Description

Taken over two nights with plenty of cloud leading to quite an imbalance in the numbers of subs from the three narrowband filters, around 4 and half hours each of Ha and OIII and only a little under 3 hours of SII.

Stacked and pre-processed in APP and separately in Startools (both as SHO).

The highlights were better proteted in the Startools process so in PS I combined the best of both in the result here..

This is a new target for me and only my second serious attempt at mono. I am enjoying the greater range of colours I get to play with in mono and am happy with my new narrowband filters than seem less prone to halos compared to the Lextreme (which is stillan excellent filter for OSC).
