Re: avi look strange
Sorry to break in. I have the same issue with a avi, recorded recently with a ZWO ASI 1600 MM Pro. This is what the avi looks like in a avi player: M13-avi.jpg This is how the stack looks like in AA7, it has been shifted to the left: M13-avi-AA7-stack.JPG The avi is recorded with SharpCap, it can be...

Re: Ambient temperature in FITS header?
Thanks Fabio. It’s still not in stock, so I haven’t gotten it yet, I’ll try asking ZWO.

Re: Ambient temperature in FITS header?
If the ZWO EAF sends temperature over ASCOM, I suppose it will be AOCAMBT:
See https://diffractionlimited.com/help/max ... itions.htm
Code: Select all
AOCAMBT – ASCOM Observatory Conditions – Ambient temperature in degrees C

Ambient temperature in FITS header?
I see that the sensor temperature from my ZWO ASI 1600 MM Pro is stored along in the fits header. If I have an ambient temperature sonsor, will it be possible to store this value in fits header as well? I have ordered a ZWO EAF ( https://astronomy-imaging-camera.com/product/zwo-eaf ) with a temperat...

Re: Autofocusing in the sequencer
Thanks.
How does AA do the autofocusing? Does it take a picture and look at some stars FWHM, and then try to minimize them taking more pictures (V-curve)?

Re: Autofocusing in the sequencer
Thanks Fabio. I missed that.
So setting focuser position to 99999 in AA7 SP1 means autofocus?
Can’t wait to get a ZWO EAF and try it out!

Autofocusing in the sequencer
ZWO is about to release their auto focuser, ZWO EAF, very soon (I think you can already buy it directly from ZWO). https://astronomy-imaging-camera.com/product/zwo-eaf ZWO-EAF.JPG So I was wondering, is it possible to include auto focusing in the sequencer, for example between each filter shift? As ...

Re: FITS file doubles in size after preprocessing
Ok Fabio. I will use dark flats next time.
I was also recommended doing that for my new camera on a danish Astro site.

Re: FITS file doubles in size after preprocessing
Hi Fabio, I tried using stacking method "Average", but still, the result file is 64 MB and it has BITPIX = 32 !!! If I follow the steps below, the change seems to happen when the picture is saved.

Re: FITS file doubles in size after preprocessing
Thanks for the answer Fabio.
What stacking method would You recommend for a ZWO ASI 1600MM Pro at unity gain or below?
It’s a 12 bit camera.
