Up to EC-RGA less than a month. This is not a 36x increase. Well, not more than 15. Soviet 20 times the pipe significantly increases. Eyepiece is smaller than 10mm diameter. Brightness is less because of this.
The product is very good, it performs its function. Thank you!
You can pamper, and so the increase is so-so ..
I liked it very much, I recommend the seller, I received the product very quickly
