Spent a couple of hours observing with the 160mm Tak and comparing it to my 200mm string truss dob. Jupiter is over the roof of the house now and thermals off the house are affecting the seeing in that part of the sky, so I have given up for the night.
Seeing was much better tonight, 5/10 most of the time, with 7-8/10 on occasions.
Both scopes showed a lot of detail on Jupiter during moments of good seeing @ 222X to 285X. I felt the 200mm showed slightly more detail, but there wasn't a lot in it. Interestingly the Tak, during moments of good seeing, showed beautiful complete diffraction rings around Jupiter’s moons. The 200mm did show the diffraction rings but they tended to be broken and less steady.
Antares was a surprise. The Tak showed a wonderful clean wide split @222X. Once the 200mm mirror had cooled down, it too easily split Antares, however, I must say it did look a little cleaner in the Tak
.
Now I have to decide on how to finish the scope
