About vibrations, the C8 with under the pads inherited from my ex Nexstar SE, at 250x when touching and turning the focus, the vibrations disappeared almost instantly. If instead hit the tube, vibrate out in 2s, timed.
The test with the reduced C8 and a Canon 6D:
We have, on 6 frames total of 30s each, 4 good with 1px trailed, 6 good with 2px trailed. To be seen in the concrete how the software correction of the trailing of 2px deteriorates the sky background. The 1px trailing correction itself doent impact the general image.
Images examined at about 240x.
We speak now for a second about ergonomics: The declination and height indexes are really gross. As well as there is a mini mini space between the two rotating parts of the RA axis not very nice to be seen. The dovetail clamp in DEC makes me definitely laughing ..... The tripod is very tall, more than the AVX and, as I say, has a "wingspan" of the legs not really compact.
The test with 300mm f4 on Canon 6d. On M67 cluster.
On a pack of 6 photos of 3m each, we have 4 photos well done, the other 2 trailed. Stacking with DSS the good ones pose no problems, . By stacking all pics with DSS we have a trailing of 1px, which, as with the C8, can be corrected in post.
