What's the best software to do solar tracking and imaging on a Raspberry Pi (Astroberry)?
I have been learning how to use Kstars/Ekos/INDI and it's working pretty well at night, but since now the nights are super short and the sun is more "exposed" I'm also trying to do solar imaging.
Astroberry oacapture, but how can I control the mount to perform solar tracking? Normaly I use EKOS for this, but then I can't use it with solar film capture.
Please let me know which software you use to connect the mount, focuser and camera (QHY-II-5L-C). It's ok to control the mount and focuser in a separate software, but using two separate INDI sessions seems to crash it. Advice and recommendations are welcome!
Thanks & Clear skies!
Managed to get some solar observing in this week, trying to get back into it after quite a break. Having been away some time I'm definitely out of practice., so I'm trying to record my amateur attempts and publicly shame myself on YouTube so I can learn from them as I go along.
Also need a tracking mount, its hard trying to do manually and focus at the same time. I'm in absolute awe of some of the stuff you lot produce, absolutely fantastic. This footage was from Wednesday 15th April 2020, very different compared to April 2014.
Solar Minimum v Maximum comparison
Made a solar finder out of a spare skywatcher finder-scope using the pinhole camera principle.
Removed lenses, covered front with foil and added a pinhole with a needle. Held in place With elastic bands (could use something more permanent but this is very easy to replace). The lens cap still fits over the foil for protection when not in use.
On the rear I used some kitchen parchment taped to the inside of the adapter that holds the “eyepiece stalk” and added a crosshair.
Pinhole projection gives a solar disk about 3-4mm and whole thing is adjustable as per the normal finder-scope.
Tested yesterday and works a treat, I can now get the Quark on target without having to use the WL wedge with 25mm then 8mm to get it aligned first.
I am wondering if anyone has a suggestion that might help me
My imaging set up is an RC reflector with an FLI proline 16803 camera and 50mm Astrodon filters (LRGB + 5nm narrow band)
I have had a string of issues...everything from my mount had mechanical problems to my telescope had issues with the mirror cell to some family distractions...but at long last I seem to have everything working with the exception of the Astrodon Ha filter.
Attached are representative 30minute subframes of the horse head and Pacman nebulae in Ha, SII, and OIII. I get similar results with different objects although for bright, broad spectrum targets like M42, I will get data from the Ha filter (much as the stars shine thru on the HH and Pacman) although even that data does not comport with other imager’s Ha images of those objects. The LRGB performance appears to be normal. My hypothesis is that this Ha filter is defective, perhaps not centered on 656.3nm
I have contacted Astrodon and exchanged a couple of emails with Cary Chleborad seeking some help. At first he claimed there was no issue because with enough manipulation some data could be extracted from the Ha. Later, when confronted with the other narrowband frames and the obvious difference to the Ha, at first he ghosted me, but when I said I would ask other imagers for help, he responded with a new position stating that because of the way the filters are made and their robust quality processes, it is impossible for the filter to be defective and therefore something else must be at issue. He does not offer a suggestion of what might be the problem, nor is he interested in having me send the filter back for evaluation. Frankly, I’m more than disappointed given the premium I paid for Astrodon filters
All that aside, and taking Cary’s position at face value, does anyone have an idea of what might cause this behavior other than the filter? In a perfect world, does anyone live in the Austin, Texas area who would be willing to try my filter one night and see what they get with their equipment?
The attached link is to the raw, uncalibrated files right off the camera. I think a simple blink process in PixInsight will show what I’m talking about.
I’m a little at my wits end, please help!
