Were all 5 points with the telescope on the same side of the mount or were one or more points from the other side?

Re: Spiderwebs in the sky

The image is done at 1x1 binning. If you look at the bottom of the screen you can see that it is set to record the full 3326x2504 pixels.
The image is done with settings in Autosave, which has different settings that what is shown on the screen. The 4x4 is for quick 1 second grab to locate a star for focus purposes.
Autosave is independent of Find DSO or Focus or any of the other exposure presets.

As the temperature drops a refractor's focal length shrinks faster than the tube shrinks, so focus has to move inward.

Great shot Roland

I also have some questions about your MaxIm DL settings:

Do you always image using the Find DSO setting ?

I think I read somewhere that the sub-frame box should not be checked when you are taking an actual image. I am not exactly why, but I see that yours is checked. Is this for the focus tweaking ?

You mentioned that you tweaked the focus during the imaging session. How do you know which direction to move it ? Is it reasonable to assume that as the OTA cools down it will always shrink, and therefore you would need to rack the focuser out ?

I can't tell if I am looking at it correctly, but it looks like you have the binning set at 4X4. Is that correct ?

+1 for ease of use.

It would be nice to get some expanded plate solve options for people that dont use SkyX, Pinpoint, or SGP. ASTAP or Planewave Platesolve2 would be good. I use SkyX for this, but it's the only reason why I have SkyX still. Everything else in my system uses ASTAP or PS2.

I used the simple keypad routine. However, if you are permanently set up I would recommend APCC-APPM. It comes with the mount. It can do a whole sky modeling run while you are having dinner.

Very nice image.

Was the modeling done with APCC/APPM or with the new keypad feature?

Yes, that's right. Each exposure was 600 seconds long. I took the screen shot during one of the exposures.

Re: Mach-2 can not reach target

SG Pro just talks to the ASCOM driver, so whatever the issue is, it is not likely to be something SG Pro is doing.

Thanks Konstantin, I'll wait to hear what's happening on this thread before pursuing anything with SGPro.     It's wild that it just started to occur for me... Been imaging with updated firmware load (sent my mount in just before Neowise) for updates.    I've used it quite a few times since being updated and this error just started occurring over the last 2 days.

I've now had it happen on 2 different targets.   I use SGPro as well.. so I was using SGPro plus APCC plus the ASCOM driver.

Are you using SGPro and/or were you imaging right around the meridian?

I've purchased the Chroma 3nm filters because I couldn't get Astrodon in any predictable timeframe.. Chroma filters are made right here in Vermont!      

I did 5 hours on SH2-155 last night in narrowband, lost my last hour due to the snafu I shared with mystery RA limit error.

I can easily believe this. I’m using a rain app but it’s not bullet proof so I’m sure the unit got wet at some point. Unfortunately this is the best I can do at this point. 

What’s interesting is that when the first symptoms of the yellow light occurred and I had issues for a few night , suddenly the mount worked just fine for a week after that again.

Hi Astronuts,


I enjoyed several nights of clear skies and good seeing, so I was able to image some deep sky with my 160EDF refractor, Mach2 mount and QSI CCD camera. I modeled 5 points along the object's path and did 19 exposures total, 10 minutes each. The 160 refractor is a handful, plus I had my 92mm Stowaway riding shotgun, but the mount handled everything beautifully.  just posted the image on AstroBin:

For those of a technical bent, here is a screenshot of the RA and DEC path that the modeling produced over a period of about 1 hour. Two little blips on the RA trace was caused by me touching the focuser, refocusing the image:

Mach-2 can not reach target

Konstantin von Poschinger
 

Hi Ray,

I have again a little trouble. I was imaging in the east. Then I slew to the next target. The mount chage the side to pointing west. Cause the target was a little in the east side of the meridian it tryes to reach that point but the mount stopped with a error, that the RA limits are reached. I can’t came out of this, eaven a finding home (park 3 position) didn’t let me clear the error. I had to park and shut down the mount. After that the mount worked normal.
I have saved the Logs!

Can you find out if I have dane something wrong.
The other question is, have you found a solution für the posts I have send last week?
