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.
More than a year has passed since the construction of the Low Spec spectrograph in version 2.0 provided by the author of the project (@Paul Gerlach).
The project provided for the purchase of a ready-made module for illumination of the slit.
From the beginning, I missed a decent calibration module and slit illumination.
But why buy something for almost PLN 100, when you can illuminate the slit while building a spectrum calibration module and add additional functionality.
Everything is great on the "project":
Inside the device:
But the electrical diagram I drew was not correct (I don't know anything about it at the time).
Not everything worked, so the modifications during soldering and compromises started: D, after a few attempts with soldering and desoldering, my calibration module finally works as it should.
It was important for me that the calibration standard should be stationary (not moving), and this of the available components on the market only provides an imaging flip mirror with a tilting mirror.
It is sold under various brands with T2 threads, so it has a lot of possibilities for mounting various accessories and I made the right module for it.
No store in Poland undertook to order it, so I had to buy it on my own (UK).
RELCO 480 starter spectral lamp:
The cylindrical mirror is a piece of aluminum foil stuck to it for packing sandwiches
Slit illumination also works:
Finally, only one LED informing that the slit illumination is on (the RELCO lamp with the diode on doesn't work).
Now it's time to put together the set:
Low Spec with 2 cameras and a calibration module is very big and heavy:
Solar line tests in diffused light on clouds:
RELCO 480 spectral lines have two values, the upper one is measured by calibrating the spectrum with solar lines, and the lower value is taken from
Richard Walker, CH-Rifferswil, 2017, Glow Starter RELCO SC480 Atlas of Emission Lines, available online: https://www.ursusmajor.ch/downloads/sques-relco-sc480-calibration-lines-5.0.pdf
The difference between my measurements and the data from the Echelle spectrograph from the above atlas is basically negligible, everywhere smaller than 0.2 Å, which means that on my scale it is below 1 pixel.
It seems that the construction of the calibration module was successful.
The calibration module will facilitate a sufficiently accurate calibration of the spectra of faint stars without clear metal spectral lines and in regions where there are no atmospheric oxygen and water absorption lines used for accurate spectral calibration.
I had to capture pictures quickly because I have a drift on the diffraction grating holder (the spectra move over time).
Rather, it is loose, there is a micrometer screw and a spring, so the holder isn't very stable.
I would to improve it next.
Made a new video, this is a Astro Systeme Austria specific video, which has direct driven servo motors.
To get them to perform perfectly and be able to track unguided, you have to tune theese motors.
I made a quick video of how the three different methods is working in the "Autoslew" software to run theese mounts.
Maybe this method of tuning mount motors is related to other brands which has direct driven mounts?

So just today i got my new EQ3 mount and tripod delivered.
Brought it out, balanced it leveled it etc etc.
So i polar aligned it, and selected 2 Star Alignment.
1st star to align to: Betelgeuse.
As soon as i hit confirm align the motors kick in but as soon as the mount starts to rotate the motors stop and the hand controller resets itself immediatly and starts initializing all over again.
I discovered that moving Ra on its own works just fine as does moving Dec on its own but whenever i press for example the left and Up arrows at the same time the mount stops and the hand controller resets.
Could this just be a problem with power draw? The Synpro box takes 12V DC and is supplied by a 12V DC car outlet type power source. However i changed this to a 3 Pin UK 12V 1A DC & AC plug.
Im hoping the power supply is the issue and not something else.
