Thinking of getting the Asiair pro whenever they come back into stock but wondered about the voltage output for dslr, it states that it’s12v but would that not need to be stepped down to 7.5v for dslr.
im wondering if the Pegasus power box micro with Stellarmate might be a better option as the dedicated power box is controllable.
I tried Ekos a couple of years back and had nothing but problems but tried again last night and was amazed at how slick it was, best guiding and first time plate-solvingwas effortless.
I have the original zwo 120mm so reluctant to get a new one unless I have too. Has anybody been using the new advanced or micro power boxes either stellarmate?
I bought two new dew heaters. They are sold to be used on camera lenses and powered from USB. I have modified them to reduce the power from 8 Watt to 2 Watt which will be enough for my demand.
Some photos and documentation from this project:
This will be battery operated and I try to reduce the power consumtion of the equipment.
Hi all, just getting straight to the point.
Just got a Rasp Pi 400 (equivalent to Pi4-4GB), and looking to get into guiding through this as it's obviously a popular (and successful) technique.
Plan is to have the RPi as mini computer at home, running it with RaspPiOS (supplied on µSD with the full kit), then use it with a SECOND micro SD card for astro - I figure having another SD to run Astroberry (as on SGL) may ignore any issues with the family using the pi for other stuff in the house, giving a stand-alone 'computer' as the OS and files would be available on different SD's.
From this point, I'd setup as follows:
Connect the RPi directly via USB to the mount (it's the newer SW-AZ-EQ6Pro with the USB-B port on the mount)
Guidescope (240mm f/4) with T7C (equivalent to ZWO Mini) again USB-B direct to RPi
Nikon DSLR (either on telescope or using camera lenses) connected to RPi via Nikon USB (using the 3 USB points on the RPi-400) to control capture and later using this for plate-solving (but that's not for just right now!)
I don't spy any flaws in the plan, it's just going to be a matter of testing and setting things up hoping to follow the guide for Astroberry as linked to SGL below...
Or is there an alternative OS? From brief reading, Astroberry includes KStars & PHD2 which is what I've got for use on the macbook (although not used in earnest as it doesn't appear to like the cold too much!)
What about guiding software - I know KStars comes with it's own, and can run PHD2 from within, with PHD2 being the industry standard (and simplest?) to use?
Control will then be sitting in the warm via OS-X, which seems to be again a common technique as I've had posts on my other questions about this!
I've been contemplating making a portable power box so I can take my mount to a dark site, a friend gave me an old lorry battery that no longer turns the engine over but will hold some charge. My intention was to get a nice enclosure and build something that looked professional like a few other members have created on here, unfortunately spare time is limited so I went for a simpler solution and created the following and it works very well.
I've been trying out astrophotography from home, where 220V socket is available with unlimited power.
I want to be taking my setup to the field next year, but I'm wondering how to power all the devices.
The mount (10micron GM1000) needs 24V@3A (peak 4A). To get 24V@3A I need 12V@6A DSLR that can run from batteries, and I have lots of spare batteries on standby Raspberry Pi to control the devices, 5V@3A, equivalent to 12V@1.25A Dew Heater that I've just got, but never used, needs 12V@1A I'm considering some upgrades in the near future:
An autofocuser, 12V. Power requirements should be minimal. Replace DSLR with a cooled camera, 12V. I don't know what I'll get, but top models need 3A. Don't know how much of it is used by cooling, and how much is used by the sensor. Questions:
Is it safe to power the mount from a DC hub? My mount's manual says "Please don’t use unregulated power supplies because the output voltage of these units is not good enough to operate the mount.". I didn't find anything that says the warranty is void if not using the pre-approved power supplies. If I don't want to power the mount from the DC hub, how can I power the mount and the DC hub from the same battery? I saw these funny devices on Aliexpress but don't know if they are any good: https://www.aliexpress.com/item/32911966417.html What kind of batteries do you use to provide multiple Amperes to all the equipment all night long? Mount needs 6A (at 12V), cooled CMOS camera needs 3A, dew heater needs 1A, Pi needs 1.25A. That's 11.25A at 12V, which is 135W of power. The battery must be huge. I saw discussions of various DC hubs here:
