If you look at the the images on your computer, the sun will be larger in the frame of one than in the other. You acknowledged that when you said "only the D750 would have more field of view around it"Ī 24mp image from a D750 has the same number of pixels as a 24mp image from a D7100. You are correct that the number of pixels and size of the sensor don't matter regarding the size of the image of the sun that is projected on the sensor (which I agreed with in my comment above "Lens X will put the same sized image on the sensor") but the output file that you get (i.e., the JPG or RAW file) will have a larger sun on it.
I understood what you meant, but apparently I wasn't clear in my previous comment. I do not appreciate your condescending last two sentences. I'm sorry, those are the simple laws of physics.īut don't feel bad, many people don't understand this. The number of pixels, and the size of the sensor do not matter.
The Sun will not "be larger in my final file." The size of the Sun formed at the image plane is dependent only on the focal length of the scope/lens. The image file will be larger, but that does not make the size of the Sun larger. You will get more pixel density, and that might or might not give you more detail depending on the quality of your optical system, whether you have image blur due to mirror flop, shutter shock, tripod instability, wind, polar alignment error during long exposures and the limit of resolution due to seeing and diffraction. Megapixels, pixel density, and sensor size have nothing to do with the size of the Sun at the image plane. So while you're correct that "Lens X" will put the same sized image on the sensor, the higher pixel density of the cropped sensor camera, means you'll get a larger, more detailed image file with it. Both the D600 & D5600 are 24mp cameras, but with the cropped sensor cameras, the sun will be larger in my final file. I'll be renting two D5600's and a couple of long zooms (Nikkor 200-500 & Sigma 150-600). I agree with you in general, however.(You knew that was coming, right? ) I own a D600. If you shot at the same focal length with your D750 and you D7100, the Sun will be exactly the same size in the images, only the D750 would have more field of view around it. This is something that is widely misunderstood and maybe even intentionally fostered by the camera companies. The size of the image of the Sun is determined by the focal length only. Cropping does not extend the focal length.
It depends on whether you want to try to get close ups of things like the chromosphere and any prominences, or if you want to go wider and get a lot of corona. Very good, but I wasn't trying to convince you to switch. Partial phases are not that big of a deal at a total eclipse anyway. At this point, I'm all tested with the Baader and don't intend to switch. Perhaps their new and improved film compares more favorably to the Badder than the older black polymer?ĭon't know, haven't tried it. " Images through this new SolarLite film are optically superior compared to the images from the older Thousand Oaks black polymer film." I guess half as sharp for half the price.įrom, "About Thousand Oak's SolarLite Solar Film" I've tested the Thousand Oaks version and it is not nearly as sharp as the Baader.
Or buy the Thousand Oaks version for half the price, (at least right now) You'll finally get to utilize those scissors and scotchtape skills you learned in kindergarten. It's really simple, I've made a half-dozen of them.

Instructions on how to do this are included.ĭo I need to buy separate frame/holder, or is that included in the pkg? You make a simple holder for the specific size you need for your specific lens. The highest optical quality that you can get in an ND5 solar filter is the Baader AstroSolar Film.
