Sky Watcher All View Mount TO Buy or NOT to buy-llema
I have decided to buy the multi purpose ALL VIEW AZ. ALT Mount $800 (in India!) because..
1. I do a lot of video shooting and the motor controlled mount is Worth half the money for me.
2. I do 360x180 panoramas (Self made Panoramic-Head)
3. wide AP.
Query
A.
I have 2 heavy Manfrotto tripod legs (3/8" thread) so can i use my camera tripod legs n carry just the Allview head/Mount only.
B.
I was thinking of putting the AllView head on the photo tripod head and use the tilt (down) to line up the Base (Axis) to NCP.
C.How difficult will it b to
Polar Align an Azalt mount on a wedge in the field ?

Barn Door for astrophotography
The Barn Door Works!
After initial bad luck n effort, last night I managed to get over 20-30seconds! With a 90-300mm (@1.6x thats about 480mm)
With $1 !
It's such a elegant idea.
Simple.
1.Take 2 plywood boards of12x18inch.
Join the 2 boards with a hinge( see image).
2. Make a hole EXACTLY 11.4INCH AWAY FROM THE HINGE-PIVOT.
3. Fix a 1/4-(tripod plate screw size) NUT thru the hole. Seal it with super glue.
4. Pass a 3" long 1/4 bolt through the nut.
4.5 Acc to mathematics the 1/4 screw will move 1° in 4 complete turns. Earth rotates 1° in about 4mins!!
So u have to turn the bolt at 1 rotation per Minute. Which is thr speed of the seconds hand in a clock.
5. To make the turning smooth use a metal piece like a Ruppee coin at the point where the Bolt pushes the board.
6. To make the rotating each n precise, stick a long plastic handle.
Make a clock face for you reference.
7 To make it Even more smooth PULL the plastic handle with a RUBBER BAND. This will be needed for Telephoto lens.
Picture s come here.
