A reminder of last Summer - Crescent Nebula

[James]

It's been a long time since I've been out imaging (until this week only once since Kelling in September ) so I've got some images to finish off. It was clear last Saturday and Kate took the kids of my hands and let me go out whilst it was getting dark so that I could get some more data for the Crescent which is rapidly setting in the west now.

The Crescent (NGC6888) is an emission nebula in Cygnus and has been formed by a collision of material from a red giant and stellar wind from a nearby Wolf-Rayet star creating two shockwaves.

The image below consists of:

15x 10min Ha

4x 10min OIII

6x 15min SII

Captured over several sessions over the last 6 months I'm going to add a lot more OIII and SII but I think it'll need to be done next summer now... I also need to work on the guiding as the 15 min SII subs showed a little trailing.

Mount: EQ6 Pro

OTA: Megrez 72

Guiding: ED100, DMK31 with PHD

Imaging: Starlight Xpress H9, Baader Narrowband filters

Captured using Nebulosity

Stacked and processed in PixInsight.

As always comments (especially critical) are always welcome.

No critical comments James, it looks superb. The narrow band treatment is really working well on the crescent.

No critisim here either, a very nice image!!!!

Very nice, managed to get detail across the entire nebula.

Imaged this earlier in the year and there is defiantly an interesting outer shell in OIII

Way to go James

oooh, missed these while away. Very nice James, good to see you narrowing out, if that makes sense

...good to see you narrowing out, if that makes sense

Only in terms of imaging unfortunately

A fine image you have there James, excellent detail.
