Re: Mach2 transport case?

Sébastien Doré
 

You might want to take a look at mycasebuilder.com to « virtually try » several case brands/models.

They have a tool allowing you to custom design foam inserts based on your own pictures of equipment so you can figure out easily how whatever you plan to store in the selected model will fit or not.

Re: APCC model like Mach2

Ray Gralak
 

Am I correct that this feature is the same functionality Roland used via the keypad on the Mach2 to build a model
only along the path of the target to be imaged? If so that sounds like a big win for mobile imagers like myself.
The implementations are independent of each other, but the concept is similar. APCC's Declination Arc Tracking is an idea I first had over 15 years ago. The feature does not use the typical model that you would find in TPoint or other premium mounts. It uses hybrid modeling: pointing correction is handled with a full-sky model, but tracking rate correction is dealt with via a different mathematical model that is optimized for localized tracking accuracy. The tracking rate modeling accounts for mechanical terms that the full-sky pointing model does not and thus produces higher tracking rate accuracy than a full-sky model.

Re: Pier for 1100GTO #Guiding

Steve C. Mitchell, Sr., O.D.
 

You’ve been given some good points to consider already. But don’t forget about your wall/pier heights ratio. You don’t want your pier to be to short or you’ll lose those sometimes low objects you might want to capture cause you can’t see over the wall. I actually made an adapter to make the mount higher for my existing 12” pier, I had made for my previous “other brand” mount that was of no comparison to my AP1100, so that when parked my new setup clears the rolling roof with about 5” to spare. A little scary the first few times you open or close the roof when the rafters go passing by, but actually a good distance for safety once you get used to it and “know” it’s not going to hit your camera or telrad or whatever sticks up. I can see all the sky I can see at my location with this height.

I have an 1100GTO mount on order and plan to house it in an observatory on permanent pier with imaging in mind.   I own an old AP 8" diameter portable pier.  Would anchoring this in concrete and filling the tube with sand be sufficiently stable or is there clear benefit in purchasing a heavier thicker permanent pier for best performance.  Any thoughts?


Re: Mach2 transport case?

Jeffc
 

Thx Bill. I was also considering the 1615… if anything I heard it is a good case for the AP130GT.

I feel like the “9.4 inch” dimension is a bit short. But I just measured the mount with foam underneath and it looks doable.

The extra space is nice…. I would prefer keeping the contents as light as possible, but a place to stash cables and other small lightweight parts would work.

Thx

Mach2 transport case?

Jeffc
 

(Apologies in advance for the mundane topic... but I just want to check my options before spending the $$...)

What are you using to transport the Mach2?
Caveat:  I don't want to remove the saddle to transport the Mach2 (unless someone can give me a good reason to remove it.)
I do know about the iM2875, but I'm not sure the mount will fit in the iM2875 with the saddle attached.   (more info below on why)

First.. I will note I'm a new Mach2 user since about 2 weeks... and let me say this mount is fantastic... I thought it might be "too big", but it seems to be just the right size... (fwiw, I also use an AP1200, and also an AP1100 for "portable work" as the AP1200 won't fit (easily) in the preferred vehicle i'm currently driving.)

I can see the Mach2 is going to be a great "portable" mount, and not take up a bunch of space in the car.
Plus with the Encoders and no need for PEM I'm finding unguided imaging is a joy...
(Tho, yes, the AP1200 w/ PEM also seems to do fine with unguided imaging.)

Now.. the question..  
I know the Mach2 will fit in the Pelican iM2875 case using the original packing foam (plus a bit more).
However , it seems the RA needs to be "rotated downward" for the mount to fit.
My problem is I have the 10" saddle on the mount and with the current saddle position the DEC cannot rotate "flat" -- the saddle will collide with the altitude knob at my latitude..    
I could move the saddle up a hole, tho the saddle will then stick out a bit further and I'm not sure it will fit in the case.

So.. other than the iM2875 what are you all using to transport your mount?

I'm currently transporting the AP1100 in a 17-gallon "Commander" storage bin from Lowes and it works great for the AP1100 (I have foam in the bottom)... I could repurpose this for the Mach2 easily, but it is overkill and I would really like to free up some space in the car.
The iM2875 looks almost the right size -- except for the saddle issue.
I'm thinking a slightly longer Pelican case with the same depth and possibly narrower width might be more appropriate, but I'll need to do more research / measurements to figure out which case that is.   (Fwiw, i don't need airline transport -- just from the house, to the car, and unpack at the site, and I'm looking to keep the "unpacking" time-efficient.)

thx for any suggestions.

Yes, that would be great. At high magnifications it is required to have additional relative corrections on top of the tracking. Maybe these corrections could even come from a guiding tool (like Firecapture centering a planet).

Your image doesn't have much noise to start with, but DeNoise AI would
have slightly sharpened it and brought out a bit more detail. I've seen
it remove a LOT of noise in some of my images, and it always improves
the details.

It greatly improved my pathetic Mars images last fall.

Topaz Labs also sells Gigapixel AI to resize images, and Sharpen AI to
sharpen them. I have Gigapixel, but don't use it much because it takes a
LONG time. Just reducing a 4500x3500 image to 800x600 takes 10-15
minutes! I suspect it runs faster on "normal" (non-astro) photos.

Sharpen AI appears to be a new product, and I don't know anything more

The pop up warning window may be off your monitor. Do you have a dual monitor setup? Sometimes if you happen to be using only one of the screens in a dual monitor setup, some pop ups won’t show because windows is still trying to place them on the inactive screen. I had that problem in Maxim.
The park features in the driver have always been there and have worked.
Stick with it you will get it figured out😁

Nothing should happen immediately because a popup window should show a warning that you should not use Park 1. Parking won't start unless you accept that window.

If you didn't see that warning window then maybe it popped up in an area of the screen where you didn't notice it, or the park button was not fully clicked.

Re: ISS Tracking with APCC & Horizons plus using handbox buttons ??

Ray Gralak
 

During the tracking I tried to use the hand-paddle buttons to superimpose correction onto
the tracking trying to
keep the ISS in the camera view screen. It somehow worked a bit but I had the feeling that the tracking was
'fighting' me back. Once I pushed a button to move the ISS to the center 'something' pushed it back by a bit
moments later. I got some success by over-compensating and ISS got then back (closer) to center. At one point in
this effort however it got lost outside the view finder screen and never came back.
Horizons continuously slews to new RA/Dec coordinates, so the A-P mount hand controller moves probably won't have much of an effect. The drift could be from changes in the orbit of ISS. In a future version of Horizons, I'll try to work in a way to detect relative moves and add them in.

Hello All,

Alas, a recent ISS passage and the ISS tracking questions pour in. :-)

I guess this is for Ray. Tracking ISS yesterday with APCC / Horizons / AP1200 worked reasonably well.
Video from the AP130 with 2x barlow and Canon T3i
http://skywatcher.space/download/iss_20210316.mp4

During the tracking I tried to use the hand-paddle buttons to superimpose correction onto the tracking trying to
keep the ISS in the camera view screen. It somehow worked a bit but I had the feeling that the tracking was
'fighting' me back. Once I pushed a button to move the ISS to the center 'something' pushed it back by a bit
moments later. I got some success by over-compensating and ISS got then back (closer) to center. At one point in
this effort however it got lost outside the view finder screen and never came back.

Question:


* What is happening there?
* Is it a correct expectation to operate the hand paddle buttons independent from the APCC tracking? (My
thinking is that the APCC uses custom tracking rate which is something different from what the buttons do). Is that
assumption correct?
* Really cool would be to have a USB access to a PC 'gaming' joystick and use that to move the mount. Any
ideas in the AP mount driver to support that?


As always great shout-out to Ray for the excellent work he does!

Cheers,
Gert
