Re: UPDATED FIRMWARE NOW AVAILABLE #ExploreScientific #FIRMWARE

 

Jerry,

Thanks for the offer and confirmation! I probably should stick with GA firmware, though.  Yes, the numbers I mentioned were just tracking, not slewing.  Very odd - I remember the earlier bump up, and I think I even did a bit of testing on one you were trying. 

Anyway, if all is as intended, then I'll just roll with it and figure out how to augment my power. 

Out of curiosity, though... did the amperage range I found look reasonable to you, considering the power consumption of the PMC8 itself, PLUS the steppers?

- Bob

Hi Bob, thanks for the feedback.  For the EXOS 2 I changed the current from 600 mA (tracking and slewing) in 9T10/11 to 700 mA (tracking and slewing) in 9T13/15 and then in 9T17 to 600 mA (tracking) and 900 mA (slewing). I have confirmed these numbers in the firmware code.

If you are mostly tracking then the motor current should be the same as you saw in version 9T10/11.  I can send you a custom firmware with only 600 mA if you like to compare. I increased the motor current during slew so that it would overcome more inertial load and also overcome a little more imbalance. Let me know what you would like to do.

IEXOS 100 dovetail and DSLR #iEXOS-100 #alignment

Stade
 
Edited

Hoping someone may have a similar setup as mine and could enlighten me?  I am currently learning the IEXOS 100 mount, using only a DSLR and red dot sight, no polar finder, no telescope and the polar tunnel is not much help.  Software I'm running (and learning), NINA, CDC, and astap.  I'm all set up with via serial and getting more comfortable by the night.  I'm thinking of getting a ZWO 120mm mini guide camera with a 50mm orion mini scope to mount on the dovetail beside my dslr to assist with polar alignment using Sharpcap, guiding (eventually) and eliminate the current red dot scope.  Currently during daylight, I will align my dslr, red dot sight and the iexos 100 tunnel all on something in the distance. How would I confirm that the guide scope is in sync with the polar tunnel, or mount since it's the mount that has to be polar aligned?
Thanks for any insight.
Meghan

Re: UPDATED FIRMWARE NOW AVAILABLE #ExploreScientific #FIRMWARE

 

Jerry,
 
I've been out twice now, after upgrading to your latest firmware release.  My previous was fairly old, circa v13, probably.  Yes, I should have noted it.  :-(  
 
Anyway, 9T_17 is good news, bad news for me.  The good news is that AT is now centering my target for me with just two exposures, where before it could take as much as six. Two thumbs up on the pointing fix.  
 
The not-so-good news is that I may need to re-think my battery power, because power consumption has definitely gone up, to the point where I will probably need to increase supply for winter use.  (No, Wes, I do not want to lug a lead-acid battery :-).
 
You mentioned that you had increased slew current...are you sure that you didn't increase tracking current as well?
 
My power consumption measurement is a bit indirect - it's through my Pocket Powerbox's management app, which gives me instantaneous voltage-in and amps consumed from my Cel Pro LiFePO4 battery.  If I strip off the cameras and heaters (which consume surprisingly little power!), my minimum config is the P-box, USB hub, and PMC8+motors.  So yes, there's extra load in there from both the hub and whatever overhead the p-box imposes.
 
Stripped down like that, the p-box's app reports total amps consumed as varying between 0.9 and 1.4A low/high, with most readings in the 1.0 to 1.2 range.  It flickers back and forth quite actively. My recollection is that back in the day, 0.8 to 1.2 might be low/high, with most around 1.0A +-1.  
 
It's enough to shorten my useful imaging window (staying above ~11.4 volts-in) by about an hour in summer (but still ok) and probably put me in trouble for winter, even with keeping the battery warm (and I do).
 
So... basically just asking you to confirm that power consumption defined in firmware for both tracking and slewing really is as intended, and a heads up for you on possible battery run time impacts. 
 
Thx!
 
- Bob

Thank you for explaining the heavy east and camera heavy balancing.  For some reason I have had trouble getting my head wrapped around that concept.  However, your explanation made it apparent.

You may recall that at one point I posted that I was getting five minute subs with my Exos 2 using an RC6.  Balance and proper guide scope were the key.  Well I have returned to a modified version of that, but have not yet repeated those results.  This made me start thinking about how I can better balance things and improve the performance of my setup.

Your guide provides the information I need to deep dive into making the necessary improvements.

I really appreciate your work and sharing it with us.  Thank you.

Jeff and Fermin,

In the left window pane there is a selectable "Subscription" icon just under the "Home" icon that will allow you to manage what e-mail your receive. I also was bombarded with e-mails but looked for and found where to control that. As for finding your past posts, I have not experienced that issue. By using the search tool I can even find posts from months ago.

As for "Discourse", I am assuming you mean Discord, one of the groups I am in uses Discord and I do not find it any easier than IO, but that is what the owners selected so that is what I use.

82+ hours!, that's dedication for you.  Excellent result Wade. in a 9 sky as well

I guess those 3nm  filters can suck up a lot of exposure time.
The iEXOS-100 mount had an easy time with that little cat on top no doubt.

Were you tempted to process an image after you took say 20 hours worth?.
I would be interested to see that and compare to this version.
