Summary
[edit]DescriptionRho ophiuchi with two pentax 135s (50139076811).jpg |
The rho ophiuchi molecular cloud complex in scorpius. captured 30x70" with my new pentax super-takumar 135 last night hoping to compare it to the images produced by my pentax-k 135. unforunately my mount died before I could get a full hour in on the target so I decided to combine this data with data I captured back in May. The verdict is that the Takkumar is slightly sharper and better corrected for chromatic abberation, but it comes at the cost of less light gathered and coma in the corners. I will likely use both lenses going forward, perhaps this could be the birth of a dual imaging setup down the road. canon rebel sl1, skywatcher star adventure 30x70" pentax super-takumar 135/3.5 @ f/~4.5 captured 7-21-20 14x90" pentax-k 135/2.5 @ f/3.6 captured 5-13-20 |
