    Object of the Week September 10th 2017- IC 1365 Compact Group of Galaxies

    IC 1365

    Type cD galaxy

    Equuleus

    RA

    Dec
    +02 33 53

    Mag 14.6

    IC 1365 is listed as the cD galaxy of a compact group in the small constellation Equuleus. It was found by Edward Swift the son of the famous Comet hunter Lewis Swift on September 28 1891 with his fathers 16" Clark refractor at Echo mountain in California. Edward swift is the youngest contributor to the NGC and IC catalog.

    I was recently in the San Francisco bay area visiting Steve Gottlied and he arranged for us to tour the Swift telescope at its home since 1942 at Santa Clara University. I have been wanting to see the 16" Clark for years. We had a wonderful visit with the old scope. It was exciting to me to be so near the telescope that had found so many NGC and IC objects. I was sad to learn that the dome was sealed shut and the scope was inoperable. I hope some day that this historical telescope will be able to see the stars again!

    I took a look at this group with Paul and Debbie Alsing's 18" reflector in the wonderful dark skies of the Steen mountains in South East Oregon recently. I was only able to see 3 of the 4 members.

    I took a look tonight with the 48" under very windy conditions. It was hard to split the two galaxies in the middle at 375X. That is why I did not see them with the 18". When I bumped up the power to 610X it was easy to split the pair in the middle. it was a nice view with all of them in a faint halo. The galaxy to the East is the dimmest of the 4. I did get a pop or two of the very faint galaxy that is NW of the center galaxy. The Edge on Galaxy (2MASX J21134684+0233497) west of group was easy to see at all powers.

    If you are a fan of compact groups like me be sure to give Edward Swifts IC 1365 group A GO! and be sure to LET US KNOW.
