I am using the plain old Skywatcher/Merlin head with Papywizard and Bluetooth. I had wondered if the TC Controller was faster somehow, but I don't know why it should be able to do something Papywizard can't (The tread you reference doesn't explain why it is so much faster at small angles, as in the video
Are you saying that things run faster with "mirror up" selected in Papywizard? Or, are you saying that you can reduce the stabilization time if you use mirror lock-up? I am using a mirrorless micro-4/3 Olympus E-P2, so I never bothered with the flag.
I have been wondering where I can cut some time out, but the only places I see time are in Stabilization and the Low and HIgh Pulse-Width. All of those put together are far shorter than the times I see. In fact, my shutter is firing very soon after it stops, but it seems the head sits there a long time after that before it starts to move again. I think it is nearly 10s between shutter firings when it is only moving a few degrees. There is seemingly more time sitting still than moving.
How low is it safe to cut the pulse width? My stabilization is at 0.3 s right now and I believe the pulses are both at 0.2s (whatever is default).
The TC definitely speeds the Merlin up - in combination with the accu-set Josef provides. Both result in a speedier Merlin. But the video seems to me a bit illusionary . .
With lenses of more than 105mm the Merlin slows down dramatically. ThatÂ´s because thereÂ´s a combination of "move to" and "go to" - with short lenses first it moves fast and then slows down to "go to" the final and exact position. With lenses of more than 105mm the head uses the "go to" speed all the time - and thatÂ´s very slow because of itÂ´s precision.
Stabilization time after mirror-lock is vital - without a short wait-time before firing the shutter the mirror-lock would make no sense at all.
Mirror-lock would be useless without a wait-time to let the shaking come to rest. So there is about half a second of wait-time after the mirror has locked up and before the exposure starts.
