This image was taken on 17 march 2005 using a grism on an st 8xme nabg imager through a tak fsq 106n at f 5. the image has been frequency calibrated and corrected for instrumental response using vspec software. Image details:this image is a single 1 minute integration using a grism spectrograph at newtonian focus on the cn 212. maximdl was used to take the image and process the data. My first project with the grism was to make a "good" stellar spectrograph. it took a few weeks, but the results were very pleasing. the grism star spectrograph produces a spectrum which is in line with the telescope's optical axis.

In the present work, we consider an optical design of a slitless spectrograph for an existing 0.5 m class telescope. this design concept has a number of advantages such as compact size, simplicity,. In this study, we analyze over 800 h α emitters identified from the complete nircam grism redshift survey (congress) in the goods n field. The design and modeling efforts presented have helped overcome the many challenges in designing, implementing, testing, and calibrating the rst grism and prism optical instruments. While the grism data measures the full (spatially resolved) emission line without flux loss (in principle), the nirspec line flux measurements need to be corrected for slit losses.
