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.

So back to an old favourite last night, M51, using my 6″ Classical Cassegrain ( which is not really meant for DSO’s, but in the absence of planets…. ). 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
