Thinking about getting the ASIair, and wondered if I could power it with a 5V 2.4A battery pack/phone charger.

Already have a LiFePO4 powertank for my mount, and hoping to be totally cordless.

Hi Roth I used the 5v 2.4 a output on my lipo4 and had the low voltage flash up on the asiair app so I now use outxe power bank 5v 3 amp usb out and haven’t had a low voltage warning yet my asiair usb devices are eqmod,2x asi cams,asi filter wheel . Hope that helps

No, see above, and its actually 12.5mm back. 

and you measure from the rear of the corrector not the centre.

Cool makes it a bit easier to figure it out .only prob I have now is all my extenders are 1.25 not 2 inch lol.

So the sensor site 12mm back from the tip of the camera nose (red)

That's what I was led to believe.

I have a MkIII as well. This is an extract for the VIP edition manual as I could not find reference to it in the MkIII manual (probably on line somewhere) but I am sure it is the same for both.

Well I've measured 55mm to the centre of the coma to the sensor, that pic looks like the start of the case of the coma to the sensor.think I will post pic with ruler on it .

Just spoke to the shop where I purchased coma for the correct placement.

Camera ,filter wheel, coma, scope.?

Camera ---------55mm------coma .

Is this right it makes sense and I have managed to achieve this .

Thanks

0Hi all can you cast your eyes over these pier head plates pics and see if theres any potential issues I'm not seeing before I get to far .😬 the top plates has yet to have a centerpiece cut out for the eq5 mount.

Many thanks

Just seen myself bottom plate need a central hole for the eq5 fastener bolt🤯

Busy drilling the plates for mount pier go to get the spirit from shed to clean steel plates and under up finding a visitor😍 love my garden and the wildlife we get .

Just a baby this years

I do love my postman even in his shorts

Just trying to hunt down someone with a drill now the hole cutter £18 but needs 80 rpm not sure I could do that by eye

🤣🤣🤣 metal worker got back to me for price for drilling 13 holes ,u better sit down £168 +vat .

Looks like I'm doing the holes myself then lol

It's sad to hear that there are these unfriendly Astro groups around.   On-line applications have even fallen down in the past in our very friendly society,  but we have a new Chairman who is very pro-active and replies to all prospective applicants personally via E mail and sends a copy of the letter to the rest of the committee, I went back onto the committee this year so we can all see what he is doing and how many new applicants we get.

Shame other societies don't work this way, but it can be hard when people have jobs as well.  Our Chairman is retired and said he couldn't have taken on the job before he retired.   

Apart from starting one up yourself which is a lot of work, I guess SGL is the only alternative, but such a shame.

Sounds like a great club I may have to pop over one day . I'm going to another fairly local club tomorrow 🤞🏻 their a nice bunch ,is their any def no nos that I should be aware of on my first visit ?

So far 3 mtr pipe £10

4 threaded rods 75cm and bolts washers £16 

2x 8mm steel discs £10 awaiting price for drilling holes 

looks like it’s gonna be less than £100 😀

should I run power ?

Hi all so I'm having something similar to the top of this made up should I go for 4 bolts or 3 bolts  ? 8mm steel so it's not going to flex with either of them . Advice please .

Thanks

Contemplating getting the eq5 extender and just cutting a piece out the middle then weld back together £74 , or just build a fixed pier £100-£150 app.

The fitting would be incorrect depending on your mount.
What I have done is made similar for an EQ5 fitting.

Any chance of a pic ?

I cut down a SW standard riser using a friends lathe, reduced to 7" or 170mm
You could perhaps find an engineering shop that would do the same for you.

I did wander if the eq6 extender would work 8 inch .

Hi all

Using a 130pds for imaging pushes the scope back a bit that means it gets close to the pod legs , looking at a extender to raise the scope mount about 4-5 would eleviate this problem unfortunately the eq5 extender is 70 cm. which means u could well need a stall to place scope on .

Has anyone found away or a extender to raise it 10-15 cm only.

I do have a welder mate but this could be a little crude ( hes a banger racer) .

Thanks

It has a 12v 3amp tip positive outlet so will just use that .

Yeah I'm using the 2.1 amp

 If your power is only 2.1 a then this is probably your issue  pi3 needs 2.5 a try a 3amp power supply which I think is

cant say for sure that's the issue you have but I will say that some USB hubs are utter rubbish and some are not.

I must be having a mind melt or something if I used a usb hub how would the asiair control the devices?

As the ASIAIR is basically a Raspberry Pi in fancy clothes, you get similar issues on PI’s when running too much from the USB sockets. It is recommended to use a powered USB hub to connect up if you get this issue. I know i have had it on my Raspberry Pi which I overcame with using a powered USB hub to connect things up to it.

Powered usb hub 🤔 not sure how another usb hub is going to improve low power , usb hub is just a splitter.

Hi Adam will have to try again to pinpoint it ,but that would make sense.

Did it happen when changing filter? The motor for the filter wheel will have a larger current draw then the rest of that put together

Hi all I was out last night my asiair and a few times a little battery sign at the top right of my tablet flashed up, so i presumed I needed a charge so i plugged it in but battery flashed up again ,turns out it is the asiair saying low voltage .

I was running asiair/eq 5 pro mount eqmod/asi120 mini /asi178 mm/filter wheel , powered with a celestron lipo4 with the 5v 2.1 amp usb .

Anyone else had similar issues ? .

Thanks

Looking forward to see your photographs.

To mount the guide scope I do use a steel plate from a housestore. Then a 3d printed bracket to hold the guidescope.

 

Hi all I see a few ppl have what I can only describe as insulated scope and tri pod legs? Is this an attempt to keep dew from forming on the out side? Would very much appreciate an insight 🤨. Thanks

Yeah seen that one 🤓
