Description

The RGB is from Aug 2016 the NB was taken on the 9th April 2017. The NB stacks were created then registered to the Red channel of the 2016 data.

The NB set was my 1st image of the year in fact the 1st since last November the weather was that poor. The thing I had forgotten was to focus again, hence the NB is bit out. So hence another sows ear purse thingy image.

Rev A: The extracted Lum from the NB HOO.

Rev B: The RGB with Ha added to the R and OIII added to both G and B channels.

Rev C: The NB combined as a HOO with RGB stars added.
