Description

NGC6888 image taken with an 8 inch Newtonian at F 5.0 and f = 1000 mm under Bortle 6/7 skies .   

A NB OOH image was  combined from 5.5h of O3  (6 nm filter) and about 2h exposure of HA (7 nm filter) taken using an ASI 294MM PRO mono camera.   This was combined - in proportion to SNR - with an~ 3h OSC UHC-filtered OSC image.   BlurXt was used to deconvolute the starless NB images and StarEXterminator to extract and then re-add RGB stars

All captures were using Sharpcap and preprocessing / processing in PixInsight
