After hearing many good things about the SV202 ED I decided to try them for myself. To say the least I am very unimpressed. To start with the good:
My laundry machine sticker, in field center text is legible and CA well enough controlled:
At the top of the FOV there is much more CA but most text is still legible enough:
And lastly at the bottom, the blurring anomaly sets in.
My question is, was this behavior introduced by severe tilting of some elements to achieve collimation? Has anyone else with this model noticed this? I have been trying to return them for about two weeks now but they are balking asking for all sorts of verification photos of the problem but we shall see how that shakes out.
- Quite compact and lightweight
- Nice focuser with no slack
- Don't feel flimsy or cheap
- Adequate glare control
