I now have a 1200 l/mm gratring, so I decided to give it the firstlight on WR134
This is mostly a test, but I did several things wrong! Among them:
- 5 x 900s = 1h15m (more than 1 hour)
- no spectral calibration
- no flatfield
- no CCD response correction
- no normalization
- no estimation of resolution
- no background subtraction
- Guiding did not go super-well..
But I did use bias and dark images.
C11 + LhiresIII (35um slit) 1200l/mm + ST10XME (==>)-25ºC 2x2
5700 A region.
I am open to all kind of comments... Could this look promising? How should I best tame the hot-pixels, not destroying the information underneath?
Thank you,
