I would like to observe RR Lyrae variable stars in the M5 cluster.

These images will be used for both research and educational purposes.

I would like to get 15 images per observation, for 7 observations in total. My ideal exposure time is 20 seconds.

I would like 10 of these images to be in the V filter, and 5 in the B filter.

It would be so helpful for me if these observations (or parts of it) could be returned to me by May 12. I would sincerely appreciate it if I could get around 15 pages nightly. It is completely fine with me if these images are taken during separate time periods or nights.

Expecting to get images within a few days (6?) of your proposal is unrealistic! If this is for a course assignment, you need to plan further ahead (e.g., 30+ days).

I am changing the date: anytime before May 23 would be ideal for me. Is it possible to run this plan a few times in the next two weeks? I do not need too many images. Thanks a lot.
