Alien 13

Some power banks will shut down if there is not enough standing current, the ones I have (pound/discount shop) work fine with my EQ3-2 but I expect the intelligent ones might be the problem. There is a fix if you are electronically minded either by adding a small constant load or switching one in every few seconds, this blog provides some details https://www.dorkbotpdx.org/blog/paul/battery_pack_load Alan P.S. I have to say that the power to weight ratio of these devices means I use them for most everything now, even powering my Canon DSLR and emergency lights, oh and any projects I have on the go.

The wedge needs to be screwed directly to the tripod i.e. remove the pan/tilt head.. Alan

The "unusual telescopes" looks good, like the way they keep their hats on Alan

Impressive, you will learn lots from this project.. Alan

I use one of these for my scope https://www.firstlightoptics.com/adapters/skywatcher-2-inch-t-adapter.html but if your focusser draw tube is threaded then simple T tubes will work https://www.firstlightoptics.com/adapters/t2-extension-tube-set.html the diagonal takes up about 2 inches of back focus. Alan

Great project, well done.. Alan

It can do if you go to extremes but normally you step down to something like f/4 which often seems like the "sweet spot", a step down filter ring is often an easy solution, this is an example https://www.ebay.co.uk/i/281824071625?chn=ps&dispItem=1&adgroupid=49523053841&rlsatarget=pla-352776031395&abcId=1128956&adtype=pla&merchantid=113698737&poi=&googleloc=1006867&device=c&campaignid=857339205&crdt=0 You would need to calculate the size required for your lens filter thread and required f/stop.

Star adventurer challenge, any subject and any scope/camera/lens combo that will fit. Alan

I cant understand why anyone is crouching down looking through any polarscope, there have been lots of threads mentioning the use of a camera right angled viewfinder its such a simple solution. Alan

I dont have this issue with my 80D which has a similar sensor but have no idea about the 750D, I did find this site http://www.photonstophotos.net/Charts/RN_ADU.htm which would suggest that the 1200D is actually a very good performer with a lower read noise than a 700D Alan

The sensor is different and the processor is Digic 6 vs Digic 4 so noise performance should be better, you also have more features and wi fi connectivity which I find very useful if I want to shoot and view from indoors Alan

The 600D is undoubtedly a better package than the 1200D but from the responses is not a worthwhile upgrade, something like the 700 or 750D would be a different thing though. Alan

I love mine Alan

I do like this mount, I can have my DSLR and lens on it and from the comfort on my sofa be able to find/focus and image either the moon or any other object, I would disable tracking and just use the 400 rule for wide shots or track objects like the moon with the 400 lens. Alan

If the Universe is flatter than a flat thing then any extra dimensions that make the earth a sphere are just an illusion Alan

I have been thinking more about this mount and using it in combination with a DSLR and wide lens or even the 70-200 to take 10 -20 second exposures of Comets etc. Alan

Thanks very much for that, found it now Alan

I couldn't find the app on android, whats it called? Alan

Thats good to know. Alan

Its an unfortunate result of the laws of Physics with tripods that you cant have all three, for me weight is the most important provided some of the stability can be recovered by going low, can the height be adjusted by any amount? Alan

You have to use a std USB lead and cut one end off and solder a suitable connector to it. Think its a 5 mm x 2.1 mm or 2,5 mm connector, the red and black wires in the usb lead will be plus and minus. Alan

To get back on topic, this new mount is still the best option I have seen offering wi fi, there are so few around and I have looked... Alan

My EQ3-2 will run for for weeks off the 11000 mAH one, the Canon about 4-6 hrs. Alan

They can power the SA the EQ3 and EQ5 with standard motors and even my Canon with a diy adapter. Alan

I was thinking about using it for normal photography (my camera is fully wi fi controllable) so the offset might be an issue for panoramas etc. Alan
