Hi Doug

yes I did , no vigneting issues, but the focallength of the barlow is 105 mm and attaching it to the Leica , means it works with much lesser backfocuse, so I see quality reduction of course, so I do not advise to use it such way

Markus,

I am envisioning using a barlow like this with my Mewlon 250 and Flea3 webcam for planetary imaging. Your 1.8x I have works with a lot of extension tubes (but is perfect for my C14). This should eliminate that need. Does that sound right? Also, as I mentioned when we talked in Tucson I'm really hot to get your new 152mm ED doublet next year for dedicated solar. This barlow should give me sufficient amplification for killer sunspot images! Does that sound reasonable to you?

Thanks!!
Paul
