Davey-T Posted August 7, 2014 Share Posted August 7, 2014 Tried to do my first mozaic of the Sun today after receiving my 90mm front etalon apapter (thanks to Simon, Robin etal for the recommend)Just run the vid;s through RG6 and a couple of them have not come out right, not really sure if I'm doing it right in Registax but the others have come out OK.Here's a sampleDave Link to comment Share on other sites More sharing options...
David Smith Posted August 7, 2014 Share Posted August 7, 2014 This is why I use AutoStakkert. Will watch thread with interest though. Link to comment Share on other sites More sharing options...
Zakalwe Posted August 7, 2014 Share Posted August 7, 2014 Autostakkert all the way. It's easier to use, miles quicker and produces better results.once you've stacked them in AS2, drag and drop the file into Registax for wavelet sharpening.

Davey-T Posted August 7, 2014 Author Share Posted August 7, 2014 Well that went well, downloaded Autostakkert, tried to open AVI file and get error message failed to open file frame count 0, any ideas ?Dave Link to comment Share on other sites More sharing options...
Steve Ward Posted August 7, 2014 Share Posted August 7, 2014 Might pay to run it through PIPP first , this will reorder the frames by quality and export in a format that AS!2 will take. Link to comment Share on other sites More sharing options...
Davey-T Posted August 7, 2014 Author Share Posted August 7, 2014 Downloaded PIPP will try again tomorrow.Dave Link to comment Share on other sites More sharing options...
Davey-T Posted August 8, 2014 Author Share Posted August 8, 2014 Run one AVI through Pipp and Autostakkert and artefacts are gone that's a step forward, so thanks to all for advice.Just need to learn how to process the images now.Gave up on the moziac as it had a couple of bits duplicated and a couple of bits missing lol.Here's my hamfisted attempt at processing one frame of the "mozaic"Incidentally how much can the LS60DS be barlowed, I've only got a 2X at the moment.Dave Link to comment Share on other sites More sharing options...
Zakalwe Posted August 8, 2014 Share Posted August 8, 2014 What camera are you using?A x2 Barlow works nicely. You need good seeing to go much higher. I have used an x3 when conditions are good, and also tried stacking my x2 into my TV 2.5 Powermate. That was pushing it for my location.Mark Townley has some excellent tutorials on his site:http://brierleyhillsolar.blogspot.co.uk/p/imaging-tutorials.html Link to comment Share on other sites More sharing options...

Try and make the source data as good as possible, then every step afterwards is easier. High quality data is much easier to manipulate.I spend ages on getting the focus as good as I can. And I re-focus during imaging runs.Don't push the wavelets too far in Registax either. Additional sharpening can be done in PS (High pass filtering works well). I only ever use the first two wavelet sliders in R6. I make sure that Gaussian is selected, the select the Dyadic radio button. Slider one goes to near the max and slider two is about 25% along. All the others are on default. The lower sliders will blow the sharpening. Link to comment Share on other sites More sharing options...
Steve Ward Posted August 8, 2014 Share Posted August 8, 2014 Fully agree with the above , especially the focus , for my Whitelight I get it absolutely nailed , and then monitor for a minute before hitting the shutter , and I shoot in sets of 100 frames at a time but recheck every 30 or so , nothing worse than seeing perfect subs at the start of a set drifting slightly out of focus towards the end , particularly on very hot days when things get warm and expand a little during a session.With regard to Wavelets , I always knock the bottom four sliders right back to the far left to start with before touching the top two , really helps reduce the large radius blur and pull out the small fine detail ...

Davey-T Posted August 8, 2014 Author Share Posted August 8, 2014 Still planning on motor focuser when I get round to it, still not sure if it's tuned as well as it could be, mainly the front etalon. got TS adapter but not had enough sunny days to get it right,Tried wavelets in RG but made images worse so was probably doing too much.How late in the year is it feasible to Solar image ?Dave Link to comment Share on other sites More sharing options...
Steve Ward Posted August 8, 2014 Share Posted August 8, 2014 Put it this way , I've caught 192 days out of 220 so far this year ... if it's shining I'm shooting ... Link to comment Share on other sites More sharing options...
sooot Posted August 8, 2014 Share Posted August 8, 2014 Id guess seeing will be better in the cold less thermals to deal with. But ive not imaged during winter to really give an answer. The suns dropping rapidly now soon wont see it for half the day as theres a stupid tree line in the way. Looks like ill test the strength of the flat roof(yeah right) Link to comment Share on other sites More sharing options...

sooot Posted August 8, 2014 Share Posted August 8, 2014 I try to keep my gear a bit hidden were not far off the bronx around here. Only reason i leave gear out all night on its own is because phd has a hissy fit when scopes touched. And the .22 and dog would scare anyone away.
