Subject: Re: Barlows and Mars


Hi there fellow Martians




In any case, I just bought a 3x TV barlow for a better focal ratio

than I was capable of 

before. The 2x I was using was a mediocre Celestron with some

apparent dust specs that 

I've never been able to clean. I was amazed I was able to get any

kind of image with the 5x 

and compared to the original, I'm even more amazed.

I used my 90mm WO with 3x Tele Vue barlow yesterday night to take my

first Mars image this season. The result is not that great due to the

unstable atmosphere and short focal length of the instrument.


But I fully agree with your views, it is worth to invest in a good

quality barlow!
