Does this DEC Arc feature just happen naturally in the process of generating a model?

Okay, that's what I understood from what Craig has said previously.

But I think most imagers want longer exposures than 20 seconds. How would this work if a user wants to do 10 minute exposures?
Without an initial correction there might be enough star trailing in a 10-minute image that plate solves would fail and no images
would ever get collected.

I'm interested because APCC has a built-in declination-arc modeling feature. That is, it plate solves along the same declination at
different hour angles and produces a best-fit tracking rate model for each declination it samples. APCC interpolates rates between
individual declination arcs to produce a really accurate tracking rate model throughout the sky and falls back to the regular
all-sky tracking rate model if the user goes out of the area of the sky where there were no declination arcs to rely on. I showed
this feature to a number of people at AIC last November.

Yes, it is possible to have both active at the same time.

Hello,
I had a Mach1 GTOCP4 for 1 year and I used it in my observatory. I happened to use the WIFI connection to do positioning with Skysafari, but I did not if at the same time I had the USB / Serie connection active with the connection on my PC and APPC open.With my new Mach2 and the GTOCP5, I already connected by WIFI with Skysafari, but since with the connection to the PC (during the photo sessions) I noticed that the access point was not active so invisible in the network WIFI whether from PC or smartphone, however it appears when APPC is disconnected from the mount.It seems to me to have understood that the USB / Serie connection could be done by a virtual port. True or false? This allows to connect to the GTOCP5 in another way (except keypad) and therefore can be by WIFI.The question is therefore is it possible to have active at the same time, a USB / Serie connection on the PC and a connection by WIFI on the smartphone?

Thanks

20 seconds isn't really long enough to capture drift unless the seeing is perfect. It takes at least 3 minutes to get a good handle of the drift at any one spot in the sky.

It isn't set on the first image, it sets on the second one, so a short ~20 sec image is made first, then another ~20 sec image is made, and the initial tracking corrections are then applied on the third science image at the normal exposure you decide. Each subsequent exposure is calculated according to the tracking information gained from the previous image, and each one adjusts the motor speed as required to keep within the limits that you configure. Once the initial tracking rate is set, subsequent corrections are fine adjustments made by the software. In order not to chase the seeing conditions, you can configure AT to make adjustments every nth image, as described in the User Guide (which is in abbreviated form at the moment, but more than adequate for our purposes).

So, in a first time setup how is the tracking rate set for the very first image?

Re: Mach2 Unguided testing continues

Ray Gralak
 

It isn't set on the first image, it sets on the second one, so a short ~20 sec image is made first, then another
~20 sec image is made, and the initial tracking corrections are then applied on the third science image at the
normal exposure you decide.
Okay, that's what I understood from what Craig has said previously.

But I think most imagers want longer exposures than 20 seconds. How would this work if a user wants to do 10 minute exposures?
Without an initial correction there might be enough star trailing in a 10-minute image that plate solves would fail and no images
would ever get collected.

I'm interested because APCC has a built-in declination-arc modeling feature. That is, it plate solves along the same declination at
different hour angles and produces a best-fit tracking rate model for each declination it samples. APCC interpolates rates between
individual declination arcs to produce a really accurate tracking rate model throughout the sky and falls back to the regular
all-sky tracking rate model if the user goes out of the area of the sky where there were no declination arcs to rely on. I showed
this feature to a number of people at AIC last November.

the software. In order not to chase the seeing conditions, you can configure AT to make adjustments every nth

Yes, it works at multiple new targets in one night in different parts of the sky. The methodology incorporates a
plate solve of each image and subsequent correction using data from the previous image. It does what it's
supposed to do, easily.
So, in a first time setup how is the tracking rate set for the very first image?

Re: Mach2 Unguided testing continues

Thanks Don, it's easy to use and I've been getting aspect ratios of around 2% to 6% regularly. This is
unprecedented with me. I set it up and go to sleep. Enjoy!
Does that work if you are going to do multiple new targets in one night in different parts of the sky?

I think that type of application may be useful for certain types of telescopes that are hard to model, like some of the larger inexpensive truss tube scopes. If one is using a solid refractor the all-sky model that APCC Pro creates will give excellent results throughout the sky. I've posted images up to 30 minutes unguided at 1.74"/pixel with round stars.

Roland, this looks exciting, any ETA for release?

This seems like a great feature for us mobile (non fixed installation) users. Given how easy and fast
this is, 5 minutes/hour of object tracking, will this be usable if you also have a PC connected (for things like

I use SkyX, but would love to see ASTAP or PS2 become supported.

SGP does not have internal plate solving routine. There are 4 options for plate solving.  All have a learning curve.

Astrometry.net (remote and local) (free)
ASTAP (free)
PinPoint ($150US)(APPM can use PinPoint directly as well)
PlateSolve2 (free)

Just the ability to run APPM was worth SGP's price ($100US)

Mo,

You might be surprised to learn you can use a small guide scope and guider array where it becomes easy to find a guide star. Just say'n.

Thanks for chiming in Brian! I'm sure much of my difficulty comes from using the built-in off-axis guide camera on my ST-4000XCM, so I don't have the privilege of a wider-field guide scope. Quite often this past week I haven't had a wide enough field to find a bright enough star to peek up above the sky glow. PHD2 presents a gnarly grey noisy field, and "auto select" latches onto something that's often not a star at all.

I'd love to tweak PHD2 so it doesn't latch onto non-stars. I built a bad pixel map.

I'm not sure what issue you are having, but i image in the san fernando valley (the worst) and i have no problems finding guidestars, even with a simple lodestar x2. PHD has a number of techniques and filters to rule out non-stars for star selection, so i'm surprised you are having these kinds of issues

you might consider posting your logs to the PHD forums for feedback?

Re: Unguided with pointing model

Roland Christen
 


If my assumptions are correct, how much additional setup time am I adding if I plan to create a new pointing model after every setup?
A pointing model is something completely different from a drift model. A simple pointing model can get you to various objects fairly accurately and takes just a few minutes per point. You can do 3 on one side, 3 on the other plus a quick Orthogonality model. The whole thing takes maybe 10 - 15 minutes. However, that won't do a proper drift compensation.

If you want to do unguided imaging you need to do either a full sky model using APCC Pro (takes maybe 1/2 hour during twilight), or you need to model the path along which the object tracks during the night. That can take 20 - 30 minutes depending on how many points you wish to measure.

Subject: [ap-gto] Unguided with pointing model

I'm really appreciating reading about Roland's work to get pointing models into the keypad.

I've been doing a lot of imaging from home, LA County, with a Traveler, and an AP180EDT with 1100GTO. My biggest bugaboo in these skies is finding a suitable guide star. PHD2 will lock onto any clump of noise and hunt around the sky trying to guide on it.

I'm presuming that the same feat as Roland is developing for the keypad is available now if I go buy the advanced version of APCC.

I never did so because I stack my setup every evening and take it down every morning, whether I'm working from Sawpit Wash at home or GMARS in the desert.

If my assumptions are correct, how much additional setup time am I adding if I plan to create a new pointing model after every setup? (Is THAT assumption correct as well?)

Aside: I'm amazed at the results I'm getting from home. I never bothered to try it from here because I just assumed it would be a waste of time. Under the circumstances, I'm not interested in traveling anywhere (and having to use a public restroom perhaps along the two-and-a-half hour trip to get there). I just decided I'd run the Messier catalog for a quarantine project, and it's been fabulous. I'm documenting it all at http://mojo.whiteoaks.com

Best regards,
Mojo

Roland, this looks exciting, any ETA for release?  

This seems like a great feature for us mobile (non fixed installation) users.      Given how easy and fast this is, 5 minutes/hour of object tracking, will this be usable if you also have a PC connected (for things like plate solving) and do you use it with, or instead of, APCC?
