Tecnosky 70Q F5 Quadruplet APO

[CCD Imager]

Any one own this scope and can share experiences, especially for CCD Imaging

I saw one at Kelling this weekend and it quite takes my fancy, but with a bad history of short FL  triplet, Petzval refractors in this field, I am apprehensive. I am particularly looking for a FL of 300-350mm. I can't find any reviews or even images taken with this scope.

 

Cheers

Yeah, three years late, lol 

I actually bought the WO Redcat earlier this year, but I would still be interested in seeing how the Tecnosky performs.

Better late than never lols , i will see how second outing goes but first light was good ,build wise seems good other than the dust cap loose fit but i have a friend machining me a better one ,i have added an autofocuser , and will probably relocate guide scope to the guidescope rings , field rotatator built in , and tilt adjusters built in too if needed eos adapter quickly easily fitted ,field looks flat to the edge, too me anyway ,focuser is smooth seems solid no slop ,

There is a review here of a Meade same scope rebranded https://astrobackyard.com/meade-70mm-quadruplet-apo-review/

I'm always wary of Trevors reviews, great chap that he is, he never says anything bad about any astro kit.....

I would be interested in whether focus changes between filters, FWHM of blue images compared with red and green and of course, stars at the periphery of the FOV.

 Im sure I saw another review somewhere might have been skyatnightmagazine I will have a look , I’m not imaging in mono so no filters used so unable to answer that regards fwhm ,  the sub posted as came off camera no cropping.

As you are using a DSLR, then taking photographs of bright stars looking for blue bloat would be helpful.
