Description

Data taken 3 years apart from SE London in March 2016 and Early 2019
Disappointed that my 2019 data did not reveal much Oiii so I combined the data from both years into one image.

Taken with completely different equipment slightly different orientation and different scale.

2016 ED80 and Atik314L (3 hours Ha, 45m Oiii and 1hour Sii)
2019 SW130PDS and Atik460EX (3 hours 20mins Ha, 1 hour Oiii, 1 hour Sii)

Totals
6 hours 20mins Ha
1h 45mins Oiii
2 hours Sii

Grand total 10 hours 5 mins
