Hi ...

I am confused about "Apparent Coordinates" and "J2000 Coordinates" being entered into Sequence .... can anybody help to clarify?


Very late last night I was attempting to carry out a series of imaging runs using Sequence in order to eventually make a mosaic of part of the sky.


Because of this I needed to enter the coordinates into the "Target Details" window in Sequence (see attached jpeg) for each separate run.


In preparation for doing this I took several quick images using MaximDL until I had the areas of sky where I needed in my cameras FOV.

I then took the RA & Dec information from the Autoslew screen and I entered these coordinates into the "Target Details " window in Sequence ready for a full set of Sequence runs.


At this point I realised that I was not 100% certain which box on the "Target Details" window in Sequence in order to enter the coordinates from Autoslew :-(


I am attaching two jpegs to show what I am talking about ... hopefully it will make sense!


I can't seem to spot anything to really help me in the various ASA manuals.


Rather than waste my time last night (the temp was falling below zero) so I decided to pack things up until I could find out what was the correct way to enter the coordinates.


Any guidance with this would be very much appreciated.

Cheers Mike

Real is showing in Autoslew. That what you would use if you need Autoslew current position
