I said I'd get back to all of you when I received the Intes Micro 603 we ordered. We haven't had time to test it on the interferometer, but that will happen in short order.
My first impressions; First, UPS did their usual smashing of the shipping box. It was completely mutilated. Luckily the scope itself is sent in its own padded case which helped protect it, sort of. Since UPS did such a fine job of throwing this item around they managed to knock loose the secondary mirror cell. So much for collimation.
The secondary mirror cell is held in place with a threaded ring. It is imperative to a user to make sure this ring is tightened snug. If you don't, the metal threaded cap that covers the collimation screw area, when turned to remove it, can rotate the secondary mirror cell. So don't put the cap on very tight or don't allow the cap to bottom out tight.
Visual inspection of all the parts; not the best anodize coatings of the black adapters I've ever seen. The included finder scope is ok, but is heavy and looks like military optics. The reticle was loose in the finder, probably from the UPS effort. The included padded case is nice, but the material inside has a tendency to collect hair. Mine looked like it was full of cat hair but cleaned up nicely.
The optical tube of the MAK had a paint chip right on the top. I don't think this happened from UPS, but since the scope is for work, I don't care. The structure of the scope is solid and built well, not like a cheap scope.
The focuser works good. It feels tight in some areas but I think it will smooth in with some use. Not much if any backlash from forward to reverse focusing, that is good.
The optics; I had to collimate it since UPS was so abusive. It wasn't too far off once the cell was tightened back down. Here's where I think the scope may excel. I used a LED with multiple apertures for a false star. It was daylight so I had to collimate indoors down a really long hall. Once I tweaked it close it became apparent that you could really dial in on the diffraction rings when focused to a pin point. I didn't notice any real flaring and can't wait to get it on a stable mount and work a small star at night. So in my lowly opinion, I believe the optics will be on par with the specs.
We'll know for certain in the next couple of weeks.
All in All, I'm happy with it for the reason we bought it, so far. If I was buying this for my own use I may have taken issue with the paint defect, maybe not. However, for the reason of the optics, I feel if you work the collimation to absolute perfection, then you'll see this scope will bring out some truly tight star pin points, almost refractor, but not quite, but close.
I'll follow up with the optic report soon. Joe
