I replaced the original HEQ5 tripod with my diy aluminum stand. It allows an easier horizontal adjustment, a better orientation to the north and carries all accessories. The second image shows my Raspi setup with my diy raspy housing (quick and dirty!) carrying beside the raspy also a waveshare motor HAT board which is driven by Kevin Ross' driver and a temperature controlled fan . The focuser is driven by a NEMA 14 stepper motor. The 2nd image also shows my diy dewheater. I am planning to make it temperature controlled soon. The whole rig is powered by a 12V/6A power supply attached to the stand.
AZ-GTi with various bits of home-brew
* 3d-printed bracket to hold the raspberry pi and power supply, air duct for cooling fan, GPS holder, box for homebrew 12V UPS
* counterweight bar and tripod
* aluminum rail for the guide scope shoe
* external antenna mod for raspberry pi
* eqmod cable
* 12V power harness with XT30 connectors
One of my SetUps.
- This one with TS EDPH II 61/274mm (incl. Flattener)
- on EQ6R-PRO
- OMEGON veTEC533c with Optonlong L-eNhance or IDAS LPS-D3 filter
- SVBONY 165 with ASI120MM-Mini
- RPi4 Astroberry with external SSD
- additional Router (Repeater) TP-Link
- GPS on one leg
- 230V to 12V Box
- TS Triplet APO 80/f6 with 0.8 Flattener/Reducer
- ZWO ASI533 MC Pro
- ZWO ASI 120MM Mini for tracking
- ZWO EAF Focuser
- Dew cap heaters for APO and guidescope
- Dell Optiplex with UbuntuServer 22.04 LTS & Indiserver
- Remote-operated by KStars & Ekos installed on a notebook and a Desktop-PC
- Image Processing with PixInsight
The telescope is on a mobile platform and parked in the house between observing sessions.
Attached is also my first completely processed Ekos - astro image (Comet C2022 E3 ZTF), cropped and downscaled.
Some settings here are really awesome !
In comparison, mine is much more modest :
- carbon tripod given for 20 kg load
- equatorial mount from e-bay
- customised Star-adventurer classic
- laser pointer (fine previously when using SLR, nearly quite useless with cam)
- Nikon lenses (here the Nikkor Reflex 500mm f/
- RPi4B 8 / 256 GB / SM OS
- homemade 10000 mA battery for the RPi
- 4xUSB hub
- 5000 mA battery for the hub
- newly bought ZWO ASI183MC classic - I better have stayed with my SLR !
The PI, batteries and hub are assembled with velcro and attached to the mount with velcro too.
I am now in search of a USB to SSD adapter in the style of the one in attachment, that could allow me to get rid of the SD card and could be attached to the hub.
I admit I dont know which criterions have t be taken into account.
I recently got my very mobile setup up and running:
It's a William Optics Star71 (5 element flat field apo) with a 294MC pro mounted on a iOptron HEM15 and controlled by stellarmate on a Raspberry pi4.
I have two filters with this setup to choose from:
- Antlia ALP-T duo narrowband
- IDAS LPS filter for RGB imaging.
I made the carbon fiber guidescope myself (it's -very- lightweight!)
And also the focuser & controller. (Direct drive, usb powered)
The dew heater is adjusted by a simple pwm motor controller.
I use a powertank out in this field. For travel, I'm using 100 Wh powerbanks that output 12 V (power delivery).
