Sh2-129 and OU4 (Bat and Squid)

[paulobao]

Hello,

Finally I finished this project started last May!

It is a 8 panel mosaic acquired with my Tak FS102NSV @ 641mm + QSI532WS-M1.

Total acquisition time: 278 hours.

Ha-5nm : 8x 62x15min

OIII-3nm: 8x 77x15min

Processed as RGB.

Not easy to get the OIII signal...again (since I made a squid only version just after Nicolas discovered it back in 2012, and I knew it).

This is version 1 for the RGB/2015.

Cheers,

paulo

Very impressive! Very subtle mix of both narrowband channels. 278h?

Thanks for the comments ☺.

That is very good, and particularly the Squid which is beautifully detailed. But 8 panels/278 hours seems an awful lot!! A full frame CCD at your kind of FL can do this on one panel.

Whatever, congratulations on a really serious effort and a really serious result.

I wonder if you could tease out a little more star colour? I bet it is in the data.

Lovely image and a just reward for all your work. Thanks for posting.

[paulobao]

Thanks again ☺.

Yes Olly, a full frame could do it in single panel or two! But since I only have my QSI532......!

This was try 1! I will try another rgb processing soon (need fresh eyes)! I had problems composing the OIII mosaic and spend lot of time until get it done!

Cheers

Exceptional image of a difficult target.

An exceptional effort but well worth it.

Did you shoot O111 for the whole image? I don't think there's much there apart from the Squid. Or did you find any?

Hello Olly,

Yes, I have the 8 panel too for the OIII signal.

I'm posting both panels (just scaled and reduced in size).

Cheers,

Ha-5nm: 8x 62x15min

OIII-3nm: 8x 77x15min

And the inverted OIII image here (there is some nebulosity around but not that much).

Cheers,

This is a great image - The way that the Squid stands out from the Bat is just amazing.... I wonder if there's anything else out there waiting to be discovered?

All your hard work has delivered a fantastic image - congratulations.

 That is a great image and great detail

Some really nice detail on the Squid there. The OIII image is interesting - the fainter stuff seems to follow the shape of the bat, especially the arm on the right.

Thanks for your interest and kind comments ☺.
