Thanks Paul, I will check out what Dylan is doing. I just realised that the RASA 8 is almost exactly the same focal length as my new TS71SDQ, which already is doing narrowband with existing equipment. So sure the RASA is faster but probably not enough to justify the buy. Time I have. I do have a tendency to get excited about something and then step back when the light of day hits it, so to speak.
So I guess it has just become a general knowledge question then, for other potential RASA 8 buyers.
Must put a note on the fridge: "Do not buy another telescope"!
