Thanks for seeing me! Just joined the lounge and looking for some advice.
I am a few-weeks-old newbie, recently bought a Skywatcher Heritage 130P f/5 Dob (bought for my 8 year old but having too much fun with it myself!) and looking to upgrade the eyepieces that came with it (the generic Super 10mm and Super 25mm). I also bought a Celestron 2x Barlow and Celestron Omni 4mm Plossl within a few days of buying the scope.
I live in Sydney, Australia, in an area with quite bad light pollution and little visible sky (about 45 deg in the East/South East) - trees and houses block most of the sky from my balcony. However, I've been fortunate enough to have Jupiter, Saturn and Mars, and the moon visible from my balcony late at night/early morning for the last few weeks and have made the most of it! So much so, that I'm wanting to improve things as best I can with eyepieces, while also planning for the future when I have a bigger scope and better view (and even just taking my 130P out into the middle of nowhere on occasion).
I wear glasses and have astigmatism but tend to take my glasses off whenever I look through an eyepiece. Short eye relief doesn't seem to bother me, yet. Using the 10mm with my Barlow, or just the 4mm (or even just the 10mm) I can see the bands and GRS on Jupiter, I can almost make out the Cassini division on Saturn and the moon is obviously full of detail (Mars has no surface features visible - desperately waiting for the opposition in July!). I've probably been blessed with good seeing over a few nights of the last few weeks.
Anyway, I have about $500 AUD (Australian Dollars) that I could potentially spend on upgrading my eyepieces and wanted some advice (I know I could put this money towards a better scope, but I just want to get the most from my 130P right now, while keeping an eye on the future). From the limited research I've been able to do, I had come to the conclusion I should buy a high-end eyepiece for planetary viewing (maybe a 7mm Televue DeLite), a blue 80A filter and maybe even replace my current Celestron 2x Barlow with a TV 2x Barlow or maybe even one of their Powermates (or their 3x Barlow).
I can't seem to find many second-hand resources here in Oz, so am looking to buy new, unless something better is presented to me.
Given all the info above (happy to provide further details if required), what would you recommend?
