Sun in HAlpha With Lunt LS100THa Uploaded 12/26/20 Daily Report For Sunday, December 26th, 2020
Images below are 1290 wide and non clickable
An experimental shooting session for sure! I tried some solar imaging with my ZWO 120 mini autoguider camera to see how it compares to the DMK51 which wont run in Windows 10 - only win 7. The chip is about 3/4 the size of the DMK, but has more pixels. Images here are shrunk from the 1900 width of the originals to 1290 here to fit your screen.
Overall, the camera did well, but not as good as the DMK51 which has a higher frame rate, better contrast and more gamma adjustment range. Still, these are not bad for a quick set of test images.
Halpha:
Lets start with the full disk view, constructed from two frames pieced together as the chip was too small to get the whole disk in one shot. Quite a few proms present today, and for sunspot groups.
Here we will now use the 3x barlow and zoom in the the active regions
Finally, it takes much longer exposures to capture the prominences on the limb. The disk would be burned out, so I blanked it like an eclipse would to see it more clearly:
