Thanks Al and Chris, your comments regarding focus are much appreciated. I made a Hartmann mask and gave it away and returned to visual focus. The two speed remote focus works perfectly, but atmospherics and age still makes it difficult to get that exact point. It's a guess most times but occasionally one gets it spot on. Thanks Bassnut for your comments, but I'm confused with the suggestion over stretched. Is this term associated with FPS? I must admit I mostly use 60 fps. How does one decide when to use 30 or 60 fps?
I'm still concerned with the focus of the Barlow onto the DMK CC chip. I fail to understand how the Toucam I had and the DMK I'm now using, can both be in focus when both are a different length from the face of the chip to the Barlow lens.
When I recorded Jupiter and the two moons, something I've only achieved with the planet being over exposed, it came as a surprise. The following evening I tried again but no moons just a shadow on the planet.

I'm using a 250 mm GSO on a Eq platform DMK 21 and 2 x Barlow. Registax and Photoshop 5. One dissapointment is the difference between the laptop display and the desk commputer that sends these pictures. What looks great on the laptop is dark on the desk computer.
