Was this also with your 80mm frac, Graeme? Really shows what’s possible with a small scope plus CCD.
I wouldn’t worry too much Darren. For photometry try what you have at hand first before shelling out on more stuff. If you want to go to the nth degree in photometry you can try something else later. If it helps, I generally run my CCD camera 2 x 2 binned for photometry. There is nothing inherently wrong with binning.
I just updated the LC with data up to 2021 Jan 2. The last data points hint that might be beginning to fade a bit faster. Keep watching!
When making this plot, I was struck by the undulations in the LC at ~daily intervals. I’ve not looked into whether these are artefacts or genuine.
A quick reminder that we are only a few days away from the next superoutburst of IX Dra (perhaps 3 to 7 days). Hence observations are encouraged.
I had it at mag 17.1 last night (NY Eve) – just declined from the last “normal” outburst”. The next outburst could well be the super…keep watching!
Nice work Hugh.
There is also a paper by Mark Kidger on Betelgeuse in the December Journal.
The original Betelgeuse Forum thread you mentioned is here.
Here’s a light curve of the Nova which Philip Jennings just showed at the BAA meeting.
Prepared yesterday (Dec 4). Latest obs early this AM put it at mag 8.9
Still bright – last evening I had the nova at V~8.3. Technically this is an easy binocular target, especially now the Moon is receding.
You need a smaller telescope, Nick! I was using 5 sec exposures on the C11.
Good target for visual observers even with relatively small instruments.
Super to have another northerly nova.

Charts and sequences of the transient are now available from the AAVSO website.
The team responds to criticism of their announcement of phosphine discovery here. They say the ALMA data support PH3, but at lower concs than previously claimed. Standing by their conclusion, they call for further data.
Willmann-Bell shutting up shop is a sad development. The AIP4WIN software, which accompanies Richard Berry’s book “Astronomical Image Processing”, has been used by many people for photometry. The second edition, including AIP4WIN version 2 software, has been out of print for many years. According to Willmann-Bell, they are making a non-registered version available from their website, specifically stating “AIP4Win2.0 No Longer Requires On-line Registration”. Richard Berry comments in an AAVSO forum that it is now essentially freeware.
