Re: Full Frame Focus Exposure Time By Filter
Iver, Thanks. I did use those settings which worked just fine. I did run into a number of problems though, not related to the GOTO connection. Initially I couldn’t get a good image from the guide camera, all I got was a black image with no data. I disconnected/reconnected the guide camera a few tim...

Re: Full Frame Focus Exposure Time By Filter
All, I’m really liking AA8, especially when moving along the learning curve quickly! I ran into another dilemma and looking for a solution. I have an 8 position filter wheel with LRGB and narrow band filters. When auto-focusing I’ve been using 3 seconds exposures for the LRGB filters and 30 seconds...

NGC 5466
This is an integration of 8 x 1200sec ( 2.66 hours) exposures using an Orion Starshoot Pro V2 OSC 6MP APSC camera and a 10in F10 SCT @ F7 via a Starizona .63X SCT focal reducer. I autoguided the image with an OAG using Astroart's Full Frame guiding. PreProcessing: Sigma Sum Colour Demosaic = 4 gradi...

M13 - Feb 27
This is an integration of 43 x 300sec ( 3.6 hours) exposures using an Orion Starshoot Pro V2 OSC 6MP APSC camera and a 10in F6.3 SCT @ F5 via a Starizona .75X SCT focal reducer. I guided the image with a 50mm F3.6 guidescope using Astroart's Full Frame guiding as I couldn't find a suitable guidestar...

Re: Nova Sgr 2023
Awesome!
So you're using an 85mm camera lens on an equatorial mount?

M64
This is M64 from last night: 10in F7 SCT on a CEM120 mount, 8 x 20min subs, dark subtracted, Drizzle stacked, 20 x LR deconvolution, DDP and a gradient filter in lieu of flats. I'm not completely happy with this image as we had some high, thin cloud, and I didn't get enough subs. M64_8x20minLRx20_DD...

Re: how to automate darks
Which camera are you using?sharky1961 wrote: ↑10 Feb 2023, 07:43Good Morning,
can somebody help me to automate my darks library.
for example how can I automate 50 darks with temperature -10°c and 300 seconds?
where can I see the actual temperature of the sensor.
best regards
Rob

Re: Vanderbei Deconvolution for coma and field curvature.
That's interesting. Yes, that plug-in is single-threaded. It looks like most of the blurring is caused by image deformations from different wavelengths, not PSF. Maybe after having separated the image into R-G-B channel the new alignment with distortions could attenuate the problem (align R to G, t...
