My extravagance knows no bounds, well almost as this filter was pre-loved?

Here's mine, goes anywhere. About 8 kilos I think but for aircraft travel the mount and tripod go in checked baggage the rest with me. 

 

 

 

Nice looking mount! Can you provide details please?

Hey I thought I already mentioned that I split the double double near Vega. I take it this is what we are talking about?

Close but no cigar!

The double-double is actually Epsilon, so you are close in a way:) 

I've checked my astro log and the smallest aperture that I've recorded an observation with is 250mm (f4.8 Newt), so I'm not sure what the practical minimum is but give it a try! Theoretically 60mm should be enough with good seeing. Good luck!

Regarding my images using the Tak FS60CB, I should add that these images were taken using a crop Canon 40D (astro modified). Pixel scales as measured at http://nova.astrometry.net are as follows:

252mm, 4.59 arcsec/pixel

366mm, 3.14 arcsec/pixel

610mm, 1.86 arcsec/pixel

HTH, Andy

shout out for the versatility of the light-weight Tak FS60CB system - some images for your consideration at 252mm (reducer @ f4.2), 366mm (flattener @ f6.1) and 610mm (1.7x extender with flattener ~f10). Admittedly used on an AstroTrac rather than the SA...any excuse to post some of my photos 

HTH, Andy

Antares & Rho Oph @ F4.2

NA and Pelican @ F6.1

M20 @ F10

Sun & Moon @ F10

My current solar eclipse gear (and me) in action on Monday near Moose in Wyoming - well it was night-time for just over 2 minutes lol

My travel setup for local dark sites and beyond. Tak FS60CB usually with F4.2 reducer (fl=252mm) but shown with 1.7 extender & flattener (fl=610mm) for the solar eclipse. Just added guiding kit for some nighttime imaging at this focal length on my AstroTrac. Camera is a modded 40D.

I love my FSQ85/QSI690 combo! - at native focal length though
