IC 1698 has the wrong comparison star name, but the correct position, listed in Javelle's table. The star is actually BD +14 215, not BD -0 217 (that is the comparison star for IC 1697). Note that IC 1699 (which see) is probably a second observation of this galaxy.

IC 1699 is probably a second observation of IC 1698 (which see). There is no nebula at the offsets Javelle has published, nor are there any at the offsets implied by changing their signs. However, if the north polar distance offset is changed to read +0 arcmin 49.6 arcsec (from +5 arcmin 49.6 arcsec), then IC 1699 would fall within Javelle's usual error range of IC 1698. The two observations of I1700 show this pretty well -- his offsets for that differ in RA by 1.13 seconds and in NPD by 5.9 arcsec.

IC 1699 is sometimes taken to be UGC 978. However, that has a lower surface brightness, so would have been more difficult to see with a long-focus refractor. Also, Javelle's published offsets would have been around +13.8 seconds, and -1 arcmin 22 arcsec (NPD), nowhere near the numbers that he gives.
