My first impression is heavy, it comes in at just over 2 pounds (.9kg). The second impression is nicely made. The third impression is that it goes on the scope with out fuss. Take off the flattener and screw on the reducer-flattener.

 

The next impression, the one that counts the most is it works and works well with an ASI2600Pro, Sensor: Sony IMX571 Diagonal: 28.3mm, Image area: 23.5*17.5mm. 

 

The image circle is 34mm for the 120mm Esprit. The camera side is M48 x .75 and the back focus is 55mm, just right for the included spacers in the box with the 2600. You have the option to fit a custom adapter. Adapters are available for the Esprit 150mm and the Evostar 150 ED.

 

Did I say it weighs in at 2 pounds?

 

The only direct comparisons I can make are to a TV-85 with a TV .8x reducer - flattener and the Starizona Apex on an Esprit 120 ED. The Apex had obvious vignetting due I am told, to Starizona' s failure to test the Apex on a 120 or to provide early customers with what is now a required and extra cost extension tube. The best that I can do is to say that it is as good or better than the TV setup and that I do not see any shortcomings.

 

 It works nicely with the L-Enhance which is about all I've had a chance to try.

 

Bottom line-- I like it and I am going to keep it.smile.gif
