colours and nice to see all that dusty stuff that, as you say, you don't normally see in the narrowband images.
