Description

Tarantula area (30 Doradus) (Caldwell 103) (NGC 20770) in HRGB.

There is so much happening in this field.The tarantula is said to be one of the largest HII areas and the largest startburst area in the local group of galaxies (2000-3000 LY across depending on source!).It is on the leading edge of the LMC as it moves through space so is being compressed and eroded by the interstellar medium.

And its really bright (naked eye visible in the presence of a half full moon say better observers than me eg S. J. O'Meara), though extragalactic (160,000 LY away). In fact O'Meara says if it was as close as the Orion Nebula it would occupy 60 degrees of sky and outshine Venus (pp408 in "The Caldwell Objects" - reference included because that comparison seems to get bigger and brighter every time I see it written somewhere!). 

So I can see blue (young, massive) stars everywhere (many class O3 = 100 solar masses), dark areas where the light pressure from the young stars has eroded their natal dust cloud (and especially a cute spherical one in the extreme bottom right where it looks like a single star is emerging). There appears to be plenty of dust or molecular cloud to make more stars from yet. There are dust streams (see bottom left corner), Ha excitation (red, ok I boosted the saturation a bit, but where there's red smoke there's Ha), blue dust nebulosity especially around the tarantula itself, and some at least token stars in the area of NGC2070 where a cluster of bright new stars is said to illuminate the whole Tarantula structure. And I wish I could say I could see  1987A and the supernova remnant around NGC 2060 (N157B) but I cant even locate NGC2060 although its said to be close to NGC 2070 so the platesolving in Astrobin might show me where to look. And I have to admit the one big thing I can't see is the Tarantula structure of limbs and cavities itself, but that's the price for using Ha as my Luminance layer. (HRGB) 

This was a return to astrophotography after months and months of rain and cloud so a big bright easy target was called for. 

The James Webb has recently shot the area as well -- https://www.nasa.gov/feature/goddard/2022/a-cosmic-tarantula-caught-by-nasa-s-webb

Exposure: Quattro 200mm, Zwo 194MC for RGB (31x180s,120x,-5deg,Bin 1) and 194MM for Ha (47x300s,120x,-5deg, Bin2). (The 5sec series for rgb stars got wiped out by moonlight and cloud), Coma Corrector, EQ6, Oag guiding, processed in Pixinsight.

15/11/2022. Suburban backyard bortle  5, seeing 2-3/5 transparancy 2-3/5 - a pretty good night for my location.
