NGC6888 in Ha from last night


glider

Recommended Posts

2 hours worth of 5min subs, no bias, no flats yet.


 


Atik 314L/Astronomik 12nm Ha/TS ED80 on HEQ5 Synscan Pro. Guided using QHY5/ST80/PHD.


 


Stacked in DSS, deconvolved in CCDSharp, levels and curves in CS3 and final noise reduction in Neat Image.


 


Now all I need is some more clear nights for the OIII and SII.

Enjoyed and then some.


That is one brilliant picture :notworthy:


I have got to get me one of those HA filters.

I managed to collect 3 hours of SII last night so no more synthetic green generated from the Ha and OIII.


 


This is mapped Red-Ha/Green-SII/Blue-OIII

This is Hubble as Red-SII/Green-Ha/Blue-OIII
