Hi All,
I just got a JMB filter for about $110. Fits over my Orion ED 80 mm. It's not bad - but the image is much crisper (although dimmer) with a 7 nm H-alpha in as well. Well, I think it is, as since I've had it (1 week?) its either been cloudy and/or there has been absolutely no details (sunspots etc) to be seen at all.
This morning I was thinking about a good place to have a look near where I live (Fremantle, WA). There are a number of hills with parks on top - one particularly good one is Wireless Hill Park which also has three 10 m high solid concrete towers. These are left-overs from a WWI and WWII radar and telecommunications station.
Problem is that in WA, I'll need to up at about 4:30 am
and at the park at 5:30 am and the gate doesn't open until about 8 am or so, so I'll have to park outside and carry all my gear - telescope, camera, tripod, mount, battery etc etc.
