NGC 2070 Tarantula Nebula Re Process

[Startrek (Martin)]

It’s been nearly 2 years since I’ve imaged this object with a decent amount of data. This image was data from January this year when due to clouds, I only captured 10 subs and not long after that cloudy weather and rain continued. So never managed to capture anymore data on this object.

South Coast NSW
NexDome
Bortle 3 skies with a 50% waxing moon
My old 8” f5 GSO Newt
EQ6-R pro mount
ZWO2600MC. Cooled to -10C. Gain 0
Optolong L Extreme filter
10 x 3min dithered guided subs
No calibration frames
Stacked in DSS ( average )
Processed today in Startools V1.8
Compose Bi Colour OSC
Colour mapping matrix - used SHO
Colour Style Scientific

Bit noisy but happy with the level of detail for only half an hour and no calibration
Heavy crop to remove the Vignetting

Hope to image it again this summer, but this time with my 10” CF newt and loads more data ( if the weather is kind to us )

Comments welcome
Thanks

Hi Martin

My favourite nebula!

I think the central portion of this shot is one of the best of this nebula that I've seen. Lovely effort with the core

As you say, the rest is a bit noisy/mottled, but that core is outstanding.

you need to start posting bigger images! Get yourself an astrobin account, or host them somewhere yourself

Great outcome. I thought for a sec you already got your narrowband gear

[pkinchington (Peter (Kanga))]

lovely image!

Thanks Adam, John and Kanga
Obviously the main body and core of the Tarantula has plenty of depth and brightness in order to allow ST to work its magic, whereas the outer regions due to only 10 subs had a very high noise floor. Stacking only 10 subs really doesn’t boost your SNR a great deal , 60 to 100 + subs an entirely different story.
Spatially Variant Deconvolution ( SV Decon ) an entirely new concept / module in Startools V1.8 worked beautifully in the main body to sharpen up the fine detail including stars. Took a while to get my head around it through testing it but now getting much better results than traditional Deconvolution, even on noisy data.
In regard to posting images , I do post on various other forums but not Astrobin
I should open an Astrobin account next year

Thanks again
Martin

That’s seriously good Martin and for only 30min quite exceptional!! Theres great depth in the main body of the spider and very well controlled- and yes the rest of the image will probably only reach its full potential with a lot more time. I think we’re all chomping at the bit to get some more time under the stars. Maybe the next couple of nights in Sydney may hold some potential…

Thanks Dave,
Seems like a lot of us are just going over old data and Re processing
Nothing wrong with that as I always find some better outcomes from the original
Yeh I must say this one of the better main cores of the Tarantula that I’ve processed. Startools 1.8 is a winner especially this new SV Decon

A few promising nights coming up in Sydney, fingers crossed

I’ve just assembled a Skywatcher 8” Goto dob for my youngest daughters father in law over at Barden Ridge and now waiting for a clear night to show him how to use it , Star align etc…. He previously had my old 10” GSO push nudge dob which he sold
Things you do for family hey ……

Cheers

It's such an amazing nebula which is not even in our galaxy
30 minutes of data and you can get that much signal.
Wait till you collect 20 hours the results will be outstanding
Scientists say that if this were in our galaxy it would cover half the sky as it is enormous!

Thanks Nik,
It’s definitely a spectacular nebula whether you go deep or wide field
With the weather at the moment I’d have to wait 2 years to get 20hrs
I reckon 4 to 6hrs with the 2600MC , my new Antlia Duoband filter , good seeing and the new 10” CF Newt will expose plenty.
Yeh your right it’s located in the LMC next to our MW Galaxy at only around 160,000 light years away
