First image using my new Canon 70-200 f4L IS lens with the 2600MM-Pro & Chroma filters.
I'm hoping this lens/camera setup will serve as a decent travel rig in the future.
Few challenges reaching the 44mm back focus needed with a Canon lens - a 10mm TS EOS adapter and 1.5mm spacer provided the necessary correct distance.

Another first for me using Flat calibration frames due to the central circular vignetting that the lens produced and bit of a halo around Antares even with Chroma filters are initial 'cons', but otherwise happy with first light.
Thanks for looking
