What eyepieces did you get with the scope? I just realised, the Heritage is a Dob isn't it?! I think a decent wide field EP would be useful. Probably need to go no greater fl than a 32mm as I'm not sure if you would get secondary mirror issues with anything lower mag - perhaps someone else could comment! As for higher mag, I think a 10mm or 12.5mm would be as far as I would go. FLO have some Astro Essentials Plossls which have good reviews and are reasonably priced - not sure how they would perform to be honest, maybe give FLO a ring and ask ( I don't work for them!). Also, keep an eye on the classifieds if you want to keep the costs down and don't be afraid of trying things out. Hopefully some other Dob owners can comment on what they use most often. Good luck with your new hobby!!
