I own a new bintel DOB BT 202: Aperture 203mm, f/5.9, 1200mm Focal length.
Bintel 30mm wide view, Plossl 20mm, Plossl 15mm, Plossl 9mm.
What would you recommend be my next purchase?
Should i go down the Barlow path? I realise this may open the gates to many suggestions but was hoping there may be an obvious next step.
