Crikey, bikey! That is exceptional. I only wish I could get that. Using an LX200 on a wedge, I'm flat out locating SCP, let alone pulling guiding results like that.

As for not being smart, I would think you sell yourself somewhat short, sir. I have read numerous, very informed and articulate posts from your good self, on a wide variety of topics on this forum.

Hi Shane
Thank you for your kindness and compliment.

Maybe a little smart but lazy maybe.

When computer programs etc don't work I don't know what to do.

I feel helpless because I am not great with computers...

I presume if you have a wedge you have a fork mount???

I find the CSP by placing the scope in home position and then take a time exposure so I can see star trails..the scope is not tracking but sits stationary during this proceedure...

Look at the capture and then adjust the mount until you have concentric circles ( arc of stars really) and you can have the center of these circles in the center of your capture.

I think you could do similar with a fork mount by setting your scope parallel to the forks ..take a time exposure that shows arc star trails and the adjust the wedge until you get the circle centred.

My mount is an eq 6.
But I pulled it down and made sure every thing was polished each gear tooth and removed the greeese and used a very light machine oil...I am unbelievably a perfectionist so trying to make the mount perfect somehow appealed..I did a few things that were probably extreme, can't remember,...
One thing I would have used was a tube extending past the camera lens by seven inches with baffles to restrict star light from anything outside the field of view being able to strike the lens.
I had these tubes for all my scopes ...and that was probably obsessive but I think it improves contrast.. I never tried with and without which I should have determine if the effect that I believed I achieved was real or imagined...
But after I "invented" these tubes I noticed that Hubble has a similar extention.

I posted this.elsewhere on this forum.but post it for.you here... It's like a long few tube with baffles.

It should be flocked as well really.

Notice how the tube goes well past the secondary and that extended section is baffled.

Sorry your scope should be parallel to the wedge ..I think that's right but I am trying to imagine something I have never seen in the flesh.

That shot was with my old crappy mount..called an eq5 but it was well before the white eq5s.

I did work on this mount but is was terrible.

This is how I remembered... Over ten years ago.
