Meat hook test image from RC12 Remote

I am still finalising the commissioning of the RC12 in the remote dome. Last night I took some data of the Meat Hook galaxy (NGC2442). Collimation is a little out but only about 3.5 arc seconds, guiding was ok. I did not do enough focusing with focusmax, once an hour and that resulted in some subs being soft.

This image is Luminance 70 minutes with 10 minute subs. Stars are round at both 5 minutes and 10 minutes. I am thinking that I will need to go to 15 minutes or 20 minutes to undertake imaging with this object.

Despite the focus softness the detail is still present and for only 7 subs the noise is reasonable.

Both images are crops. I have not done flats, darks or biases. Though I will be starting to collect those very soon. Flats will be done at dusk and dawn in future.
