Re: RA Mesh adjustment for 2104 model Mach 1 GTO

That one is no better. Unfortunately it is cross contaminated. The RA should show the PE and the Dec should show only drift with no PE. It appears that the calibration is off by 45 degrees.

It may not even be calibrated at the celestial equator, so it's not going to be accurate for RA.

The previous run was unguided data

There were significant number of failed calibration attempts

Not sure what's going on with the previous graph and so many difficulties with calibration. It may be that you have a cable or connection loose somewhere

Hello Mr. Christen.

Firstly I want to express my sincere gratitude for offering to evaluate my Phd2 log data in light of how busy you must already be.   I am not convinced that any issues are not operational efficiency, for example, I likely could improve on my guide-scope/ guide cam structure to make it more solid. On the saddle was a 152mm F8 refractor triplet with a few LBS of imaging related equipment.

Attached is Phd2 log from last night. @ 23:48 I began a recalibration, then I proceeded with the guide assist on after having skewed from the handbox from Park 3 to NGC 7541.

Re: RA Mesh adjustment for 2104 model Mach 1 GTO

Yep, it looks like the guide cam was rotated since the previous calibration run and prior to running the second GA session you posted the screencap of.


Re: RA Mesh adjustment for 2104 model Mach 1 GTO

 

it's possible though this run reported no prior calibration issues - the calibration data prior to this wasn't in this guidelog. It looks like maybe the guidescope slipped and/or was rotated

when the calibrations are successful they look spot on, but many are

Re: Smart Meridian Flip with NINA #APCC

Andrew J
 

Hi Joe.

I also gave N.I.N.A a go this weekend. I didn't have meridian flip issues, but I did have problems getting my dome and safety monitors working. After it shut down everything the second time because a cloud went over I quit and went back to SGP. I haven't been able to determine how to build a sequence with auto-recovery. I think N.I.N.A is good sotware with a LOT of potential, but stilll a little rough around the edges as one would expect as version 1.11 is still in development. I love that I can use the Ground Station plugin with MQTT to publish the state of each piece of equipment. I use it with home assistant to keep tabs on everything. MQTT opens up a whole new world as now I can control non-ASCOM switches and other things in my observatory using MQTT and Home Assistant. That said, for N.I.N.A to be come my primary imaging software I would need the ability to easily Pause sequences, Replay parts of sequence, and it desperately needs a "debugger" that would allow me to place break points and step through the sequence one step and exit a sequence if I discover a problem. I also need to figure out to auto-recover a sequence so I don't loose an entire nights imaging if a few clouds blows over and sets off my safety monitor.

Re: Fine tuning PHD2 settings for 1100 with Encoders #Guiding

Roland Christen
 

I still don't see a screen shot of the RA and Dec unguided tracking graph, so I really cannot explain to you how the results of that graph will show you what is happening. It is the key to setting the Min Move for any given night, which is really the most important setting. You want to set MinMove such that the guider loop does not chase random sky motion due to seeing. The numbers below give a clue but they cannot get you to understand the why. That is what I wanted to be able to convey to you and others who may be watching this newsgroup.

Please post a short 2 - 3 minute guide graph taken with 1 second guide exposures and corrections turned off. The easiest way to turn corrections off is to set MinMove to 20.0 for both axes. No need to do a GA or other fancy tests.

Why is it that people don't want to do this simple test? It's not hard and takes literally just minutes, but reveals everything you need to know. And i will explain it all in an annotated visual once I get your graph.

This is really helpful!! You are right, as a software developer I keep thinking this is just an equation that needs to be solved and all I need is the right inputs. No doubt there is some "artistry" involved. That said, I do want to at least understand what the 'theoretical" settings should be and use those as my starting point.

I think in large part I am just getting hung up on the terminology. If I look at this output from PHD2 Guiding Assistant, are you saying that my P-P Arc Seconds is the Declination, Peak of 0.73 px (1.44 arc sec)? If yes, how does this help me determine what MinMo I should use as a starting point? I took this screen shot before I hit the finish button, but it came back and recomended a RA MinMo = 0.20 and a DEC MinMo = 0.30. 



As mentioned in a previous post, I did another imaging run on Saturday night and all I changed was the aggression on both axis to 0.63 or RA and 0.72 for DEC and my graph fattened out quite a bit. I was able to achive an RMS of 0.23 on one point during the night. I think by relaxing the Aggression it alllowed the encoders to "do their work".

I have been imaging from a permant setup for about 6 years now (previously with a Mach1) and guiding has always been my achillies heel. I get it close enough to get round stars, but have to admit I really don't understand it. Now that I have a mount that can track extreamly accurately, I want to make sure I am using it to its full potential. 

FYI. In case it helps. In addition to the 1100GTO mount, I am also using a  Tele-Vue NP101is. I bought this scope specifically for the 1100's "shack down cruise". I wanted a short scope to give me plenty of room for error around the Pier until I get APCC, SGP, etc. fine tuned. My primay scope is a TEC 140, but I am not putting on until I get everything working together and able I am able to have several all night imaging runs without issue. For guiding, I am use the Baader Vario Finder 10x60 along with AP's bracket to help reduce flexure. Primary camera is an ATIK 16200 and guide cam is a ZWO ASI178MM.

Re: Smart Meridian Flip with NINA #APCC

Ray Gralak
 

Joe,

I think you want to leave meridian limits enabled, but only enable West counterweight-up slews. Dale may need to confirm that.

I mentioned in an earlier post that high West-side pointing terms are likely caused by there not any data points at widely separated declinations. The Eastside doesn't usually have this problem because the first point at the zenith can provide one widely separated dec sample.

Are there any particular parameters in the Meridian tab I should be cautious about? I've always kept the

Re: APPM and ASTAP #APCC

Ray Gralak
 

Bill,

There was talk about this last week on this forum, so you may want to look back on those posts. The short answer is that APPM uses ASTAP's "automatic mode" for calculating the view/image scale field during a regular APPM run with the expectation that ASTAP will accurately calculate image scale. However, ASTAP's automatic mode is not very automatic.

So, you may have to configure the ASTAP's settings in APPM to get ASTAP to solve images. I am working on a fix to get around ASTAP's unexpected behavior, but it is not ready.

In the longer term, I am considering porting just ASTAP's plate solving logic to C#/.NET so that I can make plate solving work in a way that is most efficient for future APPM features.

At the end of an APPM run, APPM will automatically enable pointing and tracking rate correction when it loads the new data into APCC, so you will need to turn it off afterward.

Subject: Re: [ap-gto] Smart Meridian Flip with NINA #APCC

OK, thanks. I've actually starting making Dec models with three rows of points but I had this one already
made so I used it. Ironically I looked at it just before starting the mapping and debated whether to update it
with another row. Go figure.

I thought I had disabled the pointing model when I unchecked the "Enable Pointing Correction" box in the
"Pointing Model" tab of APCC. The program still shows it as unchecked as it was before I started the run. Is
there somewhere else I need to disable the feature?

APPM and ASTAP #APCC

I have APCC 1.9.0.11 and latest ASTAP. When I try to run a pointing model the ASTAP solve always fails. If I leave the scope at the run target location and press the Plate Solve button, the solve is always  successful in a few seconds. What am I missing?

Re: Mach2 with TEC180 for visual

It will bounce around when you bump it lightly. I would recommend a 1600 mount if you want stability at high powers. I have my 175 on a 1600 mount and it's just about perfect for that scope.

Roland,

Yes i know the 180 has a huge moment arm. When you say boingy is it during slews (which I can reduce) or in general due to the long moment arm?
