Can’t see it.  Can you make a still with it circled?

And I have this question:

If Mickey is a mouse
And Donald is a duck
And Pluto is a dog.....

What is Goofy?

I decided last week to try to photograph Pluto since it was the only "planet" that I hadn't photographed yet with my EXOS-2.  So I used my plate solver to aim my ES 102CF and took about 40 - 1 minute exposures.  After stacking the pictures I soon realized that Pluto must either be too small or it must look like just another star because I couldn't find it in the hundreds of stars in the picture.  So I decided to repeat the process the following day and then compare the pictures to see what moves.  That would have to be Pluto.  My friend who is the head of the Astronomy club here in Lexington told me that's how Clyde Tombaugh found Pluto in 1930 although he used a mechanical blink comparator contraption to look for movement.  So I did that the modern way by using Affinity Photo to align both pictures and then made a short movie switching back and forth between the them.  I'll attach a link to the video here:
https://www.dropbox.com/s/unhlttvs1ncha10/Pluto%20Blink%20Comparator.mov?dl=0
You can play this video in a loop and replicate with today's technology what Clyde did back in 1930. Pluto pops out if you look closely.  This would be a terrific science experiment for a high school student if you ever need an idea!

Hi I am new to this, had my EXOS 2 PMC8 for a couple of months now and everything seems to be working fine apart from I cannot take images for longer than 60 seconds without getting trails. 

I have been using Sharpcap 2 with a Altair GPCAM2 290C for polar aligning attached to Skywatcher Evostar Ed80, I get exelent according to sharpcap. 

I then slew to an object in Stellarium but am always off? 

I amusing POTH hub and connected to laptop via serial port.

I will be trying N. I. N. A. soon to see if there is a difference. 

Any help or suggestion welcome. Thanks

If your using an exos 2. You may get errors in the guiding. Check the cables and balance. Its quite hard to balance in dec. In fact really hard! The cables make it even harder. Play with the cables and see when it's happy. Take pics for future ref.

Subject: [ESPMC-Eight] Tracking
 
Hi I am new to this, had my EXOS 2 PMC8 for a couple of months now and everything seems to be working fine apart from I cannot take images for longer than 60 seconds without getting trails. 

I have been using Sharpcap 2 with a Altair GPCAM2 290C for polar aligning attached to Skywatcher Evostar Ed80, I get exelent according to sharpcap. 

I then slew to an object in Stellarium but am always off? 

I amusing POTH hub and connected to laptop via serial port.

I will be trying N. I. N. A. soon to see if there is a difference. 

Any help or suggestion welcome. Thanks

Thank you I was watching as you replied. I am assuming that PHD2 keeps the speed correct with the auto star selection? I have been using ASTAP plate solver would you recommend a different one? Thanks

Hey I have done a vid. On a sequence in nina without polar alignment. I have 5 mins subs doing this routine. Normally stick to 3 though as quicker ;-) https://www.facebook.com/groups/775235275932996/permalink/2990943017695533/

Sorry for the confusion, I thought the two were the same firmware.

The iEXOS 100 mount does not have an "a" version of the firmware because the firmware never had the communications watchdog enabled.
Only the G11 and EXOS 2 versions of the firmware (9TXX) had the watchdog timer.

Technical drawing or stl for polar scope adapter #iEXOS-100 #polaralignment

John Wells
 

Hi, 

I recently purchased the iexos-100 and am trying to find a reliable way to mount my polar scope.

I've already tried mounting it to the lower control box by 3d printing an adapter, removing the two m2. 5 screws and replacing with longer ones - - similar to the commercially available polar scope but on the lower box. 

However my design impinges on the scope a bit when imaging near the meridian, and it was also only tight briefly... slop keeps appearing. 

Would like to try printing or CNC machining a bracket like the commercial mount for the top control box. Are any technical drawings available? 

Also any advice on how to reduce slop if it really is only held on by two m2.5 screws. 

I understand you might not want to share the drawings, but I've already purchased the scope and az adjuster, and already have the polar scope I'd like to use! 

Thanks in advance, 

John

Jerry,

Thanks for responding.

I bought the mount on 13 Aug 2019. I don't remember updating any firmware, but I could have as I was trying out the PMC 8 config tool sometimes in the past. The mount was shelved for almost 10 months as I was not very impressed with the polar alignment process on this mount where you have to loosen the mount and turn by hand. Got the alt az adapter few weeks back and getting now to use the mount finally.

Updating the firmware seems to have fixed the problem.

Thanks,
-vijay
