Congrats for this new one! The image is really cool!
Thanks Yann!
Stunning! Congratulations.

Thanks Bob!
Congrats for this discovery and the beautiful image Bray !!
Thank you Philippe!
Congratulations on the discovery and thank you for your explanation.
Thanks Joe! Although I must admit my explanation at this point is probably awful
This is really fascinating Bray...congrats on this..
Thanks Niraj!
Stunning. I have a CDK17 in Chile. I'll take a look tonight. I have visibility all night. I'll take mostly O3 but will check for some S2 also.
Thanks Daniel! The CDK17 should return some very interesting filamentary details. I am excited to see!
Bray, I shot O3 with the CDK-17 and got no signal. I checked the coordinates again and they seem to be correct. I'm not sure what the problem is.
Correction. With about 10 hours of O3 I'm just starting to see something.
yeah it will take a fair bit, maybe 25-30hrs for something nice on the cdk
Hi Bray, Congrats on the the very well deserved IOTD. I am still working on the CDK-17 imaging. I have almost 30 hours of O3 and the signal is still very soft. I'll keep going but I'll take at least 50-100 hours to get something worthwhile. At some point we should consider combining the data.
Send me what you've got so far! We may be able to make something from that already. I don't think the FSQ85 data would combine very nicely, but we could definitely do a collab post if you're interested
Yeah, combining with a BabyQ won't be the best. As it turns out, I have one of those in Chile as well. Let me know your email address so I can send you a link to the data.

Great!!!!!The many hours of exposure were worth it. I am flashed.

Thanks Manfed!
Simply fascinating!! I love these types of objects!!
Congratulations Bray!
Congratulations Bray!
Thanks Adriana!
Hi Bray - I'm betting it's a real PN. The hot star is a sdO spectral type, of which are well known to be capable producers of planetary nebula.
The coordinates of that hot star are 01 32 12.6 -49 33 41.1 by the way. Slightly different from the RA and Dec center as presented above.
I see a rough diameter of some 12 arc minutes to the shell.
It's a beauty!

Hopefully I can get some spectra at some point and find out for sure! Thanks Dana
A real beauty Bray! Congratulations! Amazing that something as big as this has gone unnoticed, and can be imaged with a smallish refractor. Maybe it is because it is located in a rather empty part of the sky so therefore not accidentally found when aiming at something known. How did you find it? Were you going for hot stars?
Cheers, Göran

Thanks! I'm too uneducated at astronomy to know which hot stars are good, so I just do a grid survey search.
Really nice capture.
Congrats Bray.

Interesting image. That’s a lot of time in Oiii. Are you able to see it on a raw 600” sun? How did you determine it is 3800 ly away?
thanks for posting
thanks for posting
In a single sub it is barely visible. The distance can be determined from the parallax of the central star, sometimes in vizier the math will already be done and they will provide a distance figure
The presence of Oiii and relative absence of H-alpha is a mystery according to contemporary astrophysics.
In other competing paradigms, the segregation of different elements, different molecules, and different energies is built into the physics. For example, see Marklund Convection as a starting point.

Love the name choice lol. Keep it up Bray, I've loved seeing your work as of late.
Thanks Hayden!
Congratulations - a new member of the club of nebulae! Very interesting and super done!
Thanks Georg!
Well done man. Really cool object and so... random! I like the "the bow shock shape" front created by the star movement explanation... I mean how else could you explain that at this stage!
Thanks Steeve! Yeah I feel like that guy on youtube who says 'you can tell its an aspen tree by the way it is". Really grasping over here
Congratulations on the IOTD!
Greetings Bray Falls,
I dedicate time to photographing potential NP candidates in the southern hemisphere. Thus far, my efforts have not yielded any results.
I am curious about your decision to target this specific location using a relatively small refractor. Despite the exceptional quality of the Takahashi equipment, it is anticipated that discernible features will only manifest after several hours of exposure.
Was your success attributed to serendipity, or did a specific technique come into play? If you are inclined to share your insights, I would greatly appreciate it.
Congratulations on being featured as the Image of the Day (IOTD).

I encountered it while surveying, the FSQ85 image just being a follow-up to the survey! So its mostly lucky, but in a 'make your own luck' kind of scenario
I understand.
Thank you!
Once again, congratulations on the beautiful picture!

Congrats! At 33h of OIII, I'm not quite sure what you put in the category "not crazy faint", though. ;-)
The M31 Oiii arc takes the cake for now! Everything else seems like a snapshot in terms of Oiii integration lol
Wonderful ghastly :-)
How do you gather these incredible long exposure times ?

An exceptionally good observing season this year at Hakos in Namibia!
Nice work !
Thanks Nick!
Amazing discovery! Congratulations!
Nice! Great Job 👏🏽
