I've seen some of JJJ's pictures and starting to wonder...
Does anyone else have some photo's they have taken recently with an NG or Hioptic 127?
I had an NG CF127 last year but the image quality was dismal.
Pinching of some sort somewhere that i was never able to find. Resulted in triangles taken out of stars.
Excessive star halos is another problem - especially in the blue wavelengths.
Looking at JJJ's pictures i see her bright stars also have excessive bloat as if focus is soft/out.
I am not alone it seems with those issues. This site:

has a better write up on it, but it appears that the blue wavelength color corrections are sloppy and or chromatic abberations are quite high. This can be partly corrected with refocusing if using a mono camera with blue filter, but for a OSC it isn't an option.
I've attached two photos as examples. Blue star's stick out like a sore thumb. I've checked the stacked RGB raws as well and there is a noticeable star size difference between red and blue filters (and stars).
If anyone else has photos, it would be appreciated if you can post them to see if these issues were corrected in a newer batch, or not.
Cheers.
