I've been testing Astro Pixel Processor software with integrating multiple sessions, from multiple nights and with multiple cameras.  Here's another take on the Orion Nebula with about 2.5hrs of total exposure, taken with my Canon EOS RP and 5DmkII on multiple nights.  My EXOS2-GT is performing very well, however, I'm still stuck in Houston dealing with lots of light pollution - I'm hoping to get to a dark site after the holidays settle down.

Imaging details as follows, sessions 1, 2 and 3/4 were on three different nights with different levels of seeing and varying PA with my portable setup:
Session 1: Canon 5DmkII, 1.53"/pixel res, no filter,  25x120sec @ ISO250,  20x darks, 100x bias, 50x flats, total PHD RMS error ~0.9"
Session 2: Canon 5DmkII, 1.53"/pixel res, UHC filter, 15x120sec @ ISO1600, 10x darks, 10x bias,  10x flats, total PHD RMS error ~1.1"
Session 3: Canon EOS RP, 1.37"/pixel res, UHC filter, 30x60sec  @ ISO800,  15x darks, 15x bias,  15x flats, total PHD RMS error ~1.4"
Session 4: Canon EOS RP, 1.37"/pixel res, UHC filter, 20x120sec @ ISO800,  15x darks, 15x bias,  15x flats, total PHD RMS error ~1.4"

Dr. Clay sherrod at arksky.org Arkansas sky observatory publishes ephemeris for comets etc.  Generally I guess you can poke in the ra/Dec to point the mount.  The rates won't be right though.  Perhaps PhD will guide you along.  Somewhere Jerry made a post about this.  SkySafari has these things and I wonder if it would drive the mount.  If I have time I will give it a go.  Same with satellites.  I wonder.

I haven't tried it yet but there is an ascot driver for sale that I found through cloudy nights.

Re: Pointer to alignment docs? #alignment

The best thing is to give it a shot, you can try the process but without the final step (which is actually physically aligning your mount) by downloading the free version of sharpcap.

Hello everyone,

Could be a long shot, but has anyone tried imaging comets on either iExos-100 or EXES2 using the PHD2 comet tracking feature?
I would like to try this but it's been cloudy here for over a month and for now I'm just trying to find if anyone had any experience.

Thanks!

Hi Jay

Nice blue and red M33.
This is M33 that I like colored.
Good photo Jay!!

I tried M33 3 times. with Z61 also. but never win.
Red not come.

No time for M33 any more in this season.
I must try again very soon.

Next time I will try Filter ,L-Pro and HA as you said.

Thanks Taro -- I think I got the FF backspacing correct now.

Here's a first light image with the WO Z61 of the Triangulum Galaxy from this past weekend (CLS-CCD filter). I'm interested to see if I can get more detail shooting NB with an Ha filter.

Re: declinition does not move sometimes

Wes Mcdonald
 

Rohan:

The iexos100 connects for serial via the USB cable.  Not an RJ-45.  The RJ port on the mount is for guiding via ST4 guide pulses delivered from a guide camera.  I believe this would be covered in the Programmers Manual which can be found on the Explore Scientific web site.  The manual is full of information useful to all, not just software writers.

The Iexos is rated to something like 9-10 pounds for astrophotography.  Other have used it with more weight to good results.  If you search the forum you can find posts about this.  For a camera only you are certainly fine.  If you want to go to a scope, you might start pushing the weight limit.  The mount performance can be pushed by lowering the tripod and perhaps by adding some weight to hold it down.  Also, owing to its overall periodic error, you will probably want to guide.  Short focal length scopes have pretty good results.  In fact the mount has had some every good results in other's hands.

Re: declinition does not move sometimes

rohan
 

thank you for the reply 
            i actually figured it out that the declination was not moving because the dec clutch above the counter weight was tight. so i loosened it and the dec started to rotate.Thank you for the help
     bt i had some more questions
  1) for a serial port connection the wire provided to me is a RJ45 6pin connector but to my laptop i have a RJ45 8pin connection, also a HDMI port and a USB port. i searched the market but i could not get any converter from RJ45 6pin to any of the ports available to me. so any option available
 2) I powered my PMC100 using a 12 volt battery. but there is no ON/Off switch available on the mount. so is that everytime when we need to switch off the mount we directly plug out the connecting wire. is it safe? 
3) Right now i am using a camera on the mount but in future i m planning for a reflector or a refractor telescope. how much maximum weight should the telescope mount have and what if the weight exceed the limit given will it damage the machine permanently??
thankyou for your time

Re: declinition does not move sometimes

 

Rohan,

Well, another scenario that would produce this behavior: <<the DEC does not move instead it gives the sound that its slewing but it does not rotate>>

Would be a loose setscrew on one of the belt drive pulleys.  I think we've had other posts with that issue.  

Corrective action would basically be to open the Dec motor case, and check the pulleys to see if one of them is loose on its shaft.
If one of the pulleys is loose, reposition it so that the belt is centered on the pulley and one of the setscrews is over the flat of the shaft (there are two on my pulleys, and I assume on yours as well). 
Tighten both setscrews - firmly but GENTLY - they are tiny.  Ensure that the belt is snug on the pulleys.  Close the case and test.

Here's a link to Alex's gear lash adjustment video.  It covers gear adjustments, not belt adjustments, but will give you an idea of what's under the covers and how to get to it.

Re: declinition does not move sometimes

Wes Mcdonald
 

Sounds like there are two things going on..

1.  The wrong direction moves sounds like location entry error.  The ascom driver comes with the default site being in Arizona, northern hemisphere.  If you are in southern that would do it.  Also stellarium needs to have you manually set your site in it.  I think it has a default Paris.

2.  If you hear motors sounds but no slew and you have the clutch engaged then what you are experiencing is a loose pulley in the drive.  Open the plastic door and watch the belt.  If the belt is not turning but the motor is running then the small pully on the motor has come loose.  If the belt is turning then the big pulley on the worm is loose.  Both pulleys are held on their respective shafts with set screws.  You have to remove the plastic housing around the motors to gain access.  If you go find Bob Hoskins paper on backlash adjustment in the files section you can see how to open up the plastic housing.

Re: declinition does not move sometimes

Chris Tardif
 

The drastic differences between what you're aiming at and where it actually goes can be caused by incorrect coordinates somewhere.  Check Stellarium and the ASCOM Driver or your other software for the correct longitude and latitude.  I had that last week, I should have had -79 and it was +79.   This can get unpredictable depending on which software pushes or pulls the coordinates from the driver.

Hi Jay

I use filter drawer and field flattener, it  show back focus and I setup near distance.
Can get focus then it's my back focus.

Attach pic my FF=FD=Camera line.

Thank you Taro --

I have a question regarding the Z61 and Field Flattener. Do you have to adjust the backfocus distance of the FF when using a 2" screw in filter? Do you use a filter wheel/drawer?

declinition does not move sometimes

rohan
 

hello its been a month since ive purchased the iExos PMC100 mount. I started it with the explore star app and it worked fine. later I tried connecting it with stellarium. for that i downloaded the pmc8 configuration software. and did the TCP protocol connected it via TCP. it got connected to stellarium but it did not slew in the correct direction where else it was showing a total 180degree shift in DEC. also after switching the connection to UDP for explore star app i was facing the same problem. later i uninstalled the pmc Configuration setup and decided to use only explore star app, but now when i am going for a star alignment the RA slews fine but the DEC does not move instead it gives the sound that its slewing but it does not rotate. i am preparing  for the upcoming eclipse event and need to sort this asap. please help

Re: Switching wifi/serial on android

Omar Rahman
 

One more thing...Jerry, thanks for suggesting the procedure for switching wifi/serial in the field without a computer. I used Connectbot on android to telnet and switch from wifi to serial with the ESX! command. And then back to wifi from serial using Cutecom on the Pi4. It all works great and I can switch from ExploreStars to Stellarmate and back without any trouble or unhooking any cables.

Thanks for your help!
