The T490B features a unique simul-focal optical system with an adjustable trinocular port to enable well-focused clear images on your computer or video screen while simultaneously obtaining sharp, focused images through the eyepieces. Most trinocular microscopes allow you to view either through the trinocular port or the eyepieces only, forcing you to switch between the two. Since these trinocular ports are not simul-focal with the rest of the microscope optical system, you have to re-focus the microscope after each switch. The T490B, however, erases this step by providing simul-focal viewing. Especially handy for teaching demonstrations, clinical examinations and laboratory applications, the simul-focal feature allows your students or colleagues to view clear images simultaneously while you work through the eyepieces. In addition, the T490B's industry standard 23mm photo port can be converted into a C-Mount port, allowing you to attach most microscope digital cameras and video systems on the market. The T490B includes a 30-degree inclined 360-degree swiveling trinocular Siedentopf head, a 3-D mechanical stage, and an intensity-variable halogen illumination system. This versatile microscope is also capable of being upgraded with various accessories and attachments listed in the optional section for additional functions. It is a perfect laboratory instrument for clinics, Vets, Doctors, and professional students.

If you're buying this as a non-professional, curious person I would recommend a stain kit with a variety of stains, microtome, pipettes, extra slides (both with depression and flat), slightly more slide covers than slides, pre-moistened alcohol pads, and lint-free wipes (I like KimTech).
Attached to the review are some sample shots I took with my phone through the eyepiece, I hope they help because it was an frustrating ordeal to get them. Again, the camera mount and available imaging unit could use some more love, price-wise.
The ability to attach a video camera/camera via the monocular port is an awesome feature. Canon cameras can attach without the current adapter if you purchase a Canon specific adapter by Amscope, which cost around $90.
My major dislike is the lighting. It works ok, but I personally find it not bright enough. I also found that the higher resolution I want to go, the light becomes duller, though still functional. The lighting is classic halogen, not LED, but I knew that when purchasing. Only a month afterwards did I have an opportunity to use an LED microscope. Boy, that lighting will spoil you. The LED lighting is super bright, producing a pleasant viewing experience (makes for better microscope pictures too). The super power efficient LED lasts for a long time with no heat build-up like a halogen. But behold, if you Google 'microscope led hack,' you should find a few sites on how to LED your microscope. Amscope also sells an LED microscope light attachment for $30 bucks, which I think it can be used (or hacked) for this model.
You may find the microscope light fantastic as it is. It does work fine, but I personally think it could be better, since LED is a more quality light and actually cheaper than halogen. It also seems that LED technology is now becoming the standard lighting in modern microscopes. Ever lived in a house/apartment with standard incandescent bulbs and you noticed how everything became vivid-like after changing to fluorescent bulbs (or even LED)? That's the similar effect you'll find with a microscope with LED.
The star rating is 5 stars for the microscope, and 4 1/2 stars on the light. OH, for beginners, don't forget to calibrate (or adjust) your light/diaphragm on the microscope. I don't think this is quite important, as it was never taught in lab. It is like a 1 minute process that involves placing a paper under the light (one of the methods I came across), and adjusting other stuff like diaphragm to get a clearer, defined view. Doesn't hurt. Google 'adjusting microscope' or some type of variation like that.
