NGC 6888

[peleks]

Widefield image of NGC 6888 HSO pallete, taken with Ha and O3 filters, green color is generated from  30% red and 50% blue.

Exposures 20x15minutes O3 and 10x5minutes +10x10minutes + 10x15minutes Ha (5hrs O3, 5hrs Ha) 

Again season is ended here because in the north we do not have dark sky anymore, most you can do is go for short exposures (30-60sec) with Ha filters for small bright objects like Cat Eye core or Ring nebula, so i am waiting for late July to get some additional O3 signal, because it is not so strong as i want to,+ try to get a good S2. 

Taken wth TS Optics 80mm F4.4 Apo, Atik 490exm, HEQ5 , Baader filters.
