I see. Yes my guide scope is 176mm so that would explain inability to get better than 1”

You really need this PowerBox that I have. Has AC, DC and USB power outlets and will charge off AC or DC, sounds perfect for your solar panel.

There’s all kinds of power conditioning and management in these devices. The only problem I’ve seen is when your power source can’t deliver the watts. Spec voltage levels are nominal and can be varied greatly. The typical AC to USB power adapter will run on any voltage from under 100 for NA to over 200 for Europe.

The problem with a laptop is that it can draw a lot of power when charging. I have to double check what the charger output is.


The power adapter for the MacBook Air is 45W. It’s close, or eep the air off while charging and should be good.

Sounds nice. I only have 128GB and it’s a problem to keep from maxing out on the drive. Most of my files are on a server now. I only have enough space for a couple of evenings of capture and processing.

PK wrote: Thanks! Any thoughts on solar charging the MacBook Air? I operate far from power on weekends, and would need to charge the Macbook Air.


Interesting... I think the laptop recharge would not be an issue but I use a fairly large Eliminator 1600 powerbox (Canadian tire) to power the mount. I recharge at home or by running my car. But recharging takes a really long time because its a trickle charge - less than 1A, but this would be good with a solar panel. It takes the whole day tho. I would say, you would need 2-3 A @12V from a solar panel to recharge and lots of sun!

I recently started using internal guiding to simplify my process. Works well because now I have round stars but I would have to say they are a little soft. I don't think its focus because I focused just before the shot.

How can I tighten up the guiding? I didnt find any settings help in the guide module manual. Maybe it was poor seeing that caused the soft stars?

Stellarmate uses little power, so that seems ideal. What are some ideal ways to control Stellarmate in the field?
Should I just stick with screen sharing on an iPad, connect to a Macbook Air, or just buy an HDMI LCD screen, keyboard and mouse and use only the Stellarmate?
Please share your thoughts and experiences.

I use a MacBook Air. Works great because it will easily run all night on battery. In fact, I can run all weekend on its battery! Its very easy to handle and comfortable to use from the car, and I can bring it outside for the 2 minutes it takes to adjust the polar alignment while I look at the real time image on a big screen. I run Kstars on the Mac with remote connection to stellarmate which runs the drivers - I don't use VNC except to shut stellarmate down at the end of the night.

Thanks. I’m have a rural spot. I think it’s about 3.5 or 4 on Bortle scale.

Last night I tried dithering but after my first image, the clouds rolled in and all I got was one shot. But the internal guider worked like a charm.

I have only two questions that are dictated by the fact that I'm relatively new in the forum and a primer in the use of Kstars.
Does the Mac OS release with your improvements will be distributed in the form of a new Kstars installer? Does the new release will be published in the newsletter or is it already available?


Last I checked, the Mac OS version does not support DSLR's due to USB interface issues so if you have a DSLR in your system, you'll need to drive it with a linux computer. I think many - if not most - use a Raspberry Pi. So these driver updates would be readily available for that. Presently I use a Mac remotely connected to an RPi3(B+) which runs all the drivers. I highly recommend this setup and buying a StellarMate to get a ready built system.

Yeah, this Is great news! I'm really interested in the synscan driver too, so I can go to the scope and still get my hand controller features. Its very useful in the field. Thanks!

kross wrote: The synscan driver is usable, I use it myself. It has limitations, though. Can't use plate solving or syncing within kstars. You must polar align and 2 or 3 star sync from the handset, and not kstars. Recent versions of the synscan firmware have a nice polar alignment routine built into them now..


Yes, I friend has been using it but it never quite zeros in on the PA like Kstars' PA tool.

Good luck with skywatcher!

Have you tried Skywatcher support? Is there anything I can do to help? Do you debug with simulators because I don't get a lot of observing time where I am.
