Celestron C6R refractor with HA filter ...

Post by Fabricio-Bona »

Hi all, I´m new here and would like to lissen your comments about put a lunt LS60F or coronado SM II 90mm filter in front of the C6R objective, the focal lenght is 1200mm f/8 and will use lunt B1200 or coronado BF15 together, the adapter is not the issue, just the best choice for this system: coronado 90mm with central obstruction or lunt 60mm unobstructed? thanks a lot.

Hi Fabricio

welcome to that wonderful TOS free site. You will be happy with eighter of the filters. IMHO I would go with the bigger aperture


Only stardust in the wind, some fine and some less fine scopes, filters and adapters as well. Switzerland 47 N, 9 E, in the heart of EUROPE :)

Hello everybody, sorry my delay! First of all thanks a lot for your help, I was observing the sun today with LS60THAPTCB1200 and does not satisfied me anymore, even with lunt zoom or LS60F double-stack, I need to get more detailed and much higher images to share this observations with other people who never seen through h-alpha before, I agree that the 90mm is better even with central obstruction for use with C6R and BF15. Best regards folks!
