Excellent video Logan, very informative indeed! Lovely image of WR 134, it's nice to see it in this much detail. I think it looks like a cat fish in most images (especially without the 'gas stove' part being visible).
Thanks very much Pete. I really enjoyed the challenge of this target and discovering that a group had indeed answered the question that I had about the appearance of these WR nebula. And, wow, thanks so much for the incredibly generous super thanks. I'm stunned (in a good way of course). CS.
Moo!!! Great capture Logan & very informative to, your Crescent nebula came out well to one of my favourite targets, Thor's helmet is another nebula that surrounds a Wolf Rayet star WR7 & is one I keep going back to as I'm never happy with the final image. Great video as always clear skies
Thanks Tich. Moo to you too 😂. There is something.... puzzling in my Crescent nebula image and I'm trying to work out if it's real or artefact so it might be the topic of another video at some stage 😉. Thor's Helmet is definitely a favourite too and it's been a while since I've imaged it so it might be time for me to have another go as well. CS
Excellent video Logan!👍I love how your passion for astrophotography is paired with a hunger for learning astrophysics.👍IMHO, thanks are owed for your own oh-so-interesting ode to O-star OIII orbs, e.g. while there's nothing naughty about knotty shells, they're not 'all for naught' ! 😉😁
Thanks Derek and O, I do like your comment 😅. I do really enjoy learning the science behind the targets as I think it makes the image that much more interesting. Unfortunately, I'm no astrophysicist so I just hope I'm interpreting and then conveying the info correctly in an understandable manner. CS
@@LogansAstro Hi Logan! Take it from this retired high school Physics/Chemistry teacher (30+ yrs, and I have the grey hairs to prove it! lol)...you did a really good job of correctly explaining the astrophysics in a manner which everyone can understand & appreciate! 👍👍 p.s. A question: How has the StellaMira 90mm refractor performed for you? Some scopes with the same design have FL53 glass in the objective (e.g. WO FLT91 & a few others), and some have FL51 or equivalent glass. Correct me if I am wrong, but I think the StellaMira belongs to the latter category, so have you noticed any issues to colour error, markedly different focus points for the filters, etc.?
Interesting stuff Logan, so looks like our Dolphin Nebula then would be at an earlier stage with such a smooth bubble happening. Great work explaining how these stars work. Feels like they are very much live hard die young kinda stars!
I should actually say, yes it is 'probably' likely an earlier stage star but as that table graph shows, some WNL ((late WN stars) can have B type bubbles around them as can some WC stars but more commonly it is the WNE (Early WN stars) that are seen with a smooth shelled B type nebula like the dolphin. Similarly, some WNE stars can still have C (clumpy) type nebulae but more commonly it will be the WNL stars. So the correlation is not absolute and they described it as a "loose correlation". I found it difficult to identify which if the WR stars in my images were WNE or WNL stars as they were often just described as 'WN stars' without the early or late qualification. So WR6 (Dolphin head ) and WR134 are both WN stars but I'm not sure if they are definitely E or L types of WN stars. (hope that makes sense).
Great video, Logan. Great lesson in Astrophysics/chemistry. A lot of the time (most of the time) we really don't know what we are actually looking at. This video gives us a good lesson and understanding as why there are different colors and features in the nebulae that we see. Good job. Clear skies
Thanks Pat. If I can learn something about the target I've imaged, I find it very rewarding and it makes the image captured that much more interesting. However, I'm no astrophysicist so understanding all the info and then trying to convey it in a UA-cam video can be a bit tricky 😁. Hopefully I haven't confused people. Clear skies.
Another cracking capture Logan, and sone skilful processing, I love seeing these new targets, and the main combination of Ha and OIII is my favourite…👏🏻👍🏻
Thanks Stuart. This target certainly needed a lot of time on the OIII filter. It looks great in the typical SHO palette but I've always been drawn to the HOO look on this one too. Fortunately Starx played nice with this one and didn't seem to take out any of the nebula (thank goodness). CS
That’s Awesome Logan😀You’ve just inspired me to capture this target! I’ve just finished one with the Esprit at 840, so I’m now going to put the reducer on bringing it down to 650, I’ll be using my 2600mm and 3nm Antlia SHO filters! You’ve set the bar mate, trouble is, I’ve NO idea where I’m going to get 50+ hrs from🤣 Excellent video Logan👍 Great work! Thanks for sharing!Clear skies!
Thanks Simon. It's a great target and you have the right setup for it. I get your point about how to get the 50+ hours on it, given what local weather conditions are usually like but I have my fingers crossed that you get a run of clear nights (although I think your nights are pretty short at the moment being high summer? 🤔). Clear skies.
@@LogansAstro You’re right Logan, high summer! Although we have rain forecast for next week! But at least we are past the 21st (longest day) it’s now getting darker😀 However, it’ll be a while before we see a big difference in the dark nights! This could be a Looooong project 🤣
Awesome shot Logan! 53 hours paid out some dividends with this one. Good info on the WR stars. Would you say that the Oiii dominate ones like Dolphin and WR134 are further along than the Ha dominate ones?
Thanks James. With regards to the OIII predominant nebulae, that's one question that I couldn't quite find an answer to. You might think that a WR star producing an OIII dominant bubble might come from the WC type stars since they have mostly Carbon and OIII but that wasn't specifically talked about as far I could tell and the focus was really on the type/morphology of the bubble/nebula formed as opposed to the predominant signal picked up optically. Something I might have to search further on I think.

Excellent deep dive, Logan! Thoroughly enjoyed it. And of course, excellent images! Well done, indeed.
Thanks very much. It a fun target to image and learn about at the same time. CS
Excellent and very informative video Logan and such a great image! (I also noticed the certificate on your desk) 😉
Thanks very much Nik. Well spotted - that certificate came with some 3nm Optolong SHO filters so I was pretty happy about that.
Looks like a pufferfish to me! Great capture.
Haha thanks very much.
Really enjoyed this video Logan, great images and excellent research
Thanks Tony, I'm pleased to hear that. Much appreciated.
Beautiful image Logan. The information you presented was fascinating!
Best regards
Luis from NY
`Thanks Luis, I'm glad you found it interesting. Wolf-Rayet stars are quite fascinating. CS
Good video, beautiful images, lots of great content to .
Thanks very much Philip. CS
Fantastic image mate. Love that
Thanks very much Glenn. CS

Thanks Ollie. Yep our friendly dolphin would be an earlier stage. And yes, they do indeed live hard and go out with a bang 💥.

@@LogansAstro yes I do prefer the HOO over SHO in many targets, mainly because I find them easier for me to process….😂
awesome vid. instant subscribe =)

Great presentation and great image. better than Bill Nye, the science guy!!
Thanks Jason. Better than Bill (Bill Bill) was what I was aiming for 🤣.
