  1. Hi and welcome to SGL If you want to find a local society just plug your postcode into this page https://www.firstlightoptics.com/locator.html Hope you get it sorted - an 8inch dob will be fun to use! Helen
  2. It is a really nice little scope I've got one which is on loan to a friend's son and we've had a lot of fun with it. It can be tweaked to improve performance (eg the light shroud, and some plumber's tape on the helical focuser just to remove a little slop), but for the money it is really good! @Mark at Beaufort uses his tube on a different mount too. Helen
  3. I'm at the BAA comet meeting today Anyone else here? Helen (you'll easily find me as there are not many women here )
  4. You can update the software on the synscan handset I'm on my phone so tricky to link, but google it and you should find it Helen
  5. Yes The synscan handsets with latest firmware run on both eq and az mounts. I use a synscan v3 from an eq3 on my azgti with the appropriate cable. Helen
  6. Awesome was the word that immediately sprang to my mind too ! Helen
  7. And this is a play with the non-powermate data from the little celestron 274 camera - haven't used the stretch setting on IMPPG before! Thsi hasn't had the photoshop treatment as I quite like it as it is! Helen
  8. So I needed a change of focus this afternoon (PhD probation process is stressing me out!!) so as the sun was popping in and out of clouds I thought it would be worth a go. I was using the solarscope 70mm filter set on a WO 72. I started with the celestron 274 camera, and then a powermate, but there were so many dust bunnies (despite cleaning) that I gave up! But the activity made it worth trying something else. So grabbed the asi1600 mono from the obs, and stuck it in a 2.5 powermate and off I went (in little bursts between clouds...) The combination of big field of view and power worked surprisingly well - still a full disk ? The downside is full frame kills frame rate down to 3 fps ? Stacked in as!3, sharpened in imppg, and finished (including false colour in photoshop). Click for higher resolution. I'd be interested in advice on whether I should bin on the asi1600, and whether a bit of scaling down post-processing might work too. Thanks Helen
  9. Wishing you luck Tony! That sounds like a similar set up to the mobile one I’m working on ?. I will be interested in how you get on. We were very close to you today - lunch in the Cider Mill and then a walk along the canal. It was a lovely day to be out. I’m hoping tonight will be good too ? Helen
  10. @coatesg That's nice Graeme! There can be a challenge with getting a full run sometimes (I had the same issue with comet rotation observations), it can be scheduling or cloud/technical issues. There is a way of upping the priority if there is an important event, but it 'costs' time (ie you give up a bit of extra allocation for the priority). Given the amount of headroom in the allocation that might be possible to get a nice complete run of a particularly interesting object. Let me know if you'd like to pursue it and I can explain how to do it. On the more general issue of what else might be imaged, the feedback from the FT team is that they are looking for data sets which can be used in resources (where the underlying physical aspects will be explored and described). These resources are likely to range from simple plotting of already measured data, through to doing the photometry, plotting the graphs, looking at 'examples' of different variability and determining which ones fits the data, and finally making measurements based on the graph characteristics. So data sets that will show clearly the varying profiles of different types of variability would be great (including short period and long period etc). Data sets taken on different telescopes, and/or potentially with different filters (where variability might also include colour) would also be good. Students could see how different scopes affect the results. What would also be very useful is getting a list (and demo observations) of stars with different periods., visible at different times of year. This would allow FT to say to teachers 'if you want a project where data collection can be completed over x hours/days/weeks in this month then try these'. Part of the challenge is to choose stars where the field isn't too crowded so that differential photometry is straightforward. And of course choosing stars where the variability is big enough to be clearly seen in plots. If as well as getting these data for schools they can be used for research/submitted, and you enjoy doing it too, then it really is win-win-win! Have fun! Helen
  11. Nice link - thanks! I need something for my dob ? Helen
  12. The 16mm UWAN was my first premium eyepiece, and I still love it 10 years on! I then bought the 28mm, which again is lovely (although hand grenade size!). I completed the set a couple of years ago with the 7 and 4 mm in the Nirvana guise when they were on offer. I think they are all amazing value for money! Enjoy Ben ? Helen
