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 Dave

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! Dave Thanks Olly, much appreciated Dave

Thanks Pramod

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. Image, annotated version and link to Astrobin below Thanks for looking Dave Cepheus Mosaic:- The Elephants Trunk, Bat, Squid, Seahorse Nebulae and Fireworks Galaxy ( Dave Boddington ) - AstroBin

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 Dave

Thanks OldEyes Thanks Peter Thank you Olly.

Wow... amazing! Dave

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

Thank you Michael Thank you [paul Thanks Simmo Thanks Chris 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 Thank you Carole.. I hope you enjoyed it ! Thank you Thank you Thanks Steve...

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 Thanks for looking Dave Cepheus from the Rotting Fish via the Dark Shark, Wolf's Cave and the Ghost to the Iris ( Dave Boddington ) - AstroBin

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! Thanks for looking Dave

like this one. perhaps... be great from a dark site such as yours Olly

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 Dave

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

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

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... Thanks Peter... one for Pier 5 perhaps? Thanks Steve...

SH2-126 The Great Nebula in Lacerta. 8 hours each of Samyang135ASI2600mc colour data and Askar200QHY600 Ha data. Data capture started in January with another short session in mid July and finally 5 hours last night. Processed using Pixinsight, Photoshop and Russ Cronan's Star and Noise Exterminators. Presented at 75pc Thanks for looking Dave

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.

ive pm'd you the text
