It is well worth setting your alarm clocks to observe this comet 🙂 This image was taken this morning well before breakfast. I must admit to telling them that I observe the Zenith quite often, both visually with the 24″ and also with the CCDs.
My understanding is that lasers can damage CCDs as well as eyes. I just did some searches on the internet to double check on this and found some confirmation of this. http://www.laserist.org/camera-sensor-damage-thesis.htm is one example.
I received the request too. I will fill it in, but I think that they got the tea lady/man to design it. 🙂
Thank you Nick. After hearing about Terry’s discovery I checked out “The possible Comet Confirmation Page” http://www.minorplanetcenter.net/iau/NEO/pccp_tabular.html and listed the emphemerides to get basic time and location info. I dual imaged with both the C14 and the 4″ F4 Pentax, starting when the comet was 4 degrees above the horizon. As it turned out the RA&Dec position in the emphem. were about 10 arc mins out, so it was off plate for the C14, but on for the Pentax. It was a devil of a job to find it on the low resolution image even after stacking with Astrometrica using the “/min & P.A. motion info from the site.
Note for some: All though not obvious you can backdate the emphem by putting a negative number in the :
Start ephemerides at now + hours
I have a Pulsar Dome. It is lined with ceiling tiles on the inside. No condensation. Around the outside bottom edge there is a six inch curtain made of roof liner. This reduces the amount of low cloud getting in.

Check to see what format you are saving the FITS file. 8 bit, 16 bit, 32 bit or IEEE Float. With the first three you can choose between compressed and uncompressed. Some of the programmes I use refuse to recognise any that are not IEEE Float.

Just to add my penny’s worth 🙂 . When I take my darks, flats, flat darks and biases they go into a dated + info directory. For example if I am taking them for the C14 (no focal reducer) using the SBig ST8 then the directory could be 20170126_DFB_C8. This helpful for when I go back to old observations and I want to start from scratch processing them again. I keep all my raw files, all the individual Flats – Darks – Flat Darks – Bias frames, as well the calibrated ones.
Just a 10 x 60 secs with the 4″ F4 and an ST8. Seeing was good.Observers: Tony Angel & Caisey Harlingten
I do agree with you that the Journal should include constructive Letters on Papers. Perhaps until that comes about, an interim solution would be to have a JBAA Letters section in this Forum. I would find it difficult to believe that there could be any opposition to this idea.
This was interesting. I enjoyed it very much.

Nick,
In my annoyance I forgot to thank you for the videos. I know that you put in a lot of hard work in producing these. I, along with I expect many others, really appreciate them. I have downloaded them all to watch, some of them a number of times.
Tony.
Nick.
I appreciate what you are saying, but because the method of communicating was changed – without notice -I did not even get the chance to apply. I cannot understand why they changed the method which I was depending on. At this time of year – harvest time – when every one is out in the fields all the daylight hours, I was “lucky” to get the Journal yesterday as sometimes it can take a month for mail to get from the Post Office to me. For other people, they could have been away on holiday – or working away – for a few weeks relying on their emails to keep them up to date.
After all the organisation and money I had put into making sure that I could attend this year I am still cheesed off.

I received that today. I have only just opened it . Living on top of a mountain mail is not regular. I can get written proof on this as a Spanish neighbour passed it to my daughter at 1330 hours. The Post Office delivers once a week to a few farms in the area
Why change the system without notice?..
First let me say how good the meeting was. No, that is wrong it was a brilliant meeting with perhaps the best combination of speakers and content I have seen at a Christmas Meeting. I also enjoyed meeting up again with so many and only sorry that there was not time to chat to more.
Second I would like to thank the many people who told me that they agreed with me on the matter raised above. No one came upto me an told me that I wrong, though perhaps some where just being polite 🙂
Tony.
I accept that I should have read my emails, journal and the website at the proper time. I will come to the meeting and pay at the door.
One of the things that I used to enjoy with the BAA is that the meeting were cost free with no hidden extras. For most of my membership time costs never affected me personally, but I recognised at the time how good this was for the less well off members – especially the younger ones. It meant that provided they could get to a meeting there were no further costs involved. At least it was not like some organisations where there are compulsary costs like ebtry fees and expensive snacks that you had to pay for, you could just turn up with a pack of bread and jam.
I will be looking into how to raise this issue of keeping the meetings free to members. Obviously anything held in the RAS rooms are free as no costs are involved apart from perhaps for a cup of tea or coffee to go along with my jam butties.
Tony.
Nick,
I agree that for a popular meeting it does make sense for members to indicate whether they are coming, though I would not book a place unless I was 100% certain that I could attend. That is why I waited until I did to attend.
I had not read the email, but I fully expected that the rules would have been the same as 2014 where the email said:
It will be free to all BAA members and affiliated society members if booked
in advance and for non-members the cost will be £5.00. If you turn up on
the day having not pre-booked the charge will be £5.00 to all.It is reasonable to expect that it would be the same this year.
Tony.
Jeremy,
I have attended most of the Christmas Meetings for over twenty years and enjoyed most of them. I tend to just scan email headers and did not read the specific one. Even if I had read it in time it would have made no difference as it has only been in the past few days that it was confirmed that I could visit the UK and I would never book until I knew a 100%.that I could attend.
I can understand the need for advanced booking, but I can see no reason for charging members. This means that members are paying twice.
What is the point of being a member when there is a potential charge equal to the General Public. Even though I will be in the area I cannot see how I can attend because even if I have the fiver as money is not being taken on the day.
I hope that in future years members will not be charged.
Tony.
