NGC 7380, Flying Horse / Wizard Nebula, Hα, 12 Sep 2014

Conditions excellent again. Chose this target because I already have RGB data from this season at the same scale, so I intend to do HαRGB combination. Had a terrible time getting CdC+PicGoto to work correctly. Tried synching both from Delta and Zeta Cephei, and from both the synch seemed to work but as soon as I hit goto the telescope reticle in CdC would jump way off (in RA). Finally tried from Beta Cas, going the opposite direction in RA, and everything worked. After doing a meridian flip, the synch from Delta Cephei worked fine. Once again my session hung about 40 min. after I went to bed. I've searched both Windows and VMWare logs and so far haven't figured out what is going wrong. I suspect a bad VMWare setting. I do get a Windows error about being unable to find a sound device each time this happens.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
