The Astronomik Ha 12nm CCD clip filter has given new life to the old M42 lenses I have lying around. I wanted to see how the 300mm f/4 Pentax Super-Takumar would perform in Ha and it looks promising. Disregarding the noise, I jacked the unmodified Canon T6i's ISO to speed things up, and the North America Nebula / Pelican just jumped right out.

This is about 37 minutes total with 5 darks. Piggyback on AG8/Orion Atlas EQ-G with PHD2 guiding.

Nice break from planet season !

Very nice, indeed. Makes me want to try my old Takumars of 200, 400 and 500mm lenses.

Good to know. I purchased the same lens awhile back and haven't had a chance to use it. Great pic.

Thanks....I also have the 200mm f/4 Super Takumar....still looking for that big 500mm ebay bargain. These prime lenses focus a little bit shorter in Ha, but stay pretty good right to the edge of the APS sized sensor.

The 500mm would be great, but they’re expensive.
