  1. For any planetary imaging, the fastest frame rate that you can get is good. At least 30 fps You will need to push the gain quite high to get 40 - 100 fps For Jupiter, to keep it simple, aim for less than 60 seconds of video to avoid blurring due to Jupiter's rotation. Use PiPP and AS!2 or AS!3 to stack the best frames ( anywhere from 20% - 80%) depending on seeing and Registax for sharpening using wavelets (which is a black art in itself) Regards Neil
  2. What mount are you using?. Some (all?) Skywatcher mounts have the ability to offset the home by 90 degrees in Dec to allow for a side by side rig. Do the first setup with the handset, adjust the Dec offset to either +90 or-90 degrees, park the mount from the handset, switch off the mount, switch the hand set cable for EQMOD cable, switch back on and away you go. Works perfectly for my EQ8. Haven't used the hand set now since the last time I polar aligned the scope - about six mounths ago now Not sure if other mounts have this feature. Regards Neil
  3. Introducing... Heavy, sticky light

    Does this mean we won't need to worry about street lights any more?
  4. Feilimb -thanks for posting this -especially the references - I'm trying to do the same thing, so far only used Lightvortex tutorials, but got stuck. I'm hoping the addititnal stuff you point to will get me sorted. Neil
  5. Apologies for not reading Op properly - i thought he had a celestron SCT not a PST - which of course is a proper solar scope. however, my comment about frying the camera still stands. I have a very large black spot in the middle of my QHY5l - 'cos I forgot to cover my finder last time I did some solar work ;-)
  6. NEVER, EVER try to look at the SUN through a telescope without the proper solar filters!!!!!! And pointing it at the sun will most likely fry the starsense camera. Neil
  7. sol ha prom 19-1-18

    Serious envy - Sol doesn't get above trees here for another few weeks
  8. October 1, 2017: Finally some sunshine!

    Well done Michael,glad you got some sun - we might get some around Thursday. I guess the only consolation is that old Sol is q bit quieter this week.
  9. Sol WL, HA, Proms, loads of action 6-9-17

    Love that prom - envious - its cloudy here
  10. AR2674 & 2673 from 1st Sept

    A wide(r) angle view of both ARs on the disk ASIO1600MM-Cool at full frame, Quark, Opticstar 127mmApo, Baader 35nm filter as ERF MY, my - hasn't AR2673 changed over the last 5 days! And a close up of 2674 ASIO1600MM-Cool at 1/4 frame ROI, Quark, Opticstar 127mmApo, Baader 35nm filter as ERF I tried an animation of 2674, but quality wasn't good enough - image quality, colour, brightness all varied by frame. Any hints and tips on how to improve are very welcome. Regards Neil

    Nice. all cloud here :-(
  12. heads up new spot alert 30-8-17 "updated"

    Good stuff charl. Now just hope fpor some clear skies over next few days - at least its stopped raining here now
  13. August 29, 2017: 66-pane mosaic in H-alpha

    Min boggling. The dedication need to do this never ceases to amaze me. Superb work
  14. Saturday's ARs

    Hi Charl, - yep 2671 kept it interesting. Latest images on GONG hint at something coming over the limb - fingers crossed. Weather here on south coast not too bad - some high haze and the usual fluffy stuff. Hopefully will last another day or so before the rain arrives. But at least the skies are getting darker so its the start of the night time imaging too. At least DSOs don't generate so much data :-)
  15. Saturday's ARs

    Even here in the UK we can get to see the sun a couple of days a week - the imaging itself can be done fairly quickly - for full frame stuff(using an ASI 1600MM-C) I get about 15 frames per sec and take about 5 -10 videos of 1000 frames, for the closer stuff - 1/4 frame of the ASI, I get about 50 fps and takes 5 -20 videos of 1000 - 5000 frames - so timewise - 1 -2 hours per session. Mind you it generates anything up to 1/2 terabyte of data to process :-)
