It will depend a lot on what you do with it
I use star masks for a bunch of things but probably most commonly for reducing star size and boosting star colour.

I don't want to take anything away from the image posted here, but talk of 30 min narrowband subs is rapidly becoming 'old school' with the new camera developments.

I think it's a little too early to read an obituary for "old school" imaging yet. It still seems to work
The new CMOS technology is promising but it has a way to go before it's a solution to every astro imaging need. The ASI1600 sensor does not suit long focal lengths and it's only a tiny chip, 1/4 the size of the one that Scott is using and 1/6 the size of mine.
I'll be happy to switch cameras when I can get something better than a KAF-16803 sensor for the sort of imaging I want to do, but I don't think it will happen for a while yet. In the meantime I'm very pleased that there's a low cost alternative to DSLRs at the entry level.
Cheers,
Rick.
