I think that is a good match. It gives about a 1.3x1.3 degree FOV with 1.5arcsec pixels, and the 533 camera can use 1.25" filters (with some corner vignetting), which are cheaper and you can get more slots in the filter wheel. We currently use the ASI183 camera on the AAVSOnet telescopes, but will be testing a 533 as an upgrade this coming week.
There are 2.3 million variable stars listed in VSX as of today. It is hard to suggest just one of them. I'm assuming you are pretty much a beginner. I'd certainly read through the CCD Observing Manual, and consider taking some of the CHOICE courses.
The E180 and its 1.3x1.3 degree field of view is ideally configured for brighter stars, as the wide field of view gives you a good opportunity to find a suitable comparison star for such targets. A good example right now is monitoring T CrB, predicted to go into outburst sometime soon. However, anything from about 5th magnitude to 13th magnitude is fair game, and perhaps fainter, depending on the crowding in the field, the tracking ability of your mount, etc. There is a whole set of bright stars that form the SNEWS project, monitoring them for years or decades, as these stars are the ones potentially able to become a nova or supernova in the future. Some dozens of times a year, the AAVSO posts an "Alert Notice" of a campaign to monitor some object for a researcher. These are also good choices.
So look around a bit. I'm sure that you will find something interesting to follow!

Apparently your ODK scope questions disappeared from the forum.
I have an ODK16 inch from Orion Optics UK since 2010. I use it remotely from Chile. The scope is OK for photometry but not good for astrophotografy as it does not hold collimation.I use it solely for photometry and since Aug. 1, 2011 it is generating tons of photometric images from the remote site.
Hi Sam,

Thank you Arne for your quick response.
Arne, which targets should I consider as a new individual with my 180?

Thank you Josch, for your reply. which camera do you utilize with your ODK16?
Hi,
I use an QHY600M CMOS camera on the ODK16 since May 2023.
Its true 16 bit and has an chip of size 24x36mm^2.
I use it in 4x4 binning which gives about 16 micron pixel size.and 7.5 MB file size.
