Hi! I purchased a Raspberry pi 4 4gb not so long ago with the intention of running a NAS and some other stuff on it. I have since then considered the possibility of using it to control the alt/az position of a mount like the Skywatcher AZ GTi with a python script running on the raspberry pi. I haven't purchased the mount yet since I'd like to hear if it would be possible.
A little more information on my main objective:
Weather satellites and radio has recently caught my attention and I'm therefor considering to mount a directional antenna on the skywatcher AZ GTi mount which then tracks a chosen satellite across the sky. The raspberry pi would be running a program that would send the alt/az coordinates to the mount. I have thought about sending the alt/az coordinates through a TCP socket but I'm not sure how I would connect (and if it's possible) the mount to the raspberry pi or the opposite way.
Here's a video of the current software I'm working on:
I've seen people control mounts like the Celestron nexstar ones but it would be ideal to make the small and light weight AZ GTi perform the same job. If you have any experience with the AZ GTi mount and raspberry pi I would highly appreciate your advice:)
Thank you in advance!
Can confirm my second project with the lattepanda has been a success. 😁 Chuffed to bits,
Flashed my az gti to the az/eq firmware
Installed,, CdC, Ascom, eqmod onto my Windows 10 laptop. Plugged az gti eq mod cable from FLO into laptop and azgti, configured to cdc and eqmod,, azgti now controlled via cdc..
Disconnected the laptop,, plugged the lattepanda in its place,, had to reconfigure comm port,, working via lattepanda now,,
Last bit of the project,, install tight vnc on laptop,, put in panda ip address,,
Laptop,, lattepanda are connected to my smartphone hot-spot.
I now have wireless remote desktop control of the panda,, eq gti / eq panda is born,, 😁
since i started work on my observatory there hasn't been much time for AP, but since lunar photography is done in minutes i had a go yesterday.
SW AZGTI with the Skymax127 and Sony A6300 and Baader Neodymium Moon & skyglow filter.
100 frames taken and 50% used to stack in autostackerd.
I need my garage back so am selling my excess mounts.
1. EQ5 motorised on both axis.
No tripod this was mounted ony pier. Tracks well.
£100 Collect only because of weight .
2. An older type Skywatcher AZ goto mount that came with my SkyMax 127. Good condition .
£100 Collect please but might be able to send if you arrange courier.
SOLDto Pitbull ...thanks
3. AZ GTi goto in excellent condition . Still have the box so can send at cost.
The pic shows it with a telescope on it which is not included.
Location just north of Newark on A1
Thanks for looking
mods VB please move
I'm new to astronomy, I got my first telescope in November (StarMax 90mm f/13), I was really happy with the view of the moon and double stars, but disappointed I could see but barely make out nebula (initially the ring nebula). I also tried to take a photo of the moon with my phone but trying to get a stable shot was too difficult, even with a basic smartphone adapter.
I did a bit of research, found about about Video Astronomy/Electronically Assisted Astronomy (EAA) and decided I needed a better mount and took the opportunity to get a faster telescope (StarTravel 102 f5/). I really like the Sky-Watcher -102 AZ GTe with the ZWO ASI 224MC. I've only used it for 4 nights as there is so much cloud about but it's allowed me to take images of things my eyeball wouldn't see. Although my setup is below the minimum specification most would consider for imaging and entry level for visual observations I think I've found a setup that seems to work for me. I like that with SharpCap I can get instant results and the day after when it's back to cloudy I can get a bit more out of the images with Deep Sky Stacker and Gimp. I have tried looking through the eyepiece at the Pleiades, that was a pleasure as well. I can see how observing with a big Dobsonian and amazing eyepieces would be great, but many objects seem better with a camera than eyeballs. The Horsehead nebula wasn't found until astrophotography came into being.
The photo above was taken on my first night with the setup. The January 2019 issue of Sky at Night Magazine has a review of the Sky-Watcher StarTravel-102 AZ GTe and they give it 4.5 / 5. Combining it with an Explore Scientific UHC filter seems to reduce most of the chromatic aberration and increases contrast relative to the stars, and light pollution.
Video Astronomy/EAA seems to offer a great window into both the visual and imaging worlds of astronomy. As First Light Optics say "Your first telescope is arguably the most important because if the views do not amaze and delight, your interest in astronomy will crash and burn on the runway!" I understand cost could be an issue, but if the beginner had a suitable camera Video Astronomy could be as accessible as a Go-To visual setup, and seems more likely to amaze (especially in the skies of a typical house).
My question is why is video astronomy not the first suggestion for beginners interested in both visual and imaging?
