Hi toursin, welcome to this forum.
best value for money?
It is a difficult question .
The camera and lens you suggested are not sold in Japan, so I don't know their performance at all .
From their catalog, there is no big difference between YV27X29LR4D-SA2L and YV27X29LR4D-SA2.
It seems that it is the export model or refined model.
Therefore it is worth to test. If its image quality and image circle size is almost equal to
YV27X29LR4D-SA2, then it may be the best value for money.
But about the KPC350BH, there is big difference in catalog.
1. CCD is 1/3 inch. --- may loss 40% of lights
2. Gamma 0.45 --- it decrease the contrast of night sky a lot, compared with gamma 1.0.
3. No AGC limiter --- it may decrease S/N a lot.
... may be the number of meteors in one night will be one quarter or so.
Though the value for money depends on the observation purpose, I don't recommend this camera for night sky observation. |
