Re: I think I am finally getting better focus on my Orion shot

Kevin Rea <reakevinscott@...>
 

I restacked them using a different stacking program..looks like I still had some star movement.
then I just remembered, I forgot to rebalance my equitorial mount after I put on the dslr..
so, I think that is why the images are stretched.

Re: I think I am finally getting better focus on my Orion shot

 

Kevin,
 
Not really, just that they will have astro-specific optimizations that will be generally helpful.  This ends up being very much a question of what fits best to the individual.
 
Try a search around CloudyNights and see what seems good to you, and don't expect that to be a once-and-done choice.  As you learn, things will change.  There are free trials, so no need to agonize on a decision before trying one.  I'd just pick one and give it a shot.  They'll all be good at slightly different things, and will have somewhat different approaches and different levels of documentation and support.  
 
I started with StarTools, have done a couple of Astro Pixel Processor trials and am currently studying to get ready for a Pixinsight trial.  PI does have a fairly brutal learning curve and I will not start that trial until I think I'm ready.

Hi Robert,
do you have any recommendations for an "astro-image-processing program" ??

Re: I think I am finally getting better focus on my Orion shot

 

Kevin,
 
I'm not in high desert, I'm in low soggy - and I have guide graph envy :-)
 
Very nice, and yes, if I zoom on your nebula for focus, the structure's looking pretty crisp - but I can't see stars in your image, so not sure on that score.
 
You might have an easier time w/processing after stacking, if you used a dedicated astro-image-processing program and saved the Photoshop for touchups.  CloudyNights has lots of discussions on those - a search might help you.

Re: Automatic Meridian Flip (re: APT) #ASCOM #astrophotography

Jay Sanchez
 

Slowly narrowing things down - so far, pretty much ruled out any issues with ASCOM and PMC 8 driver. POTH ASCOM manually flips and slews/parks correctly.
I loose that manual flip control though when either APT or NINA is active even with the software showing the mount isn't connected (to the software), slewing still works normally. Unfortunately, I have to wait to test out manual flips with APT or NINA because it involves an exposure and plate solve (cloudy skies until Saturday). Also, gonna test to see if ASCOM PAD maybe the culprit and test to see if PHD2's meridian flip calibration tool (which I've never used) can help sort things out.

I'll get this figured out!

PHD2 and PMC-8/EXOS II

Jeff Snell
 

Morning all,
So last evening, after a couple of successful nights of great PHD2 interface with the PMC Eight and the EXOSII mount, when I "Push(ed) Here Dummy" the app seemed to be taking an abnormal amount of time to calibrate on the auto selected star, and every attempt at calibration/guiding failed with the following (paraphrased) message from PHD2:  "Ra did not move the selected star enough."  I ran the app multiple times, shut down all apps completely and restarted, shut down the computer and restarted everything, and went through all the PHD2 tools and menus settings to see if there was anything I could adjust or had accidentally changed.  After about six or seven attempts (always with the same result), I quit using PHD2 and just did some short exposure photography work.

Any issues that anyone is aware of that would cause this?  I'm all ears.

More info:  Nights are currently crystal clear, Orion guide scope is in great focus (I could clearly see the star cluster I was shooting through the guide scope), the selected star was NOT a hot pixel, and I am interfaced directly to the laptop from the Orion Starshoot camera through PHD (no direct connect to the mount).

Thanks in advance for any help.

Re: Mount moves off Target

Steve Lang
 

Hey there.

Currently have version "ES6B09T12" - from I have researched that suggests I have version 9T12 installed, and the latest version is 9T15/9T16. Do you recall any further detail?

I have updated in the past (wanted to 'benefit' from the higher current, even though none of my problems were related to that ;-) ) so I guess it's time to upgrade again.

Cheers -

More than once, and last time I stopped it (which was handy) but it's happened b4. Very odd and would be very annoying if it was more common.

Yeah, thought I did - went for the 1,300mA firmware as well when I last upgraded. Will check again tonight.

Thanks for the suggestion.

Re: Mount moves off Target

Steve Lang
 

Hey.

I have noticed something similar a few (maybe 3-4) times. I have not been able to reproduce and I do not know what specifically caused it. It may not be the same problem as yours, but I will describe it here.

I use the G11 PMC-8 for astrophotography only and use NINA for capture and control, with PHD2 for tracking, both via. POTH. When I have seen it, it seems to track at something like twice the normal speed. It keeps going and keeps going. The only way I can stop it (and I only found this the last time) was to hit the 'stop' button on NINA scope control screen. This seems to make it reset to normal sidereal tracking.

I had not determined whether or not it was a NINA error, PMC-8 error or something else - I just don't know. I've seen the same thing enough times for it to be annoying, but have no further details, nor logs. I was going to turn on ascom debugging/trace or something so if it popped up again, I might have some useful logs.

Interestingly, I was going to run the Ascom conformance tool next time to check general conformance, but this seemed to be very much an edge case problem for me.


Cheers -

Hi Robert,

I assume you are using the Explore Stars application when this occurs. The way Explore Stars works in POINT mode is that it is continuously sending commands to move to the calculated position based on the RADEC coordinates of the object adjusted for the mount model set during the alignment routines. If the mount loses communications with the tablet, it should track at the last set rate which should be very close to the sidereal tracking rate. When you manually position the mount using the direction buttons, it goes into TRACK mode where the rate is fixed at the Sidereal rate. I am at a loss to understand why the PMC-Eight would stop tracking completely, perhaps it is not.

I assumed that when you said the mount moves off target that it had stopped tracking completely. How fast does the mount move off the target when this happens?  Have you seen this behavior (loss of tracking) when in TRACK mode? 

The only other thing it could be, and this may be the case, is that if the PMC-Eight loses communications completely with the tablet, after 20 seconds the mount will stop moving. This behavior is designed into the mount system. You can install a version of the firmware that we have available on our website that disables this function and allows the mount to keep tracking when not connected to the tablet. When the tablet reconnects, it will update the information on the tablet and continue to operate.

Here's Leo's Triplet shot on the evening of Leap Day 2020.

What a difference when shooting at a Bortle 4 versus my home location Bortle 8-9. EZ PZ to process comparatively and much less gradients to remove, almost none since the target was near Zenith most of the time.This is a crop from the original frame. Little guys in my wide field scope, but still thrilled by it. Stacked and processed in PI, 1st time completely pre/post processing in PI. And 1st time using PHD2's drift alignment tool versus Sharpcap (I didn't have a clear view of NCP). I normally takes me ~5min at my Bortle 8 home to get excellent alignment via Sharpcap, this time it took me well over an hour because I was completely new to using PHD's tool.

Hi Jay, remember that if you do a plate solve and a SYNC, that the motor counts will update to the new coordinates. If the plate solve is incorrect, then it could cause  large shift in the park position. Remember to always validate the plate solve and check to see if the solved plate scale, focal length, and position seems reasonable before SYNCing the mount to the coordinates.
