Description

Here is a very cool collaboration between @FranckIM06  and me.We combined our datas on Abell21.Franck imaged it with a narrowband filter and me with a broadband filter.
With the narrowband filter the nebula shows it wonderful extension and the broadband filter helps to have beautiful stars.The quality of Franck’s datas was a pleasure to process.
