This astrograph has the built-in filter box, which allows to set and swap various filters without disassembling the system. If you use par-focal filters, you don’t have to re-focus each time. This function should be very useful for one-shot color cameras when Ha frames and regular RGB frames are taken separately. Thanks for sending the image, Charles. Keep enjoying astrophotography with BORG!
