I'm afraid this will be yet another DIY all sky camera build! 😂 Hopefully interesting though... While developing my all sky software (shameless plug, see signature) one of the biggest problems is that I don't actually have a permanent all sky camera setup myself. I live in the middle of a big city with massive light pollution where the summer temperatures are just creeping up to 40C+, not ideal... So for a while I have been thinking about setting up a remote all sky camera to help with the testing of the AllSkEye app. Initially the idea was to mount it at a relatives house but then once I looked into what would be required to make it fully remote controllable I was thinking that if I go to all that trouble, I might as well look for a location with great weather and dark skies.
After a few inquiries I got a really great response from Jose at the E-Eye remote hosting facility in Spain. This was fantastic news because not only will the camera have nice weather and dark skies but the facility also has fibre broadband which is almost a must for what I have in mind further down the road (I am also planning to transfer some image data to cloud storage for archiving and further processing and that could potentially be a lot of data). So this is where it is going to go (all being well and my 3D printer not packing up!
I'll try to follow my progress here, maybe it will be helpful for someone. The basic idea is pretty simple:
Setup a completely autonomous and remotely controllable all sky camera Sounds easy enough... Well, let me tell you, it is not! To anyone having setup your own remotely hosted scope setup, my hat off to you, it's not an easy task! Initially I split this project into two parts:
The camera, lens, housing and everything that goes with it The control box that will control the above Unfortunately I don't have time just now to go into any details but will hopefully be able to do so soon. I just though if I don't start this thread soon I never will 😀. The state of play at the moment is that the control box is pretty complete and the camera housing is nearing completion (3D printer is very busy, not a fast manufacturing process unfortunately).
Here are a few pictures of what it looks like at the moment:
I have an EQ5 telescope mount which i use for astrophotography. I have modified it with a motorised RA axis using a bipolar stepper motor - my thread for the build is here .
I want to expand the mount's tracking ability by motorising the DEC axis and using a guide scope/camera. I generally use the mount in fairly remote locations so would like to use a raspberry Pi for portability.
I understand that I'll need to use a Raspberry Pi Camera Module for the guide camera.
The capability I want is:
1. guide the mount along RA and DEC axes using a guide star as feedback
2. track the mount using the RA axis only, and if possible continuously take 20-30 second exposures on the guide camera (this functionality is optional, but would assist in polar alignment of the mount)
I don't want any GOTO capability. I am very new to RPi and need some help:
- do I need to write code for this, or is there existing programming available for what I want to do?
- is it possible to avoid the use of screens (in the field)? My preferred option would be to flick a switch to start and stop the guiding, with another switch for alignment mode (or something simple like this).
- do I need to use any particular stepper motors/drivers for raspberry Pi? I'm using a bipolar stepper motor running quarter steps, with an A4988 stepper driver
- is the RPi 3 Model B+ the unit I should buy?
Starting my 1st IOT project. Since i've been an astrophotographer with no permanent setup, it makes sense to reduce the physical footprint (and the weight) of as many equipment as possible, as well as to do better cable management. I am soon going to start using Astroberry Pi server, an Ubuntu based suite for Astrophotography. Just purchased a Raspberry Pi 3B along with a 3.5" display for that. Lets see how it goes.
£130 Ono ! Will calculate postage when sale agreed but I can't see it being more than £10 with royal mail
Stellarmate imaging astrophotography computer.
Based on raspberry pi . Comes with upgraded 32gb card rather than the standard 16gb. Included in box is hdmi cable and usb cable with power switch.
This was an early Christmas present but is turning into a project I just don't have the time for. Works with anything that has an indi driver.
It's like the zwo ASI air ...but can be used with other equipment including zwo.
Please note if you have Altair cameras the driver is still in development.
