Alain,

 

I assume you used the “Load” button to load the Horizon file?

 

And, did you click “OK” to close the dialog window after loading the new file? If so, what makes you think it is not using the new file?

It looks like someone bought that 155 EDF yesterday. If the buyer happens to be a member of this forum, we would all would be interested to hear what they have to say about it once they take possession of it.

Dale,

A fair question. Yes, I do have a keypad. Yes, it is in EXT mode. The mount was without question initialized from APCC. Plus, I did indeed check the time and offset on the keypad. They are correct and match my PC clock. I'm not sure that it matters so long as you're in EXT mode and init from APCC, but the site info on the keypad also matches the site info in APCC.
Ah yes, good. EXT mode on the keypad means that you are likely initializing the mount from your PC, and I presume it's good on its clock.

In case you missed it, kudos for the A-P Tools plugin for N.I.N.A! Works great! I also appreciate the time and effort you put into the documentation on your website. Very helpful, thank you.
You're welcome! I'm really happy to hear when people find it useful. The Tools plugin got a minor update yesterday so be sure to update if you also update to Beta 20 of NINA 2.0.

Hi Alain,

i'l using Horizon feature and, for this, i've used the excellent apps (https://rkinnett.github.io/gyrocam/) from R.

and after modifying the header (#AP...) the model loads well but if i reloaded another *.hzr ... Horizon keeps
the olds values ...... How can we do a reset please ?
What makes you think it is not working? Can you post screen shots?

Re: Power supply question - Powerwerx SPS-30DM

ap@CaptivePhotons.com
 

Just thought I would do a brief update.

Powerwerx said I can RMA it, but also said they had no ideas on the technical front.  I have lots of time so holding that in reserve. 

Ran one night on one supply, two nights swapped, no events.  Well, maybe... 

Last night at 3:39am I got the "wake up its raining" alert from my rain detector (Hydreon RG-11).  It wasn't.  Checking the security video this morning I didn't see anything other than me staggering out there to look at it (it was nice and dry).  Could be a moth or something (these are optical).  Could perhaps be a power glitch?  That's the first ever false alarm by the way.

Here's the bizarre part - this is within a minute of the time when the power event happened the last time (can't get more precise as the rain event takes a bit of time to propagate through two MQTT servers and alert through Home Assistant). 

It is not similar to the first event a week or so earlier.  But.. .within a minute.

There were no apparent computer issues this time, nothing rebooted, it kept imaging; I checked the images around that time and nothing unusual, security video showed no signs of UFO's.  So this may not even be a power issue.  The moth is a viable possibility (it's IR video and far away so very likely I could not see a moth on the security video). 

But ... eerily similar time of day. 

I've got a lot of energy monitoring stuff, and both internal UPS's and panel monitoring showed no voltage glitch (but they probably will not see anything fast).

Now wondering more if the utility company has some kind of scheduled power maintenance around this time.

Murphy creates coincidences just to screw with our head, I realize.  But it is enough to make me start questioning the idea it is the supply, and instead it is some kind of transient, probably from utility maintenance that happens on a schedule.  Maybe.

But a (home) UPS won't help these, if that is the case, as my home UPS is not seeing anything.  Home UPS's generally run on utility power unless they detect an event, as opposed to a continual dual conversion.  I could get a linear supply with their big filters to ride them out better.  I could lug 100# of batteries out each night (I have them charged and ready that's just not an attractive routine task). 

Or... Murphy was just screwing with me and it is a coincidence.

Sigh... it's the "conservation of problems" principle, I got a mount I do not have to worry about, so the worry moves around.

Sorry I wasn't more clear about this, but it just happens that windows update is another SPF that will cause an unintended reboot on your PC. Your PS/UPS won't prevent it, so even though it may not be the root cause for your problem, it is something you will want to attend to. And it won't cost a penny.

Twice, I've unknowingly and accidentally disconnected the extension cord from the 110VAC outlet by kicking the extension cord from the outlet and the PWRgate quickly switched to battery power and I never lost a single sub thanks to the PWRgate. My battery was a Walmart deep cycle lead-acid battery and easily survived the whole night powering everything. The battery costs less than $100.

Phil60,

 

The SGPro coordinates in your screenshot are J2000. This is different from the mount’s coordinate system, which is local apparent, which some people call JNow. This is not a problem but if you are interested you can find more details if you do a web search for “J2000 vs JNow”.

Hello again

In SGP, once I have  unparked the mount ,the Current telescope's position displayed from the Software does not match  the reading of RA/DEC from the ASCOM driver, especially in Longitude?  Is it normal behavior ?
Does it affect the pointing accuracy of the mount or should I take an image, run a plate solving and resync the mount to get the exact coordinates?  

Thank you in advance for your advices

Re: Power supply question - Powerwerx SPS-30DM

Eric Weiner
 

Excellent.  Thanks for the detailed info Jeff.  40-50% usage is respectable at your loading.  You bring up a good point regarding multi-night usage without the need to charge.  I'm on the front range in Colorado.  The only thing stopping me from a Yeti has been the cold weather.  I've considered the cooler idea, but would like to hear from someone with Yeti experience in cold weather before dropping that kind of cash.  I use a lot of Li-ion batteries in my line of work, and they can loose a significant amount of charge under 0 C, and they don't work under -20 C (nor will they charge).  My 2x 12V lead-acid AGM setup in a pelican case (70Ah total) works great for my needs, although I do bring a Honda EU2200i with me for recharging and coffee.  I've got a small 25A charger which allows me to re-charge both batteries in parallel in less than 3 hours using the generator.  In cold weather (-5 C) they are about 20% less efficient.  Above 5 C I don't notice a difference.  LifePO4 are an attractive option (although wicked expensive), but have the same cold weather concerns as typical Li-ion.

Again, thanks for the detailed response.  Much appreciated.

Re: Strain wave gear PEC limitations

Christopher Erickson
 

Besides my 1100, Mach1 and soon to be 1600 (which I all love,) I also have an RST-135E (which I also love) and I have ordered the ZWO AS5 directly from their web site. They charged me immediately and are saying shipments will start in April. I dissected and documented my first RST-135 in macro pics and I'll do the same for the AS5.

My past experience with ZWO tells me to say to hold off getting excited about the AS5 until I have studied it extensively internally and under the stars.

Re: Power supply question - Powerwerx SPS-30DM

Jeffc
 

Eric…. Here’s a few reasons I went for the Yeti1500x…

First tho, I want to mention:  At the time of the 1500x purchase I was considering building a LiFePO4 based supply but there were some logistical and component supply issues going that route; the 1500x was a choice in balancing weight with capacity, and also availability (REI stocks the GoalZero gear.)

1) Space.   While I have a collection of optima yellow tops (AGM), these take up space in the vehicle and are heavy to load/unload/move.  With recent vehicle changes here , using the yellow tops became a showstopper.   

2) Capacity - Sometimes i go out for multiple nights and would prefer to over-provision.  One time I was out and underestimated the power consumption and was hurting for power. (I think the weather was colder than normal, and I switched to a new camera drawing more power.)   It turns I could only reliably get 1 night out of the YellowTops.  And on top of that I would need to charge them during the day.. which meant bringing multiple AGM chargers for multi-night trips (when there’s a generator or nearby daytime charging.)

3) Regulated 12v.   The Optimas worked great but were not regulated.   I fried two 12v “auto” laptop adapters (replaced under warranty) as a result of the voltage dropping below something 11.5 volts. 

4) I’m in the SFBayArea .. so it’s not super cold here, but I’ve had the 1500x out in near freezing weather (for a couple hours) at remote sites and did not notice any issues.  I have the 1500x in a soft case which has some insulation, so that might help with the cold.  I doubt I’ll be using the 1500x at -4F (or even below 32F much), but if I did I would just put it in a cooler.
(Fwiw, I have noticed cold weather issues with the YellowTops.)

5) Turnkey… at the time I wasn’t in the position to build a DIY power setup (too many projects) and was looking for a turnkey solution with quick charge capability (the 1500x charges in about 3 hours with the 600w charger.)

5) Regarding capacity - I use an 85w computer (desktop class, not laptop), camera and a couple dew heaters in addition to the mount.  The camera probably averages about 3amps with peaks at 5amps.  With the YellowTops I would designate one battery for running the dew heaters, and also separate the camera, mount, and computer on their own batteries.  I would monitor the battery voltage through the night — a bit annoying.   All this hassle is gone with the 1500x.   And with multiple flavors of ports I can also use the 1500x for daytime charging a laptop and cellphone. 
One night uses about 40-50% of the 1500x capacity.  If I’m conservative I figure I can get two nights out off the 1500x, but usually I just charge it during the day with the 600w charger. 
The 1500x also does double duty as a power supply for the occasional Bay Area power failures.

Re: Power supply question - Powerwerx SPS-30DM

About $2k for the batteries, inverter and 200w solar charger. You can use one 100Ah battery and a smaller inverter as that would handily operate 2 rigs. I'm sure someone will say just run it off the battery, but my thoughts on this is that the battery is 12.8v, by the time that sees each device its low 12's. The 'benefit of the up/down efficiency loss' is that you don't need the batteries close to your rigs. Batteries stay in the truck and use a 100' 12Ga extension and then locally convert to 14vdc. Even if you're spread out, just run another extension cord to a local power supply so you aren't running long 12v power cords.

While this 'up then down' conversion is certainly not the most efficient, I have run 3 rigs, a laptop and kept iPads charged all night with room to run the coffee maker in the morning before recharging with solar and a small Honda generator. 

The batteries are maybe 25lbs/each and the inverter is maybe 10lbs.
