Field report by Jörg Weiskopf:In order to escape the bad weather and to be able to photograph under really good conditions, I had looked for a lighter travel equipment.
I found the new Star Adventurer interesting, because I didn´t want to work only with wide angle or light telephoto lenses. But also with a smaller APO I chose an EQ3 from Skywatcher in the SynScan version, i.e. with GoTo.
The advantage of this variant is the true two-axis control which is autoguider and GoTo capable.
This saves a laptop when travelling, and after the 3 star alignment, the automated approach of the celestial objects is amazingly accurate. The focus finding is done comfortably via smartphone using the qDSLR dashboard. During the alignment I placed the stars in the center of the DSLR image at 10x magnification of the Liveview image. More was not necessary.
The alignment to the celestial pole was done first. This went with the pole search telescope briskly from the hand. Since the GoTo allows fast panning movements, the mount was no longer moved or touched by hand. So the lighter mechanical version of the EQ3 (airworthiness was important) still fixes everything with the necessary accuracy.
Finally, I had the handheld control unit modified with a Bluetooth transmitter unit, which makes it even more comfortable. With SkySafari Plus a very nice addition and remote control of the GoTo is now available via tablet or smartphone.
As optical components I had chosen the recommended TS ImagingStar 71 with a 50mm mini guide scope. The APO is characterized by a good image quality up to the edge corners and also good color reproduction. In addition, it weighs 2.4 kg complete with dovetail bars and is very well supported by the EQ3. Focal length and focal ratio also provide good conditions for successful shots. Single exposures up to 8 minutes have been done without problems - longer exposures were not necessary with F=4.9.
Handling with the mini guide scope and focus scale is comfortable, guiding with the Lacerta MGEN is easy. Both in terms of finding the guide stars and the quality of the tracking achieved. All in all, I think I have made a good choice.
Also used good optics - experience report of a second astrophotographer

Experience report by Gabriel Siegl:Hello dear TS-Team
I recently bought your TSQ-71ED from a friend and I am honestly really excited about this instrument. At first I didn´t think that with such a short focal length you can really notice such a good edge correction, but after the first exposure session I was proven wrong - beautiful point-like stars in the very corners of my EOS 6D.
Taken with the TS71 and the Canon EOS 6D (mod)
Yours sincerely
