So I've been on a DPAC binge during the miserable weather around here and this is my last one for a while.
It is my Intes MN76 Mak-Newtonian.
This scope has a much larger fully illuminate FOV relative to my APM/MW MN86 reported elsewhere in this forum, rocketing all the way up to maybe 5-6mm. But still small in absolute terms and, like the MN86, only less so, will not allow me to image the entire aperture with my current DPAC Ronchi screen/LED holder. So, I had to, again like the DPAC for the MN86, flip the holder over to see and image the other edge of the primary. I also switched over to a white LED source which is much brighter than the green one I traditionally use. This allowed me to lower the ASA (reducing grain) as well as increase the shutter speed to 1/3000 of a second (!), which basically "freeze frames" the image, removing any motion artifacts from hand holding the cell phone camera. These came out pretty good.
And speaking of pretty good, these optics certainly are! But again, I already knew that from my time spent over the last decade with this scope, except, I now have some actual DPAC data that correlates with my visual impressions and star testing. A mild, uniform circular zone (not seen visually in star testing) but otherwise very smooth surfaces for the entire system. A very nice edge and look how straight those bands are. These images are from outside of focus. I did not have enough in-travel left to image more than one fat line inside of focus but I really don't need to see inside focus to see what I want to see.
Visually, this scope does indeed render very sharp images and takes high power with ease (but like all newts, you have to nail collimation and control the internal thermal conditions of the structure and optics to take full advantage of excellent optics like this).
As usual, hover your cursor over the images to read their titles, and, as always, comments are welcome.
