eyepieces advise for GSO-8
Hi Guys,
this is my setup -
GS-630
8" f/5 imaging Newtonian on Skywatcher EQ5PRO "Go-To" equatorial mount with tripod
8" f/5, 2" M-CRF OTA reflector has 2" Crayford style 10:1 microfocuser w/1.25" adaptor,
primary mirror cooling fan, 8x50 finderscope and large collimation knobs.
Please advise me Eyepieces and Barlow's or any filters i need to buy.
should i get Eyepieces set? or just 1 or 2 quality ones?
Observation and some sort of photography are the intended use. i have DSLR and T rings and Point and shoot camera which i want to experiment with.
would like to keep budget as low as possible and get just enough to start with.

Do you have any eps yet? Most scopes come with some and they are ' just enough to start with'. After that, make a plan of what you eventually want and buy each ep as you can afford it.

I really have no knowledge of the budget end of the market. If you could give an idea of your budget - total or per ep - I'm sure that would help others more qualified than I to help you. I notice that both Andrews and Bintel (and probably other too) have eps for <$50 each.

150$
for 199$ there is kit available with Bintel but thinking not to collect too many low quality but 2 or 3 only good quality.

Hi Avi, since you have no eyepieces I have a 20mm and 9mm Plossl that you could have for free. They came with a used scope I bought and they're well used but they'll work and give you a bit more time to figure what to buy - send your address by PM or email if you want them.
In terms of buying eyepieces keep your eye out for second hand Explore Scientific 82 degree eyepieces; they're good quality for a relatively modest price. You could also place a wanted ad once you know what focal lengths you want to use. If you're observing from the suburbs you'll probably focus more on medium to high magnification since light pollution will make it hard to see deep sky objects; your highest magnification will be limited by the stability of the air above your location.

Another item that's useful with a newt is a laser collimator: it fits into the focuser, you adjust the secondary collimation screws until the beam hits the centre spot of the main mirror, then adjust the main mirror screws until the beam hits the centre of the collimator target - makes collimation easy.
