Hydrogen Alpha: Lunt 60mm Solartelescope + Lunt 50mm front filter for double stack.
Extra equipment: 0.5x focal reducer, 1.5x barlow, 2.5x Powermate
Camera: DMK31AU03 USB Mono


0.5x focal reducer - HDR from 3 exposures.


Alternative of the above.




1.5x barlow - Mosaic of 9 images.

1.5x barlow - Mosaic of 17 images.

I tried to do a HDR of this mosaic. I used the images from the mosaic of 17 images to get the proms.
Then i took the images from the mosaic of 9 images and saved them with gamma 0.50 in Registax6.

So only the 2 first ones are actual exposures. The last one is a fake exposures, but it works.

Images with 2.5x Powermate:

I captured 3 exposures for each area in an attempt to make HDR images out of them.


But it resulted in uneven illumination.


I then tried to see if i could trick the HDR program to make a more even illumination. My first try at it worked.

I did this for each exposure. Mirrored the exposure left and right and then mirrored those 3.


Then it was just a simple matter of cropping.
