I shot a few images in this area in August, too soon for this challenge. Here's another though, which is based around the reflection nebula VdB 152 and the dark nebula Barnard 175 in Cepheus. I gather the Ha filaments across the lower left are a supernova remnant (SNR 110.3+11.3), and there's also the planetary nebula Dengel-Hartl 5 just above this.

It's a two panel mosaic - I wanted the width in order to capture the  long trail of dust (and I don't rotate my camera).

RASA 11 v2, CEM120, ASI2400MC Pro, 236 x 30s (1h 58m) with clear filter, 270 x 60s (4h 30m) with IDAS NBZ dual narrowband filter. Both Ha and OIII blended. Captured with NINA and PHD2 on 28 Sep and 5 Oct, processed in Pixinsight.

Here is another one from me and my take on Barnard 150 The Seahorse. I imaged this on the 29th September from dusk till dawn! I managed just over 8 hours of Ha and LRGB combined, however I have not been able to add the Ha data in without making a mess of things, so this is just 7 hours of LRGB.  I used the William Optics Redcat, ZWO 1600 mm pro and Baader filters. I framed this to include Fireworks Galaxy, The wispy edge of the Flying Bat Nebula and squeezed in NGC6939 open cluster.

here's the Bubble nebula (NGC 7635) imaged last night with my 8" f/4 newtonian, ASI183mm camera on an AP900 mount near Paris (Bortle 7 sky) and with a gibbous moon.

70*300sec H-alpha for the nebula

30*60sec RGB for stars and color

Here's the result with a rather good level of detail (right click for full resolution):



Clear skies,

Here's my elephant to add to the mix. Shot last night in a single night. 9 hours of 10 min subs, with asi2600 and redcat using L-ultimate filter.

forecast yet again proved wrong, and I got clean subs all night. stacked in APP, processed in affinity photo with some starnet2++ and noiseXteminator to help.

<edit - updated to replace with colour stars just imaged)

A try at the ghost of cassiopeia. Not sure I did this justice to be honest. Quite a few of my subs were not great. Even the ones I decided to integrate.  6 hours of 10 min subs with asi533 and L-extreme.

processed in APP and affinity photo. I tried my best to control those stars with limited success I think it's fair to say. But no one had yet posted a hubble type palette, so I figured I'd post.

As I just realised I actually took an image which met the challenge I thought I would share -

This is the Elephants Trunk Nebula

SW 150PDS - Baader Coma Corrector - Canon 500D  unmodified - Mounted on a HEQ5 Pro  - About 1 hr 20min of 30sec exposures & 45min of darks.

Processed with Deep Sky Stacker & Startools

This is the area around Sharpless 2-140 in Cepheus. It was shot in broadband, mostly before the moon came up on Monday (17th Oct). The aim was to pull out the variety of emission, reflection, dust and dark areas in the area, and I needed a 2 panel mosaic to get everything in I wanted to. Starless processing leaves me with some quite large halos around the larger stars, but I've left these alone. 

RASA 11v2 on CEM120, ZWO ASI2400MC Pro, 2 panel mosaic of 103 x 30s and 115 x 30s (total integration 1 hr 38 min). Captured using NINA with PHD2 guiding, and processed in Pixinsight.

Here's another Elephant Trunk.

Data was captured mostly during the challenge start/end dates (precisely 8 Aug 2022 ·  16 Sep 2022 ·  3 Oct 2022), I hope it still qualifies.

Captured in my backyard garden in London (Ealing).

It's also my first picture with my ASI2600MM Pro and Chroma filters.

Struggled with this one, as I spent a week at Kelling in September and a week in the Cotswold's in October and all I managed to get was 1 hour 25 mins lum at kelling and 30 mins RGB in the Cotswolds due to poor weather.,

So this is only 1 hour 55 mins. 

8 x 600 + 1 x 300 lum
4 x 150 binned and 2 each of RGB

ED80 and Atik460EX

The Ghost of Cassiopeia. 11.5 hours of 300 second L-eXtreme subs plus 15 mins of unfiltered rgb subs for the stars. SW 130PDS, HEQ5 Pro, ZWO ASI294MC PRO. Stacked in Siril and processed in Photoshop 👻

Taken on Thursday and Friday night.

Here I aimed my dual-RASA rig at an area south-east of Sh2-140 in Cepheus, and area which looked quite interesting on Aladin Sky Atlas but nevertheless seems to be very rarely imaged. The image reveals that it contains many interesting features including long red filaments. Could they be bow shocks of a unrecognized supernova remnant or somehow pushed out by the stellar wind from the partly obscured star cluster in SH2-140? Since the spectral widths of the NBZ dual-band filter is rather broad I am not sure which of the blue areas are Oiii or blue reflection nebulosity.

Caught 16-17 October. Two RASA8 with ASI2600MC and IDAS NBZ dual-band filter (Ha+Oiii). Sitting on a Mesu 200 mount at my home obsy. 240 x 4 min, so 16 hours. Processed in PI and PS, including Star XTerminator to bring out the nebulosity before adding back the stars.

Cheers, Göran
