After a few days focused on white light and CaK images I reloaded the HA (PST mod) setup on the Omni 120 XLT.

I recorded all the main ARs and a huge prominence SW. I also made a dedicated recording but I’m processing it right now so I’ll post it later.

The 3 images are good in my opinion. Also thanks to the good seeing. Much better than the previous days.

Here they are:

I used the Celestron Omni 120 XLT + PST Mod (Etalon + BF5) + D-ERF 75mm (inside the tube so to have a 100mm aperture) + DMK41 with a x2.25 Baader barlow and Baader Neodymium filter. The focal length has been around 2250mm.
