MOON.csv – uses the GOTOMOON and MOVEMOONTOREF script commands to take lots of images in all filters. Takes 11 images at a time through B,V,VE1,VE2, and IRCUT filters, then loops back. 100 times.
The present version of GOTOMOON does not put the Moon in the center of the image field. We understand why that is, now: Ingemar Lundström spotted that there is a table-lookup based on ‘nearest previous neighbor’ rather than an actual interpolation. As the table is spaced at 2-minute intervals the Moon will slide from image-edge to image-center at 2-minute intrvals, which is what we see. This will be fixed in a later version of GOTOMOON.
DOMEAZ placed in a script appears to work well – i.e. no crazy round-trips, and works well in the East at azimuths like 75 degrees.
DITHERMOON.csv – takes ‘dithered’ images of the Moon – i.e. Moon moves about in two nested Releaux triangles. All filters. Takes about an hour to go through all filters at all dithered positions.
LOOPING.csv and FFdusk.csv – a pair of scripts that are used to start and do flat-fields at DUSK (i.e. not dawn). LOOPING.csv is started before dusk and takes B-band images on the NAS – the user checks if the exposure level is such that the event has begun. When the level is right (i.e. not saturated and in the 50000s) then a Normal Shutdown is performed, System_Data_Table.csv is edited and FFdusk.csv is placed instead of LOOPING.csv. Then that is started in the MASTER CONTROLLER and that should now run through the dusk event for about 20-30 minutes extending the exposure times in such a way that well-exposed images are obtained all the way until full darkness. Tricky to do due to the ‘bump’ during dusk and also if there are any clouds, watch out.Well, the ‘bump’ is NOT visible here. Typical. But usually there is a ‘bump’ on the dusk part of the bottom curve for illumination (at 6PM). That bump can cause you to make a false start so that later the light is too high and all the images end up over-exposed. The nump lasts about 15-20 minutes. Good example on the dawn shoulder! Might be clouds low on the horizon or whatnot.
ALTAIR.csv, JUPITER.csv and all STARNAME.csv scripts – have the coordinates of the star in the script, so only start these scripts if that object is above the horizon! Loops through all filters with (somewhat) appropriate exposure times.
