Description

Almost since I started astrophotography I've searched for a method for "Hubbling" DSLR images. This week I've found a method that seems to work for me.

In this case, reassembling the channels into false "SHO" has allowed me to retain the blue reflection nebulosity that often is lost to narrowband filters.

I wasn't too sure about this at first, but it seems to have created a stir on Instagram, so I've posted it and I hope you enjoy it too.
