Announcement: New Applications
We are excited to announce the launch of our new applications! We're opening up early access to our new applications for searching, downloading, and submitting photometric observations. You can now access these applications through these links:
We ask for your feedback in order to help us improve these applications. Please send feedback for the applications above to feedback@aavso.org. Note: please avoid duplicating submissions across the two submit applications.
OC61 does indeed have a Shelyak eShel spectrograph. We haven't advertised it much because the limiting magnitude is quite bright at the current time. Because of the long focal length of OC61, the star image profile overfills the science fiber, and we don't get much flux into the spectrograph. A focal reducer has been ordered from Optec and when installed, we should be able to go much fainter.
Right now, I'd say the effective limiting magnitude is about 5th. If you have objects that are this bright or brighter, and are interested in using the system, contact me and I'll get you set up.
