    Question Observation sequence for Caldwell Catalogue



    Is there any observation sequence that one can follow to maximise chances of seeing as many Caldwell objects as possible? I am aware that objects from C1 to C51 can be seen from Northern Hemisphere & the from C52 to C109 belong to Southern hemisphere observers.

    For latitude 19 degree (Northern Hemisphere), is there such a sequence? & If so, where can it be found? Links plz.

    Messier Marathon does have a observing sequence, a similar observing sequence for Caldwell Catalogue needed.

    Ditto. As you get closer to the M70 or M100 it gets a bit confusing with all of the objects seen. You have to double check your list before heading out for a night of observing and make a definite plan. Having a suggested observing sequence would be highly useful.

    A reasonable ordering of the Caldwell objects is according to the right ascension (R.A.), like C2 (NGC 40), C72 (NGC 55), C106 (NGC 104), ...

    When planning my observing sessions in general, I make an ordering according to the R.A., and take as the first the groups of the objects above the southern horizon, or above the light pollution domes.

    Happy hunting,

    Unlike the Messier's, which are all over the place, the Caldwell's start near Polaris and work their way downwards.

    This doesn't answer your question but I just received a great book about the Caldwell objects that you might want to check out.
    'The Caldwell Objects', by Stephen James O'Meara

    (Yes JG, yet another book.)

    Thanks @hal2000 - that link shows Caldwell object visbility for given location.
    Thanks @j.gardavsky for the tip - start sorting using R.A.

    So combining the above two hints - one can have a reasonable observing sequence for Caldwell Catalogue. Thank you friends.

    Still, if anyone stumbles upon the sequence, kindly share it or the tips.

    Thats a find olddogg60, for a while Amazon had ridiculous prices on it for used. Great book with excellent sketches to show you what you can expect to see.

    Friends, I found this wonderful link The Messier Marathon Planner by Larry McNish it gives messier observation sequence. A similar one for Caldwell wanted!

    Yeah, I am glad I bought mine on sale back in the day when they were easier to find. I have the entire Dark Sky Companions series, except for the newest one coming out the end of this month (hopefully), Southern Gems. Even though I might not be able to see most of the contents, I enjoy reading his books immensely, and plan to get it as well. His books have pointed me in the direction of many objects I might have otherwise overlooked.
