Hi guys,

Does anyone know of a way of using 2" filters with a DSLR and standard lens?

As i am wanting to buy some new filters and rather then having to buy clip filters then 2" filters when i upgrade to a colour CMOS i would prefer to buy one set of filter i can use with both.

If that makes sense

1 micron = 1/1000 mm, therefore 5.2microns = 0.0052mm.  22.2/0.0052   and 14.7/0.0052  = sensor size in pixels.

Thank you so much Peter 

I thought it maybe something different like that appreciate the help.

Hi guys 

 I am using the following website so i can work out the image scale in arcsecs per pixel to put into Pixinsight, however I have been looking on the web and can only seem to find it in mm (22.2 x 14.7m)  and a pixel size of 5.2µm.

 Might sound stupid but do I just need to calculate 22.2x5.2 and 14.7x5.2 or is there something more technical involved as there seems to be with cameras sometimes

The biggest hassle is just the setup. As you can imagine, with everything packed in its individual cases it usually takes me about 7 or 8 trips in and out of the house just to get the components out to the yard and 20-30 minutes to get it all hooked up and balanced.

I feel your pain there. takes me a few trips also which is a pain in the Bottom being in a wheelchair...lol

This is the route I took, the Pegasus has a couple of bonuses in that everything plugs in directly. No dew controller box, USB Hub or focus controller to worry about.

Not sure I would be able to afford the V2 with the USB hub etc. But would be nice. 😀

I Constructed my own, using an ABS enclosure, half a Dozen Buck converters, toggle switches,  some 5mm LED indicator lights,  a number of small Aviation grade plus and sockets. I used a Maplin 10Amp 13.8V PSU. 

The Bucks were mounted on a circuit board, and the appropriate output voltages trimmed to suit whatever device I fit to the scope,and ffrd out to the output sockets

My Canon supply is 8.2Volts, Olympus 7.4volt. Atik314L 12Volts, Startech usb hub 5.2 Volt  Dew strap hub 12 volts. Lakeside focuser 12 Volts. Filter Wheel, Usb only.  Not forgetting the EQ6 mount supply . One power cable, to the box input, and one Usb cable to the Startech Hub.        All the supply and Usb cables mirror the movement of the telescope.  The only ones that I need keep an eye on, is the EQ input, and the guide usb.

I think this is a bit beyond what i could do

I am like the look of the Pegasus Powerbox as saves me having to make my own cables etc. i know it more expensive but i guess it saves me screwing anything up.

Can you buy a rigrunner from another supplier? As long as you know what you're doing, 12 V is quite safe. Depending on your setup and budget, you could go for a power box, such as Pegasus Astro or Hitec Astro. Not cheap though. But they allow for a tidy cabling solution. 

I wouldn't say i 100% know what i am doing, but also don't think i am a total idiot which is why i thought using something like https://www.amazon.co.uk/100-240V-Adapter-Converter-Transformer-5-5x2-5mm/dp/B0787CPCTW would be fine once i have cut off the end and added the Anderson PowerPole connectors. 
Look at the options you have listed i would still need a 12v DC input and that is what has got me all confused at the moment. 

Hi guys

I am looking for some advice/tips for power cable management. I was going to use a rigrunner velcroid to the side of my mount so I could just have one power cable and a Powered USB hub for all other devices so in total only 2 cables to my mount.

However, after contacting the company for the rigrunner they said they wouldn’t sell me one as I was going to be running from the mains and it is a 12V DC input. I did explain that I would be using a 240V to 12V DC adaptor, but they said this wouldn’t be suitable.

So, I am now at a bit of a loss what to do about the cable management. Any help or advise would be great full.

Just to let you know I am in a wheelchair so using things like deep cycle batteries is a bit of a no go due to the weight

Thank you very much guys appreciated 

I have a Sky-Watcher .85x Reducer/Flattener for ED80, I can see that I have to screw it direct to the drawtube (shame there isn’t a quicker/safer way) but I can’t figure out how to attach it to my Canon 1100d do I nedd a different adaptor as the one I currently use to attach my camera to my 2” tube extension doesn’t seem to fit.

Also I have read somewhere the you have to have to correct spacing between the camera and Reducer/Flattener in order to have round stars how do you do this?

Hey Guys 

I am looking to sorting my cable management out this summer while the weather is nice and not able to do much imaging. i am looking to go with a powered USB hub and ad rigrunner for power management. 

I have looked around and and i am unable to find anything to say if i can wire a rigrunner to use direct from the mains power supply as i do not use a battery pack due to them being to heavy for me to move as i am in a wheelchair. 

Does anyone know if they can be used in this way and any other advise on cable management would be most appreciated.
