I've tested it outside under real conditions and the camera shoots all the frames without issue including the burst of 6 frames. I know that it partly depends on your definition of Bailys beads but I'm struck by the C2 -06 versus C2 -12 difference.įor those interested, this is the script that SEM generated for me. I used Xavier's script to come up with this game plan and was successfully able to insert a burst of 3/sec and shoot multiple stops during Totality for the Corona.įor example, I see in Jerry's post that he shoots Baily's beads at C2 -06 and Diamond ring at C2 -03 then his chromosphere shots are at C2 +0 and C2+ 03 where as my xavier script is shooting Diamond ring at C2 -12 and Baileys Beads at C2 -1.5. I am using a Canon 7D with the fastest card I could find and I still need to keep exposures to 3 sec intervals. I was looking at Jerry's timings on his blog post and noticed that those generated in my script by SEM are significantly different. Hi guys, I'm a bit confused and sorry for the question if it is obvious. If you want more frames, you could try a shorter MLU, but you will have to test it with your setup.Įdited by Jerry Lodriguss, 09 August 2017 - 06:57 PM. ![]() That's what, only a 30 percent improvement? 4 frames would give you a 2x improvement. Two frames at each exposure gives you a 1.4x improvement in s/n. Plus, you will only be using the high s/n part of each image in the composite, so not having a lot of frames to stack is not a big deal. You shoot an exposure sequence at different exposures to composite together into an HDR image. You will have plenty of light here, and good s/n in each individual frame because you are shooting at a low ISO. Should I be happy? I was hoping to make an HDR compostion of totality but I see I'll only have two frames of most exposures, so there won't be much to stack. These were exposed with 3 second delay so half the totality set is the 19 frames. 8x FL reducer (435mm EFL FOV~4 suns x 6 suns). Just got these results running the SEM Wizard script with my Canon 60Da. I will keep experimenting.Įdited by andysea, 06 August 2017 - 09:55 AM. ![]() The only reason that I can think of is that the 5D4 uses a different DiGIC processor than the 7D. Perhaps that is OK as with the slow burst I can still get 3fps and spacing the clicks further apart will allow for spreading them out more during the progression of the phase. That is very strange I did include the CHGCSSL command before every burst, I even tried to space the events apart by a few seconds. I don't know why you are not getting the high speed burst if you include the CHGCSLL command before every burst. I corresponded with Xavier about this and he said that it is intentional behavior that he programmed in for the burst rate to revert to the slower one after the first high speed burst. The 7DII seems to be the best choice for this type of imaging. Interesting that you used CHGSSL before every burst. I'll try to space the bursts further apart. I tried both your scripts and I get the same behavior, first burst is fast then the other ones are at the slower burst rate. ![]()
