NGC2070 Tarantula Nebula (in between the clouds)

Post by Startrek »

At my City suburban location I have a restricted view of the SE to SW due to my 2 storey roof line and huge council tree , therefore I can only capture a few hours or so on this target each night.
The weather over the past month has been cloudy but last week offered 2 relatively clear nights ( some passing cloud around 11.30pm to midnight)
I was lucky enough to capture around 4 hours on the Tarantula over 2 nights although I discarded about 15 subs due to cloud and a huge tree in which one smaller branch just blocks its path.

New Moon period
Bortle 8 heavy light polluted skies
Sky conditions were generally clear with late passing cloud
Atmospheric conditions quite stable
8” f5 Klaus Helmerich Carbon fibre Newtonian ( built it myself )
Skywatcher EQ6-R pro mount
ZWO2600MM. Cooled to -10C , Offset 50 , Gain 100 ( HCG )
ZWO 7x2 Filter wheel
TS GPU coma corrector
Antlia 2” SHO 3nm filters
Goto and Nav EQMOD and Stellarium
Acquisition APT
PHD2 Multistar Guiding ( 0.45 to 0.55 arc sec )
Ha 52 x 2 min subs
Oiii 35 x 2 min subs
Sii 37 x 2 min subs
Dithered every sub
Full Calibration Suite
40 x Flats for each filter
40 x Flat Darks for each filter
40 x Darks from my Library
Analysed , reviewed , calibrated, stacked and aligned in ASTAP
Post processed in Startools V1.8 using Compose module and mapped SHO

The 2 min subs through my 3nm filters worked really well for such a short integration of only 4 hours

Very happy with the end result in SHO

That really looks great, Martin! :) So much detail at only 4 hours of integration time. Mono and high quality filters really seem to be the way to go in case of such light polluted skies.

Nothing to improve as far as I can see. Unless you want to consider to cut the branch of the council tree ... ;-)

Thanks Dietmar,
Yes very pleased with this result
Unfortunately the trees branch is up around 25 meters high so not going to climb that high , plus it’s a fine $$$ as it’s a government tree.
I’m just happy to image it as it’s a great region in the LMC

Clear Skies
Martin
