The beautiful golden clouds making up part of the molecular cloud in Cepheus, Lynd's Dark Nebula LDN1251. Imaged remotely from Spain with the Takahashi 106ed and asi2600mc pro, Roboscopes Pier 11.. A pretty straightforward process, imaged in OSC 60x 300s totalling 5hours. Processed in Pixinsight and Photoshop.

M1 The Crab Nebula in Sulphur Hydrogen Oxygen and Helium. Imaged remotely from Spain with the 16in Dall-Kirham and Player One Poseidon M-pro . Exposures were 60x 120 in S2, 50x 120s in Ha, 50x120s in O3 and 50x 300s in He2


I really like the addition of the Helium, it brings something very different compared to the "usual" SHO palette that we are so used to with M1.


Although all of the elements show very different structure to each other the He2 seems to have a more diffused look about it.

The Perseus Double Cluster NGC869 and NGC884, surrounded by clouds of Hydrogen. I remember as a teenager stumbling across this with my telescope thinking it looked like a firework in the eyepiece. Such a beautiful visual object, it never really had the same impact for me when photographed. With the added Hydrogen its completely changed the way I look at it. There was some tantalising hints of some faint fluff sitting in the background, I might go back and get a bit more see if I can add to it.

Imaged remotely from Spain with the FSQ106ED in OSC and Antlia ALP-T Ha/O3 5nm. Exposures were 120x 60s in OSC and 70x 300 in Ha/o3. I did a pretty simple process with the OSC data set.


I then set about splitting the Ha from the dual band set and added it to the colour image. I did use a continuum subtraction but it really didn't have much to take out in this case. All of the processing was done using Pixinsight and Photoshop.

M45 The Pleiades. What a wonderful part of the sky, when ever I see it rising in the East I know that the winter of on its way. It still amazes me what can be done with a OSC camera and dual band filters.
Imaged remotely from Spain in One Shot Colour and Ha/O3 Dual band IDAS NBZ UHS filter ultra wide 105 Sigma and the Player One Poseidon-C Pro. Exposure times were 260s x 60s in OSC and 60x 180s in Ha/O3.

This is something I have been meaning to do for ages and combine some H-alpha with RGB. There were always signs of there being enough in the field to make an interesting image. What really surprised me was the amount visible using the dual band and OSC combination.

The Ha/O3 dual band IDAS NBZ UHS filter really brings something quite lovely to M45. I split the channels to create the Ha and O3 data channels that were then added with continuum subtracted techniques so not to contaminate the overall main colour. Although the O3 did contain some signal it seemed to get lost in the RGB data and only create a colour cast that then needed to be corrected out. So I am not sure what benefit it brought in this case.

The Cats Eye Nebula in RGB Ha and O3. Imaged remotely from Spain with the 16in Dall-Kirkham and the Player One Poseidon M-pro...I am really liking this new camera so much cleaner than the previous ZWO with far superior cooling.
Exposure times were 60x 60s in each RGB filters, 240x 60s each in O3 and H-alpha.
Imaged at 1x1 then software binned to 2x2 Processed in Pixinsight and Photoshop.

Additional Info
Anyone who has imaged this one knows how difficult it is to pull out the core detail. Looking the stunning high res-HST image was very useful for reference making it easier to see similarities in the core structure.... I wanted to see if I was able to pull out those beautiful spokes, but honestly I think I was kidding myself to think I could do it with a modest 16in ground based scope. However If I squint my eyes to the point where they are virtually closed and believe like a kid at Christmas sometimes I think there is evidence of them being there!!!
The concentric rings or shells and the knotted jets however are a different story they are quite clearly shown, more visible in the O3 data, virtually nothing in the Ha and only a hint in the RGB. I did take some Helium data but it really didn't bring much to the party so I excluded it from the final image. You have to roll the dice once in a while!
