I checked my model microscope this morning. I do have the Celestron Labs CB2000C. After looking at the photos of the CB1000CF on my desktop computer this morning, I believe the model that I have is probably a bit larger, physically, than the CB1000CF. I purposely purchased the larger body because I liked the rubber gripped objective turret. The focusing knobs seem to be significantly larger on my model as well.
According to the specs on Celestron's website, the CB1000CF does indeed have DIN 160 objectives so that is good. I know some of the sub-$100 beginner scopes do not have swappable objectives but, then again, those microscopes aren't meant for upgrading.
I should also correct an error in my previous post about the Celestron Microscope Imager. I wrote that I had a 10mp one but I checked this morning and it is the 5mp one that I have. They don't even make a 10mp one! Regardless of image size, I didn't like that camera which, I assume, is due to the old and tiny Aptina sensor. The Celestron software for it is rather quirky too. If you have a cellphone, I suspect that would produce far better images than the Celestron Imager.
As I wrote, above, I replaced my objectives with PLAN objectives, I replaced the bulb, I replaced the eyepieces and I added a more appropriate trinocular adapter tube that works better for my particular camera. These upgrades probably doubled my initial microscope cost (or a bit more) plus I wasted money on that Celestron Microscope Imager. On the positive side, I can always use my new eyepieces and objectives in a new microscope but I probably would not because I would keep this one as is for the grandchildren to use.
I have no regrets about purchasing this Celestron Labs microscope but I knew I would be interested in this hobby. If, after spending all that money, I found that I don't really have any interest in microscopy, I'd regret my purchase and wish I had just started small. In my case, I really should have gone for a microscope in the $750-1000 range right from the start.
Would you be happy with the CB1000CF? I can't judge that. Part of it depends on your budget. Part of it depends on your expectations for imaging quality. Part of it depends on your desired specimens. Part of it depends on which direction you want to go in microscopy. Part of it depends on your experience level with microscopes.
What I can recommend is a pretty good source of additional information about microscopes and microscopy. On YouTube, a guy who goes by Microbehunter Microscopy has a lot of informative videos.
I hope this helps.
