Slightly Smaller FOV, Larger Setup, Comet 13P/ Olbers Stills has Some Show Left, Aug 07, 2024.  
 
Moved up to the C14 Hyperstar in conjunction with a full frames sensor still hosting a FOV of  ~ 2d 44'  x 1d 49' (Formally the RASA 11 w FFrame was ~ 3d 15'  x 2d 9' ).  The RASA setup seemed to be losing some of comet Olber's post perihelion splendor so I changed out equipment.  I have lost some resolution due to the short cool down time for the 14" scope and early evening imaging time, so details may be lost here.
 
 
 
The comet is still showing considerable activity with the Plasma tail in the "low" position in relationship to the comet core.  Mind you, I have maintained the camera angle at approximately the same 0 degree angle since early June for all setups.  This means that tail positioning in the frames are solely due to comet activity and orbital change over time.  Will we see a ion tail switch upwards shortly?  (precursory view of yet, unfinished/unprocessed view of last night's data say - not yet.)
 
 
 
The moon sets before most of my comet imaging of 13P is finished tonight and with a little managing of tomorrow night's subframe duration (shortening) I should get away with tomorrow night's also.  Moon is indeed entering the scene (Thx Chris) and this comet will slip away into my mind's obscura.
