First thing, your site Telescopius is my goto site before I set off for a night of stargazing. Thank you. There seems to be a problem with the observation settings specifically the date. I notice that the galaxy M51 rises above 25 degrees (25 degrees, my filter parameter) at 8:04 PM today from my location, March 6. When the date is changed, M51 still rises at 8:04 PM. When the date is changed by 3 weeks ahead, M51 still rises at 8:04 PM. Can’t be right. Thanks for looking into this.
