  1. AstroTortilla - its free and its brilliant. The goto on my 10" LX200 is very hit and miss (mostly miss) so getting on faint targets with the narrow FOV after focussing my DSLR was a nightmare - I could literally spend hours failing to acquire some targets. AT plate solving gets me on target (centre of FOV) every time in just a few minutes.
  2. Good luck. I wish - I'm under a thick grey blanket here and I'm not referring to my bed clothes..... :-(
  3. Seeing as the Moon was up and I'd set up my 10" rig for what turned out to be an underwhelming try at Jupiter I thought that I might as well slew over to the moon and grab a few close ups... They are a bit grainy (from shooting through fog I think), but turned out better than my Jupiter.... Thanks for looking.
  4. Thanks Peter, I guess that I'd also pretty much given up on planetary too seeing as I didn't do any since may 2015 (and that was a single crappy Saturn :-( ), but I did some solar with my 4" in the morning and the seeing was pretty good at times, so I thought that I drag the 10" out...!! This might be the last year we'll get to do any (worthwhile) planetary from the UK for a while as they are all heading south, Mars is big this year but low, Saturn is an horizon grazer and Jupiter heading in the same direction.... :-(. Cheers, Geof
  5. Had periods of good seeing on the morning of St Patrick's Day, so set up to see what I could capture with the new AR 2524 just rotated into view. I stacked 4 DSLR (Canon 600D) images in AS2!, then used my ZWO ASI120MM-S with x3 TV barlow to grab some close ups of both AR2524 and 2519 Thanks for looking.
  6. Hi all, With the bulk of the jet stream out of the way I was hoping for good seeing so set my 10" Meade LX200GPS up to shoot my first Jupiter since April 2015 - I can't believe that its been 11 months..!! Unfortunately seeing was not so good, shooting through lots of moon illuminated high fog with a stubborn finger of the jet stream persisting over southern UK, but here is the result anyway.... The image is 12 minutes (best 40% of 12 x 1 minute video stacks for a total of 12,400 frames) processed in AS2!, Registax6, PS(CS2) and de-rotated in WinJupos. I'm not sure if the soft image was just seeing as there were no bright stars visible through the fog to check collimation and it really was the first time the 10" has been out since early summer 2015. Thanks for looking.
  7. Hi Stuart, these are excellent images. I also imaged Jupiter on 17 March 16, the first time since last year (18 April 15), God has it really been 11 months - the weather here has been Rubbish for months. I was expecting (hoping?) better seeing, but that proved not to be the case (here in Surrey anyway) trying to capture the end of the Callisto transit. As a newbie to SGL I'm not sure what the correct form is for posting images on threads so I'll upload mine to separate thread rather than backing into yours.
  8. Excellent capture despite the poor seeing. It was in my diary to go after it, but unfortunately it clashed with an early morning commitment on 8th which I couldn't reschedule and dare not risk over sleeping, so reluctantly I let it pass despite the totally clear sky. Great to be able to see it after the fact via your pics, so thanks for sharing.
  9. Hello to you too, seems like we've got the pincer move on London....
  10. Welcome. I've been interested in astronomy for well over 50 years (since I was about 7), but only doing it seriously for the past 4 years since I retired and only joined this group a few days ahead of you. This is already proving to be a great knowledge base with great folks so you definitely joined the right forum. Good luck with the hobby, there are so many aspects to it, from wonderful views, pretty pictures or real science....
  11. Thanks Dave, yes that is most definitely counter intuitive....
  12. Thanks Alexandra, I just took a peek at your Flickr site - stunning images...!! I have a long way to go, so thanks for the encouragement... Geof
  13. Thanks Dave, so do I just shoot the defocussed sun for flats? I'm not sure what the process is....
  14. Thanks Dave, I had enough problems trying to capture the 'light' data yesterday with all the cloud....!! I have a couple of home made light boxes which I use for my DSO flats, so presumably I could use them to create video flats - what do you think? Is the technique much the same as for DSO flats, e.g. how long and what exposure settings should the flat videos be taken? I also usually use AS2 for stacking, but for some reason (probably cloud) neither AS2 nor R6 wanted to play with most of yesterday's AVis, I just got very heavily 'boxed' images, so I ended up trying a video processing tool in ImagesPlus (IP), which is the primary software that I use for my DSO capture & processing. IP didn't have any problems grading and stacking the AVIs, so it was good to have that option as a fall back. Cheers, Geof
  15. Thanks laudropb, I think 'mono' is winning
  16. Flats, right I should have guessed that...!! I use flats for DSOs, but have never done that for AVIs - I tend to rely on the image moving around on the chip to average out noise in the imaging train, but then clone out the worst of any 'doughnuts', etc. that remain. Its never been a problem with my lunar and planetary imaging, so didn't even consider it for solar, but maybe I should give them a try. Thanks for the suggestion.
  17. Hi Michael, thanks for the feedback. I agree that adding colour does seem to make the image appear more noisy. I got the colour by adjusting levels in each of the 3 channels, so that may be the culprit. Sorry, but what are flays - I'm sure that I didn't use them...?!! Also I've wondered about double reflections as I do see that visually with this scope sometimes, but I was thinking that was reflections from the contimuum filter off the rear lens in the TSAPO which is a quad. I've found that sometimes there are 2 possible images on which to focus, a bright one and a much fainter one at a different focus point. Cheers, Geof
  18. Hi Craig, yep I'm sure that colour blindlness brings its own challenges. I also realise that colouring the data is totally subjective, hence the main reason for my question.... thanks for the feedback. Geof
  19. Hi Pete, Thanks for the feedback. The image came out a lot better than I expected. I was experimenting with the extension tube to the x3 barlow just to see what magnification it would give, but the raw AVi didn't look at all promising - just shows that you need to do the processing to really find out..!! Yes, I like to see a yellow Sun and have seen others do similar colourisation, but actually I like the B/W versions too, so not sure which way I'll go in future - maybe a bit of both... Cheers, Geof
  20. Superb..!! I'm just starting out with solar white light imaging, but an Ha scope is definitely on my 'some day' shopping list....
  21. Hi everyone, I'm new to SGL and also new to solar imaging having only gotten into it during Feb 2016. I'm using a TSAPO100Q with a home made Baader film filter, Baader double stack continuum filter and ZWO ASI120MM-S mono video camera. Today I took a run at the nice AR2506 (centre of disc), also using a TeleVue x3 Barlow + 60mm ext tube pushing the barlow to an effective ~x4.25. Data was processed in ImagesPlus software and PS-CS2. I thought that I'd mess around colouring it, so the attached image shows both B/W & yellow versions. What do you all think please - leave it B/W, or is either ok? Seeing was not great, shooting through a lot of fast moving haze, so glad to get anything... Cheers, Geof
