I love how the star spins around like a barber pole as you blow air through the drive tube.

Congrat Khang. Does anybody here know how and has actually used this lens before? Just curious. Thanks

I think it takes two exposure. The rotating star is a mechanical center filter. Take one exposure without star and one with the rotating star (to compensate the light fall off at the corner)

150mm definitely covers 1220.

If you bought this lens, probably you have already know how to use it. This baby is really expensive...

BTW has anyone seen a 200mm hypergon?

I remember reading that you should do 2/3 exposure with the star spinning and 1/3 without the star in position.

now you will need a 'Sky-scraper' camera to go with the lens.

Have fun with it

The 20 inches Hermagis does not cover the 20x24 but these are and I can't wait to put them on the 20x24 to satisfied my ego. Here they are !The smallest are the Darlot Petzval for 5x7 for your compare the size.

Jack,
As you know it took a quite some time to built up your collection knowing what you want . The fun part is hunting them gather all the siblings and see the result from them . At this time I would say no they are not for sale but in the future who knows right? Cheers.

If you plan to shoot 1220, that's the way to go. I bet hass will be more than happy to build one for you. :D
