Description

This image is the collaborative effort of three astrophotographers (Curtis Collins, Anna Grunseth, and Rolf Weisenfeld) located in the Panama, USA, and Germany respectively.

The telescopes used to capture the sub-exposures were part of the iTelescope.net system. These telescopes are located at the Siding Springs Observatory in Australia. The telescopes used were:
T8 Takahashi FSQ ED (530mm)
T9 Tele Vue NP127fli  (680mm)
T59 Planewave 20" CDK (3411mm)

Telescope T59's much longer focal length was used to capture better detail of the nebula core. Anna completed the final integration work using PixInsight. She selected sub-exposures using PI's SubframeSelector and a good weighting algorithm. Additional sub-exposures were selected by manual review. Given the large amount of data collected she was able to select only the best quality sub-exposures and still retain about 11 hours of total exposure time.

The sub-exposures used in the final integration are listed below:

T08 & T09 Subs:

Ha: 23x 300s, 32x 120s = 55 subs, 2h 59m
OIII: 15x 300s, 32x 120s = 46 subs, 2h 17m
SII: 13x 300s, 36x 120s = 49 subs, 2h 17m

T59 Subs (used for 70% blend into the nebula core in Luminance):
Ha: 14x 300s = 1h 10m
OIII: 13x 300s = 1h 5m
SII: 14x 300s = 1h 10m


The final image was processed in PixInsight and Adobe Lightroom. NGC 2070 Tarantula Nebula Collaboration 20230129
