Session Notes

Leonid Meteor     M33 - Spiral Galaxy ("Pinwheel Galaxy")     NGC 100 - Spiral Galaxy     Photometric Monitoring - Variables   None     Astrometric Monitoring - Nearby Stars   None

- Early morning session (1.5 hrs duration). Clear skies, but poor seeing & wind - Session operated under semi-automated control, with remote monitoring from indoors computer.   - Main aim of the session were to continue testing dual scope/dual camera operation with autoguiding - 12" LX200 + ST-10XME for imaging - TS 80mm APO + ZWO ASI178MC for guiding - POTH Hub - PHD2 Guiding - Semi/Full Automated Operation  (integrated imaging & guiding using CCDApp2 & PHD2) - Secondary aim was to test VB2015 version of CCDApp2 and test bug fixes /changes in VB2010 version - Ambient Temperature:  1 - 3 degC (minimum) - Notes from 2017-11-17 >>

 Leonid Meteor

Leonid Meteor - 2017-11-17 04:16hUT (Image taken with Oculus All Sky Camera)

Annotated All Sky Camera Image (50%, cropped) See picture for details on time/exposure [ Alt Image ]

Leonid Meteor - Detail The approximate radiant for the Leonids is shown by a white cross (X) The meteor is consistent with this radiant and confirms the meteor as a leonid

All Sky Camera Image (100%, cropped) Image Details as above

Meteor - Confirmation Difference Images (frame - frame before) are used to confirm that the object is a meteor rather than a flash from an Iridium satellite. The former will show no black trace in the event image itself and no white traces in the difference images before/after the event, whilst a satellite will show at least some trace leading-in and/or leading-out of the main event,
