Re: Scope Location and NINA
Russ Is it possible you have Set Gemini time and location on connect in your Gemini application?

Scope Location and NINA
Constantly having the same issue when connecting scope to NINA, MAXIM and any other software.? Tonight for example, the G11 HC (physical device) shows my location (LAT/LONG/TIME) correctly.? However, when connecting to any software package (like NINA) and I look at the virtual Gemini HC on screen, shows my location as Hollywood with everything zeroed out.? When I then try to slew to a star it is way off.? Also, the Gemini Virtual HC will not let me enter a new LAT/LONG/TIME.
Anyone else come across this issue???? |
Re: Spikes!
haha well i'll say it one more time? "this doesn't directly address your question, but i think having a solid foundation is an important first step here" Fixing symptoms with unknown?causes is always a process of elimination right? if we knew what it was, we'd just jump to the fix. But 99% of the effort is isolating the cause. So it makes sense to me that we want to make sure everything else is operating correctly, and eliminate one thing at a time that's also why I mentioned the previous steps of doing an unguided run. if it shows up in the unguided results, we know it's the mount. if it's not we know it's not the mount, or at least not the mount by itself i like your idea of testing without the SCT On Fri, Apr 2, 2021 at 2:12 PM Jamie Amendolagine <jamie.amendolagine@...> wrote: I made a habit of making large steps for calibration sometime ago, and I honestly can't remember exactly why I did that...

Re: Still working out polar alignment on my mount
Hi Jeff Are you referring to a reset to default values? from your hand controller main screen MENU->SYSTEM->RESET HGM DEFAULTS then power cycle the Gemini After that I recommend doing a Quick Start and walking through the setup info If you change your mount type (and I think you?will: you have a G11T correct?) you will want to power cycle your mount again after that On Fri, Apr 2, 2021 at 1:15 PM jeff marston <jeffmarston@...> wrote: How do you do default setting for anything on Gemini 2. I haven¡¯t found a video that shows that yet. I have looked through the menu and I haven¡¯t seen it. It has to be something obvious I just missed. --

Re: Spikes!
Henk the backlash calibration looks fine to me? southern movement is not part of the calibration you're right they are both too big On Fri, Apr 2, 2021 at 12:53 PM Henk Aling <haling@...> wrote: From the calibration graphs, it's not just the RA that has steps that are too large but the DEC calibration steps are almost all backlash clearance (the ones labeled B).?

So, major DEC backlash problems during the calibration at least.? The large RA steps indicate there's something wrong in the settings, and PHD2 will therefore use a gain that's way off.? That could explain it. Now, if I could only fix my own guiding problems... |
Re: Spikes!
Yes, as I mentioned this doesn't directly address your bumps, but I think it's important to make sure everything else is working correctly Another thing that would help is a longer unguided run like 30-45 min (guiding assistant or disable guide output) If there's a problem in the mount, it will show there as well might also doublecheck?PEC status and and TVC values On Fri, Apr 2, 2021 at 11:44 AM Jamie Amendolagine <jamie.amendolagine@...> wrote: Thanks, you're right, I don't have very good calibration.

If that fixes it, then there might be something going on with the SCT, or image train on the SCT.? --

Re: Spikes!
PHD recommended min limit for image scale is 0.5" so i would?bin 2 at a minimum all of your calibrations are problematic? here's a typical example the calibration run should be 25 pix across 12 steps, which is shown in the outside circle of the target here: you can see you have only one step in the circle if i zoom way out i can see the rest of your calibration, which looks okay, but the step size is way too big So i don't know what your settings are, but i recommend you bin 2 the guiding and start with a fresh equipment profile this doesn't directly address your question, but i think having a solid foundation is an important first step here On Fri, Apr 2, 2021 at 9:50 AM Jamie Amendolagine <jamie.amendolagine@...> wrote:

Re: Spikes!
Yes, using my 178 it should be 0.35 when using the OAG. I have binned it in the past but found that it didn't seem to help, so I just leave it native.?
Using my 1600 it should be 0.55 according to https://astronomy.tools/calculators/ccd_suitability, it should be 0.55 because of the 0.7 reducer.
?
I put in a focal length of 1471 in the PHD2 wizard. Which is not exactly the spec for the scope with the 0.7 reducer (1422). I did this because the solver complained that my calculated focal length was actually?1471, not?1422, so the image scale is slightly different than what astronomy.tools reports.??I think that I calibrated a few times as I was trying things out, so there should be several in there.

Re: Spikes!
Jamie is your pixel scale really 0.34"? the calibration looks really wonky too (or as a result) On Fri, Apr 2, 2021 at 9:03 AM Jamie Amendolagine <jamie.amendolagine@...> wrote: Here it is.? --
