Chimera 2, a new high-speed and wide-field imager for Palomar achieved first light! Gregg Hallinan is the PI, I’m proud to have performed the lens-design for this instrument, all optics are off-the-shelf, so the real challenge was the imaginative way in which the off-the-shelf optics were combined.
I’m attending the TMT Science forum in Tucson next week! This will be a great opportunity to talk about my work on TMT! Follow us on #tmtsf14.
I’m attending the SPIE astronomical instrumentation meeting in Montreal (from June 22 – 28). This is a great time to get together with colleagues from TMT, and discuss SED Machine.
Based on Japanese Patent J2001, 253050, A, I constructed an approximate optical model for the Canon EF f/2.0L 200-mm lens. I can’t know for sure if this model matches the constructed hardware, but the model is a good starting point.

Below is a beautiful integral-field spectrum of Saturn!
Thanks Avishay Gal-Yam et al. for a shout out to SED Machine in their recent Nature paper “A Wolf–Rayet-like progenitor of SN 2013cu from spectral observations of a stellar wind“. They even go so far as to simulate what the SED Machine spectrum of a 2013cu-like event will look like:
I’m attending The transient universe as seen by iPTF and ZTF meeting in Stockholm Sweden. Discussion will range from circumstellar interaction, cosmology, and asteroid science to details about the iPTF, and ZTF surveys. I’m keen to learn about all anticipated used of SED Machine!
The SED Machine delivered its first public classifications. The instrument team (Nick, Robert, and Sagi) had a beautiful four night run in early May. A student and postdoc from the National Central University in Taiwan were also there to watch SED Machine operations. On the nights of 3 and 4 May 2014 we posted Atel #6113 and Atel #6114. Atel 6114 was particularly sweet as the classification was generated within 20 minutes of the complete exposure.
The SED Machine camera (120-mm f/5.5) operates over a pretty broad wavelength range (360 nm — 1000 nm) and delivers absolutely beautiful images.
It’s a Petzval-like lens with an external (real) pupil about one camera focal length in front. The designed images were achieved (as can be seen from this mercury-lamp spectrum:
