Thanks Merlin99

I have an AP Mach1 GOTO mount but I am interested in putting the Airmass into the FITS header so it can be read by my photometry software.

Thanks for info Fabio.

Is it possible to get a pre-release SP5?

Is there an Airmass calculation in AA7 or AA6 that can be taken from the ASCOM mounts altitude/azimuth info and be placed in the FITS header?

Thanks
Erik

The problem has been solved using the return value of FindCoordinates:

....
....
nstars = 5
ok = Image.FindCoordinates(ra,de,nstars)
if not ok then continue
....
....

so when the function fails, the script continues to the next object.

Hi, I am trying to automate my telescope to image a list of objects. How can I safely stop imaging a particular object if the object sky is cloudy and move on to the next object? I am using the script function Image.FindCoordinates(ra,de,nstars) If I set a conditional so that if the number of stars ...

This is the response I received from Atik : "What you are seeing is the build up of dark current while the image is in the vertical readout register. At the end of the exposure the image is moved from the photo diode (very low dark current) to the read out register (higher dark current). The first l...

Dunmunro I am imaging in a dark sky to the NCP region. I am seeing this gradient all the time in add and avg images from all sky orientations and cooling to either 0 or -5 deg C. Could it be "amp glow" in the camera? It is a 4 year old ATIK 428EX The telescope is a GSO 250mm RC with a AP reducer. Th...

Yes, I am using flat fields, bias, flat dark and dark frames

Hi,

When I either add or average images in AA6 SP4 I get a noticeable vertical variation in the background.
Why is this happening?

Thanks

Thanks for your response Fabio

I set the AP GOTO Keypad and AP ASCOM V2 driver pulse to 0.25X and 0.5X sideral but the guide star left the guide screen during guide calibration.
I will try your test next clear night.

Telescope control was set to ASCOM
A6 SP4

Hi,

I have a Atik GP attached to a f/3.75 80 mm dia guide scope.
What should I use in the Telescope setup for the Guide? It was set to "Same connection as GOTO"

My main CCD camera is on a f/5.3 RC 10 inch

When I calibrate the guider it moves the guide star out of FOV.

Thanks

Thanks Fabio for suggestions.
