How is Roman's field of view 100 times bigger than Hubble's?! #shorts [댓글]

[ytcid:Ugyu7VohCDgqpJ5YgJF4AaABAg] Ironically, Hubble’s total field of view is greater than Roman’s WideField Instrument. The catch is Hubble is based on a two-mirror Ritchie-Chrétien optical design which corrects for spherical, coma, and astigmatism, but cannot correct for field curvature. The prime focal plane is picked off by five separate instruments, plus three outlying fine guidance instruments. The entire focal plane spans over 1° field of view. But each instrument has a tiny field of view which is relayed to their individual sensors where the limited field curvature (and Hubble’s residual spherical aberration error) are corrected as needed. Roman uses a Three Mirror Anastigmat optical design, which allows for a large, flat corrected image plane at prime focus — the perfect place to have 18 sensors covering the equivalent of a ~0.8° x 0.4° field of view! ???

[ytcid:UgxJw1HtLOSqoSQy-6V4AaABAg] Thanks Dr Becky ، a few weeks ago، i got a link to send my name to this telescope by another astronomy facebook community page۔I wonder what would be the purpose of sending our names۔Does anybody have an idea۔Thanks

[ytcid:UgxGQHDnoCytPjlviGN4AaABAg] Just be be precise: the Hubble cameras were replaced during STS-125 in May of 2009. However, they were supposed to fly in 2005, so Hubbles cameras were designed more than thirty years ago.

[ytcid:UgwtkeVwkrBrpWCD7r54AaABAg] It’s not the size that matters… it’s just your field of view that needs to change… I’m 100% trying that next time

[ytcid:Ugy2oKDZJK5ogbYrQkl4AaABAg] I can't wait for the first images!! I'm so excited! I am curious though. Since the Roman telescope was designed, how far has optics and cameras advanced? I know it takes a long time to go from drawing board to mock up and then full build, let alone waiting for funding, so time has passed. I was wondering how much our tech has advanced since inception?

[ytcid:Ugy2aj7P7IEYv7AN8md4AaABAg] I don't get it. Isn't it a bad thing to have a large field of view? If you have the same number of pixels, that means the image will be a lot more blurry. Why not then just get a GoPro360 style lens and take one image of the entire sky?

[ytcid:UgxT04Xhm-gSM9ZH8Dl4AaABAg] Hopefully there's enough money to operate it later... This and NEO surveyor are basically the two next big space telescopes I'm waiting for, sadly no new stuff for IR, X ray and gamma...

[ytcid:UgzmZLaGrhCC0aqU4D54AaABAg] Surely this is but the top line item? I've sent a dozen vehicles to the scrap yard since the final camera upgrade. 4 had cassette decks! The step change that is coming is probably not hyped enough.

[ytcid:UgxJDGQC67LcnF4x1pR4AaABAg] I don't understand how the same mirror can collect more data at the same resolution and dimness just because of the camera. Do the Hubble cameras only record a tiny percent of the available information coming from the mirror? ALSO--and I realize the degree to which images overlap may influence this--but in one place you say the Roman can do 100 times what the Hubble does, in another 12 times (17 months vs 17 years) and in another 1,200 times (one month vs 100 years) and I don't understand that, either.

[ytcid:UgyAOG9VsdzBXtdsZu54AaABAg] Well I just hope they grind this mirror with the right curvature BEFORE sending into space. I wonder if Perkin-Elmer still contracts with NASA. ....
