Old TV 2.5x Barlow or new TV 3x Barlow ?Posted By Roger Sherman |
I have a question---presently I have an old style TV 2.5x barlow and was wondering if it would improve double star images if I would replace it with the more modern 2x or 3x Tv barlows? Or should I go for broke and purchase one of the 2.5x powermates?
For double star work/fun I'm using an 127MM Orion/Synta Apex. ( yes I know-CHEEEP!!But it works! )
If you recommend the newer barlows please tell me why- so that I can learn more about this fascinating hobby.
Thanks in advance, Roger in Tampa
