I love my Swift Audubon 804 HR5 for daytime, birding etc. so I decided to get some waterproof Audubon 828's for astronomy and WOW! They are 8.5X44 like the HR5's but being roof prisms (Phase coated and fully multicoated) a smaller FOV (6.5 v/s over 8 degrees) but star colors are well saturated and pinpoint!

Hello Mike,

 

Is there spiking on bright stars or planets?

 

Stay safe, 

Arthur

Hello Mike,

 

No spiking with a roof prism is a sign of a superior binocular.

 

Use it well.

 

Stay safe,

Arthur

Pretty cool. An 8.5x44 roof sounds about ideal for handheld portability and quick looks.

Hi Mike

I bought an old Audubon mk2 a while ago, The view is fab but no sooner had I got them home than the focus started sticking!, A few days later I tried them again and they were perfect again!! shocked.gif
