Notes: Spent a long time studying this field. A pair of 10th magnitude stars point to the galaxy’s location. Unable to see Arp 30 with DV, and AV only revealed an indistinct, roughly oval patch. I could not make a positive identification of the A & B components. There was no trace of the “one heavy arm” (which modern imaging has revealed to be a separate, edge-on galaxy). Looking at images, I am surprised the edge-on galaxy was not in range. Exceptionally I tried higher magnification with the 5mm Vixen LV Plössl. This eyepiece design is not suited to a fast f4.1 primary and I do not feel I gained anything. |
