Re: Pause PHD2 when FF AF?

Is it possible to make AA8 tell PHD2 to pause AG while AA8 does a Full Frame Auto Focus, FF AF, in a sequence? When using an OAG, PHD2 doesn’t like sudden the large FWHM changes on the guide stars, that occours when doping a FF AF. AA8's full frame, multistar AG is excellent and I find it better th...

Re: Making photometry measurements in AA8 (and do a AAVSO file)

Hello, I've tried to make AAVSO compatible file which I could upload (to AAVSO) of an RR Lyrae type star: https://www.aavso.org/aavso-alert-notice-786 So far no luch with my normal software I use (ASTAP). Haven't used AA much execpt some individual astrometry/photometry measurements with AA7. So ba...

Re: Can't open image stacked with Pix Insight

I just tried to open an image from a friend that was stacked and saved with Pix Insight. This is how it looks and I opened the Fits header. Image stacked with Pix Insight.jpg Has anyone encountered this before? IIRC, PI is not conforming to the FITS standards. Also they use fractional values for pi...

Re: Plate Solving - No Luck

Thanks, Dunmuro. I have had little luck with AA8 controlling the mount or plate solving off-line with no telescope hooked up. Things are just... weird. For instance, it did successfully plate solve for an image of M51 if I told it to look for M51. On the same image if I give the center search regio...

Re: Plate Solving - No Luck

Re: AA8 SP1: In another post I asked about installing a catalog for plate solving. Bill kindly explained how to install GaiaComp, which I did. I not longer get an error message when loading the star atlas. But plate solving nearly never works. I've been banging my head against this for months. I to...

Re: AA8 and UCAC4 cat installation?

Just downloaded AA v8 and currently going through the various set-ups. I've hit a snag in that I can't get UCAC4 and comet.txt into the catalogue folder. I've followed the instructions and have the MPCORB.DAT (which has a .GZ file extension) and Comet.txt downloads. How do I get them into the catal...

Re: Help with image processing

Been getting good results with image processing but having problems with the Cat's Eye Nebula, the surface of the nebula is very dim despite stacking 20 ten minute exposures. Any suggestions for bringing out the colors? Happy to provide a link to the flats, darks, flat darks and all the images. Sta...

Re: Strange behavior with display

Hi I took some images with SharpCap of the sun in Ca light. I processed them with AutoStakkert. A PNG file was produced. When displayed with Microsoft Photo, a nice sharp solar edge can be seen. When I open it same image in Astro Art, I cannot see the edge of the sun. I there any explanation for th...

Re: Binning CMOS ASI2900MC

When I select 2x2 binning is AA8 doing "software binning" for CMOS cameras? I noticed a check box for "Hardware binning" in the ASCOM driver. I am about to go out to my dark site to image some galaxies and I don't want to waste "sky time" trying to figure this out. Thanks in advance. Use hardware b...

Two recent images from the Serpens Observatory

https://photos.app.goo.gl/397RHsTFh4Zj51CbA Jones-Emberson 1 (PK 164+31.1) from Feb 24/25 + 25/26 2022. Taken through a 10in SCT F6.3 OTA @ F5 using a Starizona .75X SCT reducer atop a CEM60. I used an Orion Star Shoot Pro V2 ( APSC 6MP OSC sensor) camera and 31 x 900sec subs for a total integration...
