Re: Anyone successfully using SGP and Platesolving?

JI THERIOT <ji.theriot@...>
 

Jeremy,
I use SGP for imaging and haven’t really needed to use CDC. My flow is typically to do my drift align with PHD. Park the mount when I’m done, then I park and let SGP do it’s thing.  I find it typically more accurate that CDC. Every now and then I will leave CDC running in the background but I have never had issues with it. If I do have CDC up it is to get to a bright star for focusing. It’s usually the last thing I connect to.

Re: Anyone successfully using SGP and Platesolving?

Hi Jerry, Sunil,

Thanks for the replies. Jerry, I did also try the Astrometric J2000 as well and still had the issue.

Sunil, so with your setup, can SGP slew to a coordinate and CdC agrees? I did find that I could center very well using CdC to control the slew, after doing a 'Sync and Solve' in SGP. If I'm understanding you, I can use the plate solve coordinates to assign to a target in SGP? Ultimately, I will need to get SGP to plate solve to a previous night's image and slew to the exact center of the frame, because most times, my previous image was not on center with one star or DSO. Like for something like the Flame and Horsehead, it's somewhere in between them. I currently use the 'mask' feature in Backyard Nikon so I can overlay the previous image and use POTH to nudge the scope back and forth to align, then adjust the rotation if needed. But this is very time-consuming...

I guess I'm still confused about what exactly went wrong, and what coordinates were being passed to POTH. I probably need to take this carefully, one step at a time, with coordinates in hand from multiple sources on one or two targets I can experiment with. I should then note when I perform what operation, so that I can look back in the log file and make sense of it all. I do think SGP should be able to issue a slew command just the same as CdC, and then if that can work properly, maybe the centering routine will then work better.

Thanks,
Jeremy

Re: Pictures of PMC-8 Mounts - Let's See Yours

 

Renovations complete (for now, anyway... :-)
 
- I wanted to add a spreader (Done - see the MOUNTS sub for more on that)
- Adding heaters (and their 6 foot cords...) just pushed me over the edge on wiring, something had to be done!
- The top of my scope just does not have enough real estate to contain my Pocket Powerbox, a hub, and mounds of rolled up cabling.
- I do not move my mount with scope or weights attached, so the scope and its attached cameras and heaters all have to detach and reattach for a move outside.  The green tie is a Velcro strip that undoes for that, and while attached limits the dangle weight of the cable looms on the scope.
- No room up top, so the Powebox moved to a panel on the North leg alongside the PMC8.  The hub is on the other side of the panel, behind the Powerbox.
 
- Bob

Jeremy ,

                 I have been using SGP for the past 2 years and I have faced issues similar to you.The workaround that I use for the predicament you are in is that once you plate-solve (Solve & Sync)just use a frame and focus to go to your target in SGP.  Dont input values from CDC to SGP. If you want, SGP to CDC works. I am not near my mount right now but if possible can you try out my suggestion and see if it helps? This is one of the rate areas where the Gemini 2 had a better response.
So here's what you do : 

Plate Solve in SGP. If you want, enter the SGP RA and DEC values to CDC. ( Not needed if I am right).
GO to Frame and Mosaic Wizard and try to center a target. See if it works. I am sure SGP will try to center it for a while and once you are satisfied, then sync the target in CDC. DOing this the other way has always screwed things for me.

Anyone successfully using SGP and Platesolving?

Jeremy Parker
 

This is my post on Cloudy Nights, but wondering if any of you have ventured into Sequence Generator Pro?

 

I've decided it's time to get into SGP, and I've made some good progress with the help of the online manual, Alex McConahay's 'SGP The First Week', and I even caught a bit of the Plate Solving episode on TAIC this past weekend. So thank you all for providing this helpful information. I am running the trial version, with one indoors session and one outdoors session under my belt. I am having some issues, but here are the things I think are working:

  • SGP can connect to and communicate with all equipment (D5300, mount via POTH, and PHD)
  • PlateSolve2 is working (recognizes images I feed it manually AND images taken by the camera in SGP, I learned about keeping image nebulosity low, not too many stars, etc.)
  • 'Solve and Sync' seems to work well, then slewing to nearby target in CdC is accurate within less than a few pixels
  • Can run a sequence successfully (guiding starts, light frames, dithering/settling, stopping guiding and tracking afterwards)

The problems that I'm having are the following (which may be the same problem?):

  • Once the mount and CdC are synced to the location from the platesolve using 'Solve and Sync', SGP can't seem to accurately slew the mount to coordinates I copy right from CdC using 'Slew Now' or 'Slew to Target'. I'm using the 'Mean J2000 (mean equinox and epoch J2000)' setting in CdC. But like I mentioned, if I use CdC to slew to the target, it's right on.
  • Once I'm near my target, the 'Center Now' or 'Center on Target' can't seem to get within say 15 pixels (or 16+") of centered, even after 5 tries. 

I've read most of Stelios' post on what I thought was a similar issue, but even after trying all the coordinate settings in CdC, it still wouldn't work. CdC/POTH seems to receive the correct location from SGP after a 'Solve and Sync', but SGP can't seem to issue an accurate slew to even the same location it was synced at. Does anybody have any suggestions?

 

Thanks,

Jeremy

Hi Bob,

Yes I agree. SYSHELP has not seen but 6 message threads and I don't think any new members have joined since I created it. There are only 97 members of the subgroup. We now have about 150 in the main, so the bulk of the new users for the iEXOS 100 mount have not joined any of the other subgroups.  I think making a sticky post about joining the other subgroups makes sense. I was also going to put a big bold red headline at the top of the MAIN group home page to please join the other subgroups, maybe that would help also.  The alternative is to send out a weekly reminder to please join the subgroups if you are new to the forum.

Jerry,

As a very new iEXOS-100 user, I’m interested in anything that will help me out.  Fact of the matter is — the weather has been so bad here that I’ve not been out to use my new scope and mount since it arrived in mid-Jan.  I’ve played around with it a bit using some imaginary slewing and tracking just to try out the hardware and software.

What you might do for new users in general, is put a sticky post (Say... "If you're having trouble, have you searched the KB...?") at the top of MAIN's 'Messages', carrying the same KB link as you have on the HOME page.

WIth ASCOMPAD 2.09 installed, I get the same behavior (running WIN10 in VMWARE on Mac) but if I drop back to ASCOMPAD 1.2, the software takes the button settings and the gamepad moves the mount.

Re: Stellarium and ASCOM

Okay Guys, I want to play.  Can the ASCOMPAD/Gamepad be used with the ASCOM WiFi setup?I've have done all this before but it was with a serial connection. 

I just can't seem to get my XBOX 360 wireless controller to move my mount.  I can see it in the ASCOMPAD setup menu and even change some of the buttons in the settings menu. It even allowed me to calibrate the joystick.  However, when I try to move the mount, I can hear a faint whirring sound but no motion.

I'm using a Windows 10 tablet PC that automatically connects with the device when I plug in the base to the controller.  I have no problem moving the mount with the POTH virtual of either.

Any ideas?

Thanks,

Darryl
