2019 July 8 UT – (38628) Huya

Event Details

Huya is a binary TNO in a resonant orbit with Neptune. This event involves a bright star (mag 12.7) but the star will be on the southwest horizon and very low, especially for teams up north. For all event details (including sense-up) visit: RECON Event Detail Page for (38628) Huya

Reminders

We wanted to provide the following observational reminders:

  1. Use the altitude (Star alt (deg)) and azimuth (Star az (deg)) of the target star listed for your location on the Event Detail Page when selecting your telescope location to avoid trees, buildings, and topography that might block the star. The target star will be low (between 17-22 degrees for most locations) on the southwest horizon. A fist held at arms length is roughly 10 degrees, so we’re only talking two fists! Due south is azimuth 180 and due west is azimuth 270. The star ranges from 237-247 across the network (so southwest).
  2. Be sure to use the focal reducer with your camera.  This is the 1-1/4″ adapter with glass lenses on either end used to connect the camera to the telescope that increases the field of view of our system. Do NOT use the adapter that does not have glass at either end, as this does not provide any focal reduction making it extremely difficult to find the starfield.
  3.  Be sure to set your IOTA-VTI on FULLSCREEN mode.
  4.  Remember to save your data files with 20190708_  prefix in a folder labeled 20190708.  See Observation Protocol below.

We remind observers with the QHY174M/C camera to follow the QHY174M/C camera setup.

  3. Print this page as well as the Event Detail Page above and practice finding field prior to event.
  4. Be sure to practice on the target star field prior to the event!

Feel free to contact the RECON leadership team anytime by emailing tnorecon-org@mailman.boulder.swri.edu.
