Holmberg VIII is classed by NED as IAB(s)m while UGC 08314 is listed as Im:. UGC 08314 has a redshift distance of 54 million light-years, same as Holmberg VIII. Since it is closely tied to NGC 5033 out of the image which many sources say is 40 million light-years away that is more likely the correct value. It has an odd vertical structure in the middle and then a large very faint western half. The eastern side has more bright areas and a small dim one to the northeast. A very unsymmetrical galaxy indeed.
A bright blue blob inside of Holmberg is identified by NED as SDSS J131318.46+361210.6. While listed as a separate galaxy it looks to me to be just a star cloud in Holmberg VIII. I've listed it in the annotated image. It does show a very slightly smaller redshift but I don't see that as sufficient to call it a separate galaxy.
It seems every field I image has some discrepancy when I dig into my research. This one is especially surprising. To the west of Holmberg VIII is the galaxy group SHK 248 with 9 members at a distance of 3.15 billion light-years. The problem is a possible member on the western side. NED shows two designations for it. SDSS J131210.13+361112.1 is at the right position showing a distance of 2.32 billion light-years. Too close to be a member. It's magnitude is in close agreement to my measurement, 18.6. NED also lists 4" of arc to the northwest at a position where nothing is seen, even on the Sloan survey image, 2MASX J13121012+3611117 a galaxy at magnitude 19.4 at a redshift distance of 3.15 billion light-years, correct for the group. It's position is listed with an error circle of 1", insufficient to overlap the only galaxy in the area. I tend to believe the Sloan data placing it too close to be part of the group.
