Hi all

I've got an 8" Bintel dob, with just the 3 standard eyepieces + an Televue 3x barlow.

Someone recently strongly recommended getting filters - I am particularly interested in being able to enhance the view of nebulae, (he mentioned hydrogen beta) but in the couple of days of researching I see Oxygen 3 filters mentioned.

I would appreciate any suggestions .

Thanks
Mark
