Before I start with the dumb questions, a big thanks must go to everyone who helped me to choose a scope (SW 10"dob) and associated bits and pieces, great advice and I'm having a ball discovering the heavens. Particular thanks to Eric, Rob, Steve and Brendan. I've been out every night since it arrived and every night I find something new and amazing.
Tonight is cloudy and with the happy coincidence of being sober, it's time to ask a handful of questions that have popped up over the last week.
1. Barlow lenses. 2x seems to be the most recommended, but are 3x worth considering. Being a bloke, I'm biologically programmed to thing bigger is better, but I'm assuming that there is a trade off somewhere.
2. Are 2" eyepieces worth the extra expense?
3. While I was looking at the Orion neb, I noticed it was green-blue (much different to all of the photos that I have seen). I thought that I had read somewhere that most visual observation would be b&w, but obviously not. Would filters help give the actual colouration of DSO's? Reds are visible in stars, so why not in DSOs?
One final point, whoever invented the Telrad should be awarded the highest honour afforded by amateur astronomers - it's brilliant:D
Cheers,
Craig
