Gday
I am a total newbie who has just aquired a Meade ETX105 and am in need of some guidance on EPs. Starting pretty much from scratch as it come with one generic no-name 20mm Wide Angle EP (the previous owner snaffled the standard Meade 4000 26mm plossl).
Scope is 1470mm f14 so I am reckoning max useful mag would be around a 7 or 8mm and I understand optimum performance would be around 2xf14 = 28mm (?). Not looking to go cheapest but not premium either (up to ~$130 an EP). Also considering the Orion Shorty Plus barlow - will this work OK wth the scope/& what EPs? Also, some of the lower cost wide angle EPs get poor reviews in faster scopes but am I correct thinking they will perform OK at f14?
Cheers
