Captured the Monkey Head Nebula with 60 × 5 minute subs for a total of 5 hours of integration using the Optolong L Ultimate. Shot on my usual rig with a Celestron NexStar 8SE at f 6.3 with the focal reducer, ASI533MC Pro cooled camera, guided on the EQ6 R Pro and captured in NINA. Solid narrowband performance from Bortle 8 9 skies with the L Ultimate doing the heavy lifting to pull out strong Ha and OIII signal.
