M51 (Ramsay McIver) Takahashi FSQ-106ED with a Tak x 1.6 adaptor and a Canon x 1.4 on a Celestron AVX unguided with a Canon Ra. 31 x 30s @ ISO 6400 and 25 x 15s @ ISO 25600 stacked in APP and processed in Photoshop. No flats or darks were used to make this image. I think using the Tak 1.6 and the Canon 1.4 is just about taking the magnification as far as I can go, similar to a 1187mm lens on a FF camera.

Continuing to learn the use of NINA for acquisition. Guiding last night was superb, around 0.5 arc seconds. Stack of 41 x 180 secs at 121 gain and 20 offset. Sensor at -15 C
