I was wondering if it is possible to switch the capacitor which with two resistors forms the astable configuration in a 555 timer using a CD4051 analog multiplexer
Is it fine with you if a draw it?Welcome to AAC!
It depends on the circuit. Post a schematic so we can see if you'd be stressing the switches.
Any way you want to do it. Photos of screens are the least effective because of moiré patterns; screen captures are better in that case.Is it fine with you if a draw it?

Illustration is fine- just be clear and consistent in how you draw it, and label everything both with a label like 'R1' for first resistor, and it's value (whether Ohmic, Voltaic, Semiconductor or otherwise).Is it fine with you if a draw it?
Thank you for the advice, I really appreciated itConnect the smallest capacitor directly to the NE555. Then through the CD4051 add more caps in parallel to make larger values. I know you will have to do a little math but; The oscillator will run more stable. The effects of the 4051 will be less.

Thanks for everything.. appreciatedCurrent through the multiplexer will be less than 1mA, so it should work.

This helped a lot, thanksIt's in the datasheet. Worst case is 1300 ohms.
Resistance also depends on temperature and signal voltage.
