Hi Vikas,
Feel free to make a submission for this yourself. I'm sure you know what to do, but if you're not quite sure then select "STORE" from the top menu , then you can select "Book Time Syndicate", which offers you a choice of your syndicates for which you want to make a booking. Just enter M31 as the Object, and from "Select Filter", select the one(s) you want followed by the exposure time and finally the number of exposures. At the bottom of the screen you can can enter some notes if you want, then select "Submit Object".
Hope you are well and making good progress on your own rig.
Regards,
Ray
