Is this possible? I have not made my first observation and would appcriate the benefit of your experience before purchasing filters.
Can I begin without filters?
Also what filters should be used?
If current valid information is found in your documentation please point me in that direction.
I both a CCD & CMOS camera.
Thank you
Steve
If you are just starting out observing for the AAVSO, there are many things to learn! I wouldn't worry about a filter until you have the data collection and reduction under your belt. Data sent to VPhot if done with no filter would be classified as CV, Clear and referenced to V.
For eclipisng binary observations you don't even care about filters: the main goal is to establish the time-of-minimum.
If you CMOS camera is color, with a bayer array, then you automatically have 3 filters! Take a look at DSLR manual in the main menu: Observing/Observing Manuals
If you get the bug to do photometry then start with the V filter, then add in B and R. With these you will be ready to add really useful data to the database.

Thank you very much. I am retiring Nov 1st and look forward to immersing myself in the hobby. I just bought David Levy's book and have been reading that. Thanks again and I look forward to participating and contributing.
