Hi Perry,
   The UK dealers are also out of stock,  but I found  one on Amazon UK.  The price was higher ($50) than UK cost but free delivery.   I discovered that it came from Germany taking some time.  The  website implies that it will be back in stock mid October.   

Cheers,

Ian

Small and light for one thing, a belt drive for another but the greatest reason was the fact that it has adjustable clutches in RA and Dec as does my GM8.  For wide field imaging one does not need 'goto' so I have simply activated the mounts motors - so it will then continue tracking at siderial rate and adjust the clutch tensions so that I can manually move the scope to the region of sky that I want to image and the telescope/lens will keep pointing when I cease the pointing adjustment.  The full frame Sony Cameras that I am using allows one to 'see' the starfield in live view to align the telescope and camera on the region of interest which the mount then follows.  Simples.  (Now in UK dictionary.)
I polar aligned using a laser beam through the RA sighting tube.

Three images:
1) First light of the mount of the Deneb region using a Teleskop Service 65mm, 420mm focal length, Quad astrograph.  Sony A7 II with stacked 30 second exposures.

2) I have tried to 'observe' the tracking performance by 'tracking' a fixed artificial star and find it very difficult to spot the tracking errors.  I have edge detected the track and the variation seems to be only 2- 3 pixels.

3) The Sword of Orion.  Takahashi FS 60 and Sony A7S.  Composite of three 'panes' aligned and stacked in Sequator.    Nothing special, but the Orion, Running Man and Flame Nebulae are there.  Full image is ~30 megapixel. This is 25%.

So I am very pleased with my purchase!  (From Germany as UK dealers are out of stock.)

Hiya,

Not using astroberry specifically as I rolled it all together myself on the pi but we had very similar problems to yourself with Ekos/Kstars and the iExos-100 and it got compounded by using a polemaster for alignment.  Similar to yourself what we tended to find was that after setting the camera to the NCP in the "home" position (i.e. counterweight bar straight down, camera pointing at Polaris - using a vixen plate directly, no ball head) and then plate solving we would try to do polar alignment and it would rotate in all kinds of strange directions (and frequently fail to plate solve from the polemaster in the process).

What we had to do was use an iterative procedure to fine tune things as it seems a single solve isn't always good enough for the mount to know where it is so what we did was;

Roughly polar align the mount - I find the polar tunnel impossible to use so I broadly eyeball it and then my wife uses liveview on the camera to see if we're in the ballpark.
Solve (with the action set to sync rather than slew)
Slew to a target not super far away from polaris - it'll quite frequently end up nowhere near.
Solve again
Slew to another target - it'll likely to be much closer now
Solve again
Slew once more and it'll normally be bang on.

Then we'd run PA with the polemaster and it would typically solve quickly and slew correctly during the procedure

Finally once PA is dialled in tight a final 1/2 solve and slews would set us up for the night.

It's a bit of a faff to get the mount dialled in but it only takes a few minutes and you only need to do it once per session.  my working hypothesis was that by having the mount quite a way off PA the solving gets a bit messy and whilst it solves it's not fully sure on the absolute position of the mount and get's it wrong.  A few repetitions fixes this by giving it more data to work with.

Hope that Helps

Jacqui


locked #iEXOS-100 using Ekos and Kstars, problems when running GoTo #iEXOS-100

Mehdi Tlili
 

I have a raspi running astroberry and could successfully connect to the mount using USB.
Everything seems configured correctly but I do not really know how to initialize my setup before starting a photography session.

What I did try was to approximately polar align the mount, then release the clutches and move the axes such that the camera is pointing at Polaris (Camera is currently mounted on a ball head but I try to keep it parallel to the polar axis as much as possible).

Then I run plate solving in Ekos and get the correction. The mount then slews to that direction to center Polaris in the camera.

The next step is where the problems start. When I chose a new object in the sky and command to mount to slew to it, it goes to a totally wrong direction. Kstars shows a right motion in the sky map but the camera goes to a position where it is pointing very far from an obvious object (Andromeda for example). I couldn't really understand what the problem was. Also, when sending back the mount to Polaris, it does not go back to where it was initially.

Did anybody get the iEXOS-100 to work with Ekos and faced similar problems? Some hints would be helpful.

Also, sometimes the mount becomes very loud when slewing and seems to get stuck for a moment. The noises are quite scary, sounds like it will break or something. What is that?

I attached a picture of my setup.

Glad things are working for you.  As an armature who has some great results with the ecos2, I appreciate having your professional feedback.  

A few questions/points

1.  To get the mount tracking are you using explorestars?  If so be sure to put the mount in T mode which moves at sidereal rate in RA.  I presume your were.  P mode moves the mount stepwise with 200ms intervals.  Fine for visual, not so for photos.
2.  The goto function would obviate your need to break the clutches.  Might be fun for you to use it
3.  How did you have it track a non moving target?  I would love to see how you configure your artificial star.  
4.  Baring ra and dec drift from poor polar alignment stars should move by the amount of PE present, right?  I figure you observed something like 12 “ PE.  This is really good for the mount.   Btw the PE period is 600 seconds.

cool - what material did you use ?  My little printer won't really do ABS reliably and I was concerned that PLA wouldn't have the material strength to handle the force required which is why I used a steel square (although I have a tendency to over-engineer for things like strength).

well it's pretty easy to dismount so I took it off and took one



for size reference it's about 42mm high and 67mm long and I used two 16mm wide x 2mm thick corner braces to construct it.  the thumbscrews are M6 x 40mm and the mounting slot is a small piece of 2mm thick slotted angle steel.

Hi All,

Thought people may be interested in this.  My wife purchased an iexos-100 as an upgrade to her little star adventurer mini (and largely out of complete laziness since she just wanted the goto to not have to go out into the cold to reposition for her next photo!) but we had no time to be able to order the official azimuth adjuster and since we have a polemaster to get PA I wanted it to be finer controlled than swiveling the whole mount around on the base by hand.

So I noticed there was an M8 grub screw in the tripod on the base and I figured if I lined up the part that stick out to support the Alt adjustment with that and attach a frame around it I could then use a couple of machine screws to pivot against that.  hour or so later this is what I came up with



basically it's two pieces of corner brace trimmed to length and welded together and then welded to a piece of slotted angle iron with an M8 machine screw replacing the grub screw.  a couple of nuts welded to the frame with M6 machine screws to act as adjusters and 3d printed knobs.

Now I have a welder and 3D printer to work with but it would have been possible to do this using nuts or rivets to hold it together and captive nuts for the adjusters and just use the machine screws directly or you can buy m6 thumbscrews from places like amazon.

The slot at the bottom, btw, allows macro adjustment just in case there isn't enough micro adjustment available.

It worked surprisingly well and allowed us to get pretty tight PA so I thought it might be useful to anyone else in a similar position.  looks a bit rickity and my welding could have been neater but overall it worked for a materials cost of less that 10 GBP.

I'll definitely take a look at this. I just ordered my EXOS2 today, so next week I'll be able to test against the iEXOS-100, but also the EXOS2 board.
