A few questions here you've probably heard a thousand times.
Currently I have an 8" Skywatcher and Plossl's 10mm, 17mm, 26mm and 40mm.
After viewing various Messiers and just seeing a galaxy(NGC 3628)

(funny enough this one stood out as a white streak with averted vision but I couldnt see M65 and M66); Im looking at getting a barlow and some more eyepieces.
My question is how much benefit would 2" eyepieces and barlows give me in regards to enhancing viewing deep sky objects and galaxies. Or do they qualify just as good as the 1.25" equivalent only giving a wider view.
What barlows and eyepieces would be recommended both in 2" and 1.25" for viewing DSO's and in turn be also good for viewing the planets. Would purchasing a 2x and 2.5x be a bad choice, and better to get a 2x and 3x.
If you could also recommend filters for better viewing of nebula's and DSO's. Also a moon filter is wanted.
A Telrad or quickfinder is also on my wanted list, though I dont know which would be the best choice, as Ive seen good comments on both.
Last but not least, living in Perth which shop would be the best to purchase these from. I'm about to email a few of the shops shortly and ask about delivery times.
Long weekend coming up, and looking forward to a few nights viewing/hunting DSO's and the planets(fingers crossed weather is good).
Thanks!
