This lens is excellent in my honest opinion.
Round stars in all 4 corners even with full frame sensor and no weird shapes either.
It even comes with kit (belt and pulley) to install your EAF. Easy set up, light weight and it looks pretty cool in black and red.
Highly recommend.
I would also recommend Dark Clear Skies as they have dispatched my lense on the very first working day, and it got delivered the very next day. Just in time for some clear skies and first light.
Over all excellent experience with lense and family run business too. Huge thank You.

Paul has been absolutely astounding in his support with regard to purchasing this camera, and I could not have asked for more! Highly recommended. Thank you...
I am so pleased with this scope as the stars right into the corners of the frame are so sharp and clear. I compared this with a Redcat 51 and the Svbony is far better. I sed the scope with a ZWO 2600MC Pro. The image attached has been reduced in resolution but you can see the full image on my Astrobin page https://www.astrobin.com/el0b7l/ . Paul at Dark Clear Skies was very helpful in enabling me to return a defective scope from the "First" which were know to have a few problems. The one I have now is just about perfect

A few of us viewed the partial eclipse today with our solar viewing glasses and nobody has reported any sight problems, so they seem to do their job effectively. Ordering was straightforward and delivery was quick, so absolutely no complaints from me!
