Very nice image. Amazing what is possible with those filters. Could you give a little bit more detail about the acquisition, equipment and processing?
Thanks in advance

Sure -
This is with an Askar FRA 400, an ASI ZWO 294 MC and an STC Dou filter. The mount is an iOptron CEM40EC.
The image is 20x4min subs captured and processed with AA7 using darks and flats....processing is white balance, DDP, then histogram stretch followed by light application of star compression, sharpen and/or noise reduction as required...and here is a link to a full res version:

and a deeper vsn (10 min subs) with a different colour mappring:
