Description

On 1-19-2022 I did my second run with the ASIAir, shooing the Rosette Nebula.  I had hoped to either find a variable star or two or maybe an asteroid, but that was a fail.  Part of the problem was that I got complacent and after starting the imaging I plopped down on the couch and set about relaxing.  After about 40 minutes I thought I'd check the progress on the phone display only to find that the imaging run had stopped after only three images due to "image failure."  With basically 40 minutes of potential integration time lost, I started the run again, this time with  120s exposures instead of 180s exposures.  After putting the phone on a table that placed it nearer to the scope outside, I started the imaging.  I watched it for about 20 images, everything was nominal, so I plopped on the couch again, this time orienting the phone so I could see the display.  Complacency struck again -- I stopped taking looks and at about 30 images, "image failure" stopped that run, which I didn't catch for about twenty minutes.  Now having lost even more integration time opportunity, I put the phone directly on a window sill to get it even closer to the scope (the phone is 5G and while there are a number of advantages to 5G, the phone needs to be relatively close to the controller).  From then on I watched it like a hawk and I got in a full run (proverb: a watched pot never boils; astroproverb:  a watched ASIAir controller never fails LOL). I report all of this for the benefit of imagers who are just starting out -- like me -- with the ASIAir controller.  The breaks in the data collection messed up looking for variable stars with Muniwin and the 120s exposures weren't deep enough to catch asteroids or there were none in the field.  Anyway, I managed to get a decent image of the Rosette with 120 minutes of integration time and a little aesthetic cropping.
