Actually I have an interesting object in Octans.
It isn't all boring.

Alp Oct is a 5.15 mag star that is catalogued as an EB star and a spectroscopic binary. The EB period is 2.88 days on very minimal data but the spectroscopic period is 9.03 days. There is clearly an error. I have measured the spectra and found a period of 2.87 days so the SB data seems to be incorrect. You can always find something interesting even in dim parts of the sky.
Thanks Terry. I managed to dig out a few more interesting things in Octans. δ Octantis is Saturn's southern pole star. BQ Octantis (mag6.8) is only 14' from the SCP--much closer than sigma. There are two stars in Octantis with known planets.There are a few binary stars. As you say, there is no part of the sky that is uninteresting.

I have to ask, how difficult was guiding near the pole, I tried and failed guiding close to the SCP.
Thanks Bill. I didn't have any guiding problems with this one. Perhaps it's because I have a very accurately polar aligned permanent setup.
