IC 1396 - Elephant Trunk Nebula - Reprocessed

[EyeGuy]

This was 3 night's work with a Takahashi Sky 90 on a self-guiding Vixen SXP mount from the back yard. I used a triad filter on a Canon EOS Ra at ISO 800.

157 x 5 min subs = 13 hours integration time (my longest yet by far)

Processed in PI and PS. I drizzled again (sorry Vlad - I just can't help myself) and was pretty happy with the level of detail from a 407mm FL.

The wide shots show a fair bit of astigmatism in the corners - but I thought the Sky 90 did pretty well. The Vixen SXP is a dream to use - it's lovely to be able to do the entire thing without a laptop. Annoyingly I had the mount in the wrong mode (Dec off) for 2 nights so the stars are a bit eggy, but I didn't have the heart to throw out the data.

I think the smallest crop is a bit reminiscent of the dementers in Harry Potter.

* Edit - I had another go at reprocessing this. I think I left the originals far too muted. I redid them as LRGB, with the red channel (HA really) as the luminance layer).

Thoughts anyone? Better before of after?

Some lovely detail showing up and well balanced colour.

Really great images of one of my favourite subjects. Well imaged and finely processed.

Thanks Steve. It's a real treasure trove of objects. What do you think of the reprocess? Better / Worse?
