    Default The Roslund Summer experience



    In 2014 the seven Roslund starclusters in Sagitta, Vulpecula and Cygnus were a real summer-hype on the Dutch astroforum I am member of. The sport was to sketch, photograph or observe them all in one night. They are real summertime objects, some of them observable with bino's, others with small telescopes and a single one with a 10 inch telescope. They are photographed, described and sketched several times on German, Dutch and American fora. Roslund star cluster

    They are quite nice and easily done within one session. And rather close to each other. That makes it attractive. Number 5 and 6 are visible with a bino. Number 4 is quite a challenge with small apertures, but has two neighboring IC's as an extra. By far the biggest and brightest (and most beautiful imho) is #5, and easy to find. Very near Sadr (Cyg) four degrees south of NGC 6888. I observed Ro 5 with several instruments and found it very impressive in a 102mm Maksutov and refractor.

    Hereby a short list:

    Number Constellation Number ** Lucida Mv. Dim. RA DEC in ° and ' IDSA page
    Roslund #1 Sge 20 9 3' 19h 45m +17 33 42
    Roslund #2 Vul 20 7 14' 19h 46m +23 57 30
    Roslund #3 Sge 20 10 5' 19h 59m +20 32 29
    Roslund #4 Vul 30 11 5' 20h 05m +29 16 30
    Roslund #5 Cyg 120 8 50' 20h 10m +33 49 29
    Roslund #6 Cyg 30 7.5 24' 20h 29m +39 22 17

    BTW, here is the site I like to use to look up DSOs, including obscure catalogs like Roslund.

    https://telescopius.com/

    You can export your search results as Excel file, and you may tailor your observing lists by observing window, location, altitude above horizon, magnitude, size, SB, etc. It has DSOs images and other useful tools.

    Hello John,

    you have seen all Roslunds, eye can see:

    Roslund

    As a by-product of a survey of stars of high luminosity in the northern Milky Way, Curt Roslund of the Warner and Swasey Observatory published a list of 7 new clusters, all located in a small region in Cygnus, Sagittarius and Vulpecula.

    Bibcode (1960): [1960PASP...72..205R] Remarks on Some New and Some Known Galactic Clusters

    Hi John. I am aware of the Messier lists, the NGC (New General Catalog) list, the UPC (Uppsala Catalog) list, the PGC (Principle Galaxies) list, the IC (Index Catalog) list, the Burnham's Dark Nebula List, and also the Sharpless and Abell lists. This is the first time that I learn of the Roslund starclusters list. Thanks for your excellent and informative post John, and the best of regards.

    Hello Marshall,

    there is a mass of lists of the open clusters beyond NGC and IC.
    The open clusters have been intensively studied, and many new discovered, as they are important for tracing the structure of our Galaxy.

    Attached is the snapshot of the list of catalogs of the DSOs including the OCs in the STAR-Guide Atlas,
    some new discovered OCs and their candidates are in the IDSA.

    Best,

    Last evening I started again with Roslund 5. It is a very nice cluster. The main stars seem to be in a sort of squarish position to each other. The cluster seems to fill my 1.7 degree field at 30X in my 30mm Eudiascopic eyepiece. Several neigboring stars which are not member of the cluster do seem to belong anyhow . It is hard to say which belongs to the group and which doesn't, the stars have no sign on them. So the cluster seems larger than the 50' stated above.
    The Roslunds are absolutely no concurrence for the Messier clusters, but have a beauty of their own.
