Laurin Dave

Cracking image so deep in such a short time. Robin..   I'd say it's the bottom middle panel  that's the 20 minute still mightily impressive though

Really nice Laurin! How do you like the ASI2600mc + 135mm Samyang combination and how have you mounted it?

P

Thank you..  I really like it, goes pretty deep even in my Bortle 4/5. Processing is the key to revealing all that it has captured though,  in particular the Croman tools: Blur, Star and Noise exterminators.  As for mounting,  the camera is supported on a ZWO 90mm  Holder Ring attached to an ADM Losmandy Bar, Lens connection is via ZWO Nikon Camera adapter and the front of the lens is supported by an ADM guidescope ring.   Focus was set in September 2022!

Another Cepheus Samyang135 based mosaic,  this time from the Elephants Trunk via the Bat, Squid and Seahorse to the Fireworks.   8 hours of Samyang135ASi2600mc colour data per panel with the Bat and Squid enhanced using  5.5 hrs of Ha data from GT71QHY600 Astrodon 5nm Ha filter and 12hrs of Oiii data from Askar200ASI1600 Astrodon 5nm Oiii filter.  The IC1396 panel is colour data only.  Data was gathered back in October last year and after several processing attempts over the past year I'm finally happy with it.  Processed in  Pixinsight and Photoshop using the Croman tools

According to Pixinsight the field contains 3x NGC/IC, 8 planetary nebulae, 4Vdb, 16LDN, 95LBN, 3Sharpless and 27 Barnard objects....  I'm not sure whether they all appear on the annotation.

Just viewed it on Astrobin at full resolution and it is just amazing....  so deep in the wings and a 3D effect in the core...  I'd suggest you add the link here

Beautiful image Dave! Love the way you have achieved such a large panorama, whilst dropping in data from more detailed imaging. Something I have read about, but never attempted. Thank you for the inspiration.

A great overview of this fabulous region Dave! I thought the Rotting Fish was called the Guppy Nebula but now I am not sure, could be a name I made up myself when I imaged it.

CS, Göran

Thanks Goran...   whichever one  its called the name is somewhat more descriptive than LDN1251!

Very nice overview of this region! Love it. If I may give a (very small) criticism. The h alpha looks a bit artificial somehow for me, but that's very personal. But overall a superb image!!!!! 

 

Edit: in full size it looks much better probably the compression played it's part on my screen. 

Thank you..  I agree  Ha was the most difficult part to bring out..  its so so faint so lots of NXT masks and brutal stretching required

Dusty Cepheus from the Rotting Fish via the Dark Shark, Wolf's Cave and Ghost to the Iris.  Wide field image based around 3 panels captured through a Samyang135ASI2600mc and enhanced with Ha data from Askar200QHY600 Ha, GT71ASI1600 Luminance over the Dark Shark and Wolf's Cave and GT71QHY600 Luminance and Askar200ASI1600RGB over the Iris Ghost region.   Processed in Pixinsight and Photoshop using the Croman tools. 38hours total integration time.  Annotated version below and link to Astrobin

Most impressive. 🤗 I've done the Dark Shark and Wolf's Cave area separately with my RASA 11, but it's nice seeing them all together.

Alan

Thank you Alan, weather permitting I shall be looking at them again in higher in a months time when we get back form France

Dave

Dusty Cepheus including the Rotting Fish (LDN1251) The Dark Shark (LDN1235) the Wolf's Cave (VdB152)/Ced201/Barnard175), Dengel_Hartl-5 (LBN538) planetary nebula and an ancient supernova remnant. Two panel Samyang135/ASI2600mc mosaic 17.5 hrs total integration time also 10hrs Ha through Askar200QHY600 over the lower panel. But still nowhere near enough!.   Processed in Pixinsight and Photoshop... extensive use of Croman Tools!

Cracking image Peter..  and so many background galaxies

Dave 

Alpha and  Gamma  Cassiopeia plus The Pacman, Breaking Wave and Ghost of Cassiopeia Nebulae and open Cluster M103. Samynag135ASI2600 for RGB, Askar200QHY600 for Ha.  2.5 hrs on each from Sunday night before the clouds rolled in plus some higher res data overlaid lightly to enhance  the Ghost of Cassiopeia and Pacman.  Processed in Pixinsight and Photoshop using the Croman tools..  

Thanks for looking

Fabulous image Olly...  and what a difference the new tools make..  Typo in the title though.. its NGC7129 as per annotation on the TEC image. 

Dave

Having reflected on @gorann 's comment I've done a re-process, less emphasis on the stars and more on the Ha nebulosity... I think its a bit better.

Dave

A great image and you captured it all Dave! Not often seen. I would be tempted to reduce the star field even more with the new XT tools - there is a lot of nebulosity and dust there.

CS, Göran

Thanks Goran... I left them like that as they go some way to distracting from the messy background!

Top job, one of those large “off the beaten track” galactic nebulae done very well! Are you looking for other neglected sharpless objects?

Peter

Thanks Peter... as for other Sharpless objects, not especially, I started this back in January whilst waiting for Orion to clear the roof tops as an experiment with the Samyang...

Does star exterminator work on color data or per channel? This is in red channel only.

Afraid I don't know Vlaiv

Very nice Olly...  I had a feeling that you' chaps would be doing this region   ..     Vlaiv  the artefacts are I suspect from Star Exterminator, Olly, did you use the large overlap option? I've found that this option minimises them  (although takes absolutely ages)  and that they appear more readily when the integration time is short.

Dave

A very good start, your bright (and not so bright) stars are saturated so I'd lower your exposure to 30s to start with and see what happens . How do you focus ?  If you haven't got one I'd suggest using a Bhatinov mask.
