1st Narrowband

A very quick and dirty Ha from last night - my 1st.

10 minute subs appear to be fine - perhaps try 20 tomorrow if clear.

Comment welcome but guiding looks okay and the is more Ha in this target than I thought.

As a supplemental question....

I presume longer subs would reduce the noise which appears to be as a result of stretching the image?

Yup. You will still get some noise from long exposures but MUCH less than a really stretched image.

20 minute subs it is then.
