  1. After an early run in the rain the clouds cleared and left me with an almost cloud-free sky by 11am. Be rude not to get the scope out really wouldn't it? Glad I did, loads of spot activity, some nice proms in HA and Ca-K as well as some nice surface activity in HA! White light full disks to kick off That BIG spot up-close with the 3x barlow A bit of granulation, just because I like it! Ca-K full disks and close-up on AR13363. I did take some footage of the prom at "9 o'clock" using the barlow but did not come out well at all. Close-up done using the 2x barlow in Ca-K due to seeing and breeze! And finally in H alpha
  2. Ooh, some nice granulation 😍 I must do some high res wl at some point. Great shots Pete!
  3. Finally got another session in. Seems we are either busy on weekends at the moment or it's cloudy / raining / thundering. I did actually manage to image on the 4th but had to rush out on that day and only found the unprocessed data on the laptop this morning! Surprised to see some half decent seeing today, despite having to wait until midday to image. The usual White Light, Ca-K and H Alpha full disks below. Still struggle to get nice flat mosaics from my Quark and this one is particularly dodgy. Looks like the bottom right pane was shot and processed completely differently, it wasn't!
  4. Nicely done. You still using the 1000D Steve?
  5. Clear skies early this morning and working from home today so had some time to grab some solar. Conditions were far from ideal with passing cloud and variable seeing. Seeing actually settled a bit towards the end of the session so I went back and re-shot the white light. Should have done the same with the Ca-K really but ran out of time.
  6. Nicely done Dave. Nothing but rain here,
  7. Nice pair Dave, if you'll pardon the expression
  8. Nicely done Dave. Weather not playing ball here 😢
  9. Love the "concentric prom ring" Ca-K / HA comparison.
  10. The weather certainly is a challenge. See you've not lost your touch though, great set.
  11. Nice clear blue skies this morning and no work for a few days. A little breezy but at least that helps the seeing a bit. A few clouds skipping around but I managed to grab 3 full disks and a big prom too. Actually starting to remember how I used to process these. Finally the prom in both Ca-K and HA
  12. I see you've not lost your touch Steve, great images.
  13. Hi All Been away for a while and not done any solar imaging since last October 😧 hence the title. The Sun is too low to image until the end of February and then it rained all March! So I couldn't resist a look yesterday with wall-to-wall blue skies. Managed to grab 6 pane full disk images in 3 lights (WL, HA & Ca-K) plus a nice big prom in Hydrogen Alpha. Enjoy, hopefully more to come if the weather allows.
  14. Day 2 of solar today, quite a bit more cloud about today so multi-pane mosaics were definitely off the agenda. Also quite a strong breeze, not good with a scope that's best part of a meter long! Still managed some half-decent captures in white light and H alpha. Ca-K was a challenge as the seeing was very poor at 393.4nm. First up a demonstration of why I did not shoot pano disks today Conditions changed in the few seconds between shooting the left and right panes leaving one side markedly brighter than the other. Still, I figured there was enough detail to be worth sharing. If anyone has any tips on how to "equalise" the panes of a mosaic in post-processing I'd be very interested! Had more success in H alpha although in hind sight I should have taken flats Quite please with this one, the inverted colours really make the features stand out. Liked it so much I tried it on the other H alpha shot Not the sharpest image ever but given that it was taken at 3000mm focal length on a windy day I am pretty happy with it. Finally a couple of white lights below which were also shot at the same 3000mm focal length.
  15. Rare purely because they don't work, see example below Apart from my apparent brain-lapse whilst capturing H alpha (captured 2 x top right segment and missed bottom right altogether) it was a nice session. Seeing was not bad at all and I managed to get setup so that the laptop and I were mostly in shade, which was nice
