Hi Mike,
Those are great looking spectra and an interesting comparison. Nice to see the BAA collection being put to good use.
If you fancy taking things to the next level then there is a wealth of free spectroscopy processing software now available. I’ve used BASS and ISIS, but there is also RSpec, Vspec and I think maybe a few others. These can produce a graph of a spectrum and help you to identify elements, along with various other functions.
I’m still a bit of a beginner in spectroscopy myself, starting out in September last year, but if you want pointers to any of the software then please let me know.
Do you know about the BAA spectroscopy workshop on 10th October at the Norman Lockyer observatory? It is being organised by the Variable Star Section noting it is more about an introduction to spectroscopy rather than variable stars.

Hi Donald,
May I also welcome you to the BAA. I became seriously interested in astronomy at around the same time as you, just over 30 years ago when I was 11. Jeremy has given you some excellent advice which I completely agree with. I find being involved with observing sections to be the most rewarding part of my BAA membership. You certainly don’t need to be an expert and there are plenty of people in the sections willing to offer help and advice.
As a variable star observer myself I concur with Jeremy that your equipment is ideally suited to making variable star observations. Although much useful work is done with CCDs and DSLRs, variable star observations made by eye are still of immense importance and value. Indeed the Variable Star Section has more active visual observers than CCD/DSLR observers.
Using binoculars or a small telescope to observe variable stars is a great way to use and improve your knowledge of the sky. I have a few variables that I follow with binoculars when I don’t have the time to do imaging or just want a relaxing observing session looking at the stars.
I’m sure any other section would welcome you too. The Comet and Deep Sky Section spring to mind with your equipment.
It is worth pointing out that next Saturday, 27th June, is the Exhibition meeting in Cardiff. If you are able to attend then it is a great place to see the work of the different observing sections and discuss how best to start contributing observations. That is how I started out in variable star observing, when I attend an exhibition meeting at Cambridge back in 2001, if my memory serves..
Best wishes,
Andy
I’d have to say that it looks a lot like an aeroplane vapour trail being illuminated by the setting Sun. A nice picture of one but in my opinion it is not a meteor or other astronomical phenomenom. Others have posted similar thoughts on the Bristol Post website.
Cheers,
Andy
Robin,
Stunning results. To obtain spectra of supernova down to mag 17.5 is really very impressive. Especially as you cannot directly see the target for guiding but have to work out the offset from a visible star.
Best wishes,
Andy
I too was at Longyearbyen in Svalbard for a fantastic eclipse. The corona was particularly impressive though my photo does not do it justice. I also saw the shadow bands both before and after totality.
By the end of totality my toes had gone numb with the cold and I had to do some jogging around to return the circulation!
Here is an image I took with a Canon EOS 450D and a 50mm lens.
We also saw a sun dog as totality approached. In this picture you can also just make out a balloon that took off at around first contact. This image was taken with a handheld Canon IXUS 220 HS.

Hi Dave,
Welcome back to the BAA! I’m the VSS database secretary so I’m sure we have a lot of interests in common. I too got seriously interested in astronomy when I was 11, all of 30 years ago now! That must have been around the same year..
Although we have programme stars, we welcome observations of any variable star. The VSS has a new online submission system for variable star observations which went live in February this year, and that will accept observations regardless of whether or not they are on the VSS programme. I know Tony has been uploading a lot of the SPA observations onto the database.
Good to make contact and I look forward to meeting you sometime.
Andy
