I just understood what Rolando is saying, that's a good idea - cover the unit itself further with a Ziplock bag...

Hi
Can I use my hand controller that was used with my cp2 and ap600e when I get my cp4?
Do I need to update it somehow?
Thanks.

Re: Mach-2 can not reach target

Thanks Greg, most of my settings are the same as yours, and always glad to re-confirm so thank you,  except for minutes past meridian I had set to zero in SGPro.   I was hoping to test out delaying the flip in SGPRO by 15-30 min, slight counterweight up before doing the flip, but the forecast showed 10% rain potential and 20% in the morning, so disassembled everything at 1am (I wasn't going to flip until after 2am..)     I need more than 5 hours of sleep.. given I'm still working.    Based on the error messages and way it was working, my suspicion is that the mount was trying to center very slightly east, when either the software or mount itself wanted to limit to the west side after the flip.   This could be because there is some orthogonal error on this wide field scope (400mm f5).    
I still want to check 2 things, time and sky cooperating, one is delaying the flip and two is I unchecked a box in APCC that limits flip point to meridian (but maybe it does more).

Re: Multiple limits set?

 

Thanks Konstantin

I have not used Home position, but i have defined it, so maybe i'll turn that off and see if that makes a difference

Hi,

it seems that there is a bug. I reported that a while ago with a Mach2. I am sorry but AP is not reacting in this case. Ray is mentioned that is a firmware foult and Howard is working already on that bug. 
You came out of that situation, when you use find home mostly. Then you can use the mount again in common way.

Hi folks

Where are all the places you can set limits? We have AP1600 with encoders

we turned off AE limits in APCC as a test, and we're still getting errors that we've hit the RA limit and it's bouncing back. I know 'bounce back' is an option for setting limits, but it seems they are being applied from another screen or program? we are just using SGP for now. 

any pointers appreciated. thanks

Ditto, I keep the Telegizmos open from the bottom so the air circulates and the mount stays out all year around. The rain must have happened during one of the sessions in the night.

I had the first run with the mount the other night and with an average seeing achieved sub 0.4 guiding constantly. I don't recall that happening too often previously so the new PEC curve must be an improvement. Here's the mount back in work with the 17 years old TEC on top of it.

Thanks Bryan

yeah that's what i thought - i definitely have those disabled and yet it is still hitting limits

Sounds like AP is already aware of this

Click the Edit button on the Horizon Tab.  same for Meridian limits.

See Section 5.15 and 5.16 in APCC Pro Guide for details. (Page 144 onwards)

Re: Multiple limits set?

 

Just a quick follow up:

i have no meridian limits set in APCC either. I could not find any limits to set in the ASCOM driver

I LIKE the laser pointer holder. That is a great idea ! Is that designed specifically for the purpose, or is it just one of the dovetail finder brackets ?

Rolando, I am like Terry and would also like to see your setup. I would like to use my 105 Traveler piggybacked on my 160 Starfire but am using a 1200 GTO mount that I’m quite sure is capable of handling it all. Can you confirm this as well as show us your set up? Thank you, Max

Re: Mach-2 can not reach target

Greg Vaughn
 

Hi Terri,

 

I guess I’m fortunate that I have had no issues with my meridian flips using  SGPro, connected via the ASCOM driver and running APCC as well.   I set the meridian flip to 10 minutes in SGPro and don’t do anything special with APCC or the ASCOM driver.

 

As I’ve mentioned before, I think, I use ASTAP for my plate solver.   I also have the plate solver set so that it selects the LUM filter and 2x2 binning for plate solves (which may be unnecessary but has served me very well for ordinary plate solves and APPM).

 

In  case this helps and at the risk of telling you what you already know, find settings for Meridian flip in SGP under ‘Telescope’ in control panel – check ‘Use Auto Meridian Flip’ (under heading ‘Telescope Options/Data’), then click ‘Set’ to call up the Meridian Flip Options menu.   I set ‘Minutes Past Meridian to Flip’ to 10 minutes (default?) and then I click ‘Auto center after Meridian Flip’.

 

Most of my meridian flips have been North, not South, since past South I’m in the trees except at very high elevation.   However, I’ve imaged several targets before and after the northern Meridian flip, such as Eastern and Western Veil and the Bubble Nebula, automatically and without any difficulties. 

 

This is using an AP130 and not an SCT on a Mach 2, so I suppose your mileage may vary depending on your equipment.

 

Good luck sorting it out.

 

Cheers,

Greg

I have seen something similar when I am running my SBIG camera in the continuous focus mode and then I stop it. The last image has a similar appearance.

Re: Spiderwebs in the sky

All points on the same side. I started with the first point on the object while it was some 3.5 hours in the east, then added 4 more points until i got to the meridian. I actually took one point about 1/2 hour past the meridian and my last image was taken with the scope about 1 hour past the meridian.

I lost a number of subs when my QSI camera messed up about 1/2 way thru my session. Once in a while the image has a herringbone zigzag pattern that only goes away when i cycle power to the camera. I was busy working inside and did not notice the problem until an hour had passed.

Has anyone ever seen this kind of defect, and what could be causing it:

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

Roland Christen
 

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 ?
