Thank you for the compliment!
910 mm is the effective focal length of the telescope and did not use any converters or Barlow lenses. I applied a factor 2 scaling in the image processing while stacking the 80 images.

Jerry, I use a tracking mount and stack the heap of single exposures with an astro-software (free) to combine it into one image. The rest is done in Photoshop.
