I'm not going to pass comment on Tom's equipment as I know next to nothing about telescopes. But now you know what Tom used to confirm Rowbotham's experiments and its specifications.
I'm sorry Roundy but Tom did not confirm Rowbotham's experiments.
First he did not make his observations on a six mile straight canal where there is very little or no movement of the water.
On a very clear and chilly day it is possible to see Lighthouse Beach from Lovers Point and vice versa. . . . on the adjacent beach 33 miles away.
Second he did not observe a boat sailing away from him on this body of water, (Luckily, Rowbothm fails to give a description of the boat or we'd spend 20 pages discussing that) as Rowbotham claims to have done.
I didn't do my observations with ships. I did it with distant costlines. You can find a description of my trials by doing a forum search for "Monterey".
Third, Tom Bishop does not mount his telescope (which does not appear to be 'high-end) 8 inches above the surface of the water.
. . . laying down on the stomach at the edge of the shore on the Lovers Point beach 20 inches above the sea level . . .
Fourth, Tom Bishop does not claim to restore objects that have disappeared because he claims (in another thread) that with his telescope he can see children playing on the target beach but does not say if these children are visible without the aid of his telescope, only that the beaches are visible. however he does not say if the beaches are visible with the naked eye from a height of 20 inches above the surface of the sea.
On a very clear and chilly day it is possible to see Lighthouse Beach from Lovers Point and vice versa. With a good telescope, laying down on the stomach at the edge of the shore on the Lovers Point beach 20 inches above the sea level it is possible to see people at the waters edge on the adjacent beach 33 miles away. I can see children running in and out of the water, splashing and playing. I can see people sun bathing at the shore and teenagers merrily throwing Frisbees to one another. I can see runners jogging along the water's edge with their dogs. From my vantage point the entire beach is visible. Even with the unaided naked eye one can see the beaches along the opposite coast.
I'm sure that there are more observations that could be made about whether Tom Bishop has faithfully re-created Rowbotham's 'experiment' but I'm not going to bother looking for them. It is sufficient to say that Tom Bishop looks through a telescope and claims to be repeating Rowbotham's observations.
He is not.
