..yet another Tarantula Nebula

[Emuhead]

A couple of nights shooting this target, over 10 hours of subs reduced down 7.25 hours of usable subs as the secondary dewed over, which was a first for me.

Quattro 8" f/4, Skywatcher Coma Corrector, asi1600mm, 3nm astrodon filters, eq6r pro mount.

Hope you like it. :thumbsup:

I like it, a lot!

[Emuhead]

Thanks Nik, I'm glad you like it.

I don’t like it, I love it. One of the best I’ve seen. Incredible detail and resolution, well done!

[AdamJL]

Did you take second exposures for the Tarantula core?

edit: ah yes, I see from your Astrobin link:

Total Integration: 71x6m + 18x30s = 7.25 hours

Outstanding effort mate.

Thanks Adam. :D I couldnt ask for more than that tbh.



Actually the 30s frames were only for the RGB stars, the detail in the core is brought out using Pixinsight 'HDR Multiscale Transform' tool. It was there in the asi1600mm 360sec sub at gain 139, just had to be brought out.



Thankyou JA!

Wow!

Beautiful image.

Nice job, strong colour palette, high impact image. :)
Looks like some coma or spacing issue going on though, with slightly elongated stars in the corners at high res. :question:
Overall well done though! :thumbsup:

[Emuhead]

Thanks very much Kanga, Greg, Andy!

Andy, yes agreed, still fine tuning that. Used a 0.5mm shim one night, giving the shapes seen in this image, and removed it to instead use a 0.1mm ZWO plastic shim on the second night, which gave really zoomy shaped stars. Both not perfect. Thats quite a small tolerance, I'm wondering if i had it right on night one but the shape is just residual coma the coma corrector can't correct out. Anyway, have stacked a couple of zwo shims to about the 0.3mm depth to try next night out.

Looks great Andrew. Love the framing and the processing, especially the wispy bits at the bottom.
Didn't realize the 8inchf4 with the asi has a nice wide fov. well done.

Thanks Alistair :thumbsup:. Finally bought a manual rotator and it's immediately a must have piece of kit for me, that and feeling the penny clunk as i worked out asiair platesolve vs telescopius planning both show rotation angle.. a small but important piece of the puzzle slots into place. Obvious after you know of course. Regarding the framing, yes that's the 800mm with 4/3 sensor at work. Wide for some targets, up close for other targets, but i really enjoy that focal length in general.

Cool looking image Andrew, a nice composition too :thumbsup:

Lovely work Andrew. Composition and colour palette working well together
:thumbsup:

[bsteeve]

This looks great! Well done

[Emuhead]

Thanks Mike, maxed out the sensor real estate as best i could.




Thanks Rodney. Might look even better if i had a Tak ;) An FSQ even.




Cheers Steeve!

wow, much 3D detail and well handled dynamic range. I like the pallet too.
I recon using 3nm filters for Ha OII and SII as you have, give the best NB pic result overall, well done!
