Hi,

1) i’m new to the mount too, but believe I’m right in saying that once you have aligned press SYNC first and then Enter. 


2) Select an object and press ‘Slew to object’ and the screen will change to the detail page for that object, now press GOTO and you should be in business.

Someone more experienced will probably correct everything I’ve just said, but this’ll give you something to do in the meantime 😂😂

Hi all!

I just got my iexos-100, and will be using it with a Rebel T6, and lenses, no telescope. I currently have the 75-300mm kit, 18-55mm kit, and the 50mm 1.8 lenses. I had a few questions I was hoping some seasoned pros could answer, as I am VERY new to this. I got everything setup, and ready (supposed to be clear tonight), and will be doing a 3-Star alignment as I cannot see Polaris from my yard due to trees.

Once aligned, I know I can slew to an object. Once it slews to the object I want to photograph does it track it, or is there an extra step?
With my lenses I usually use the 75-300 at 300 set to F5.6, and 6400 with 2 second exposures, what would a good setting be? Would I be able to do 30 or more seconds?
I'm assuming I can still have my intravelometer attached to the camera for setting exposure/interval and all that.

I really just want to make sure I don't get out there tonight, and just end up frustrated, or searching for an answer.

Thank you,
Daniel
Hi Daniel, your set up is identical to mine. For starters, although I don't view unless I can see Polaris, and point to it, with a three star alignment I'm sure you are good to go as long as your mount is level and pointing as close to true North as you can manage.
My mount tracks very consistently and accurately, I find up to 2 minute exposures to be fine. With the light pollution I have to contend with I find ISO 400 is about the best with anything more than a 10 second exposure, you just need to experiment basically.
Regarding tracking I understand that Tracking is preferable to the Pointing option when two or three star aligned. When you have completed the alignment process, and you now pointing and synced to your target you will find the tracking option is selected by pressing one of the UDLR buttons momentarily if the app shows P (pointing) mode.
Hope that helps, Brian

NEVER hard tighten screws that go into ANY kind of plastic. That is a sure recipe for stripping the threads.

I have no idea what the nuts are for. Those are not shows in the parts list included with the directions.

Again, please contact Bresser customer support.

We have a draft document for using the finder. But is has not published

In a nutshell:

1) Look in the sky and find Cassiopea and the Big Dipper (The Plough in Europe, I believe).

2) Rotate the Polar Finder Scope to match what you see in the sky.

3) Adjust the mount in azimuth and altitude to get Polaris in the location on the reticle.

The other marking are for use in the Southern Hemisphere.

The procedure outline above is done once the Polar Finder Scope is aligned with the polar axis of the mount.

Note that the only way to ensure a perfect polar alignment is to use the Drift Alignment method.

Camera alignment programs like Pole Master, Sharp Cap, etc., provide extremely close polar alignment. The Drift Method makes it absolute.

No printed directions. I just found the manual online on your website.
Is there anything else available in printed form?

Those slightly oversized nuts were placed in a small plastic bag
together with the screws (actually pulled "demonstratively" on them!)
and a 2mm hex wrench. Without the nuts used as washers, I wasn't able to
tighten the screws on the mount (well, I probably didn't use _all_ of my
power, but it seemed to be dangerous to try any further).

Best regards,
Pavel

Pavel,

The packages from Explore Scientific do not have nuts. The box does
contain two screws referenced in my answer to Ade.

Noob question #iEXOS-100 #alignment

Daniel Burdziak
 
Edited

So I took my new iexos-100 out last night after rigging a way to mount my Rebel T6 to it, until I can get the dovetail, but I have a couple of questions.

1) I cannot see Polaris from my yard, so I went with the three-star alignment. On my kindle fire when I do the alignment it shows "previous" "enter" "next" as options for a star. First question is, when I manually move to the star and have it centered on my camera screen, do I just hit enter? Or do I have to move the dot that is on the "map" to the center of the screen also?

2) Once I did the alignment (at least I think I did), I didn't notice the tracker moving at all when I would slew to an object (It would slew to the object, I mean it wouldn't move AFTER arriving, so it wasn't tracking it). Are their other things I have to select before it begins tracking?

I appreciate all of the help i've been getting. I've literally been doing Astrophotography for like three weeks, and this is all very overwhelming.

Ade,

I checked email but found nothing from you on this subject.

The specifications on the replacement screws are M2.5x20, with thread M2.5x0.45mm, using a hex/Allen tool that is 2 mm.

The part in question is McMaster-Carr Part No. 91292A019

On the units I have assembled things fit perfectly.

Did you receive a set of printed directions?

Hi,

I have just received the Polar Scope yesterday from Bresser/Germany and
also was a little bit puzzled by several things:

From the package, the scope was loosely fixed to the mount adapter
plate, but the other way around than it should be, as I found out
quickly. The people in the factory obviously do not care much and let
you solve the puzzles youselves.

The two small screws were accompanied by two oversized nuts without any
obvious purpose. I also found out that the screws are just too long, so
the nuts are obviously expected to be used as washers (underlay)? Even
so it was very tight to get fully fixed, but fortunately nothing got
broken. I guess it would be more appropriate to shorten the screws by
cutting them or just to buy shorter ones, but as a workaround it is OK.

I am also puzzled by the role of the rubber washer or gasket (or how
should it be called?) just loosely pulled around the scope...?

The reticle would also need some explanation that I have not found
anywhere. I suppose that Polaris should nowadays fit exactly into the
gap in the line between the marks "2000" and "2030" - and in the
following years maybe behind the line and closer to the mark "2030"? (As
the Earth axis slowly drifts... But it should drift slightly *pass* the
NCP, not directly *towards* it, I think.)
A similar explanation would also be useful for the triple line/gaps for
"δ Umi" and "51 Cep". Why triple?
Anyway, I have not really found "51 Ceph" in any catalog nor sky map. Is
it possibly the star marked as "OV Cep" or "HD 51802"?

I hope to actually try looking at the sky with the finder tonight. Last
night was rather cloudy.

Best,
Pavel

Hi all, has anyone else installing the iEXOS-100 EXOSPF Polar Finderscope?

The two mounting screws provided are supposed to be M2.5 x 20 according to the Instruction Manual, but appear to have a smaller nominal diameter than 2.5mm.

Thankfully, the smaller diameter means that they are tight replacements for the two smaller screws in the front of the declination drive's cover, but at 20mm they are too long to thread all the way in.

One of the longer screws was so tight that I couldn't remove it with the Allen key and had to resort to cutting the screw's head off and removing the threaded portion with pliers.

If the supplied screws are indeed M2.5 (they look no more than M2 in the accompanying image of the only good one remaining), would two 15mm-long screws be better?

Many thanks,

Ade

Re: Exos2gt balancing weights

Chris Tardif
 

I believe that is correct.  The further the weight is away the more likely you are to get flexure in the counter weight rod. More weight closer to the mount will be more stable.  It's minor, but its true.

No dice was worth a try though. The ready light doesn’t flash with it still and this time the terminal doesn’t seem to be receiving properly.. just shows a strange ‘y’ looking character over and over. 

Thanks though was definitely worth the try, if even to learn it doesn’t help. I will wait for the ftdi adapter to arrive. I’ll just have to be patient.

I believe it is true that if the dtr line is in the wrong state, which it had been reported by others to be, it would cause the pmc8 to reboot.  I don’t know which state it should be in though.

You could make a straight thru db9 connector that passed pins 2,3,and 5 only which would allow you to test this out without busting up the plug.  

I k is the dtr line left floating (unconnected) works fine for commanding the pmc8 via serial.

Exos2gt balancing weights

Kevin Rea <reakevinscott@...>
 

Hi guys,
I use my Celestron C8 on my exos2gt mount.
I have been using just one counter balance weight to balance the scope.
It came with two of the weights.
should I be using both of the weights so I can move them up towards the center of gravity balance of the scope ??

Thanks,
Kevin Rea

Re: Trouble setting up Exos 2 mount #EXOS2 #ExploreStars #ASCOM

Do you mean that the dtr is not required for the pmc unit and that it might be actually triggering it to start the connection (maybe even repeatedly)?

I ask because I’m unable to open the adapter. unfortunateIy didn’t read the Stores current return policy when I bought it and they have a final sale policy in place as a part of their covid policies. Soooo if that pin isn’t required and might actually be causing the issue, Thrn maybe physically removing it would be just as effective?

I know this is by no means a for sure solution, but if it didn’t work then really no loss since I’m never going to use that adapter for anything else.

The dtr line is the culprit I expect.  I think you can find a program out there to set the prolific dtr line to the opposite state.  Also if you feel frisky you can maybe go into the sb9 in the cable and disconnect the dtr line.  This will prevent the constant reboot but it will make it unable to do a software update

Re: #astrophotography #goto #iexos-100 #iEXOS-100 #astrophotography #goto

Chris Tardif
 

Start with the wider end and work your way up.  If you're going to go to the 300mm range of your lens you will want to think about autoguiding.  With that you can get nice long exposures.  Otherwise you're going to be sticking close to the 500 rule:

This 500 rule: https://astrobackyard.com/the-500-rule/

Not this 500 rule: https://www.youtube.com/watch?v=q_Hxkex87jY (Warning, Dylan O'Donnell & salty language) 

This guy just landed a good video: https://www.youtube.com/watch?v=2oiTVGA2zIs 

You can bolt a small guide scope onto the camera with an L-bracket.

Hi Daniel,
 
for me (with also 300mm f5.6 Tele-Lens) best combination was ISO1600 and about 10-15sec exposures. Higher ISO was not satisfying for me, as there was too much noise in the pictures.
I could only reach longer exposure times with correct polar alignment, but never more than 30sec.
So you should try what fits best for you, I don´t think anybody can tell you.
