2012年9月16日, ε-180ED, QHY8 CCD, 300s x 9, EM200赤道儀, Off-axis guider + Superstar + PHD自動追蹤, 大氣透明度: 5/10, 氣温約21度, 濕度約76%, 攝於西貢.
昨晚出來試新guide cam, 總算work.
請問: StarlightXpress Superstar的敏感程度和QHY5如何比?
Just the built-in UV/IR filter window was used.LT 寫:Can it be Nebulosity (FITS input) ==> Nebulosity (TIFF output) ==> PS (resized and Jpeg output).
It doesn't matter to have some colour lost. I just want to see what the noise level is and the Red casting in a 10 min or 5 min RAW.
Another question, any filter (LPS, CLS, V4 or IR) used with your QHY8?
Thanks.
This is the first light of my attempt under the sky, and it is too early to give detail comment.LT 寫:Master Subaru,
That is a very excellent shot in considering the so poor sky conditions in HK.
What's your comment on your new CCD?
