    Stargazing Live Stacking

    The only ref I heard was a comment of Chris Linott saying that the software used was only used for individual stars only and never on wide field (or something similar)

    Does anybody know what software they are using for the orion stacked image

    Home insurance

    Yes I have when my garage caught fire a few years back. The insurance company (MoreThan) would cover the costs of the damage however they would only give you the funds via pre-paid cards that could be used where they say so. For me I was not able to replace any of my Astro kit because I could only spend the £12000 at Homebase and Argos. For a pre-payment card where I could spend where I like was only given on items that where registered on the insurance policy and was over a £1000 Always read the small print.

    Raspberry PI and Stellarium DIY finder

    What EQ mount do you have?

    First guide scope and guide camera

    Get a cheap QHY5 and a SW9x50 Finder to create a FinderGuider. You can get the bits from Modern Astronomy. Probably is the cheapest option and works great with PHD/ASCOM I have had NO issues with mine

    USB hubs

    It works as you are using very power power devices on the max recommend usb cable length. All within spec.

    USB hubs

    One other thing I have noticed is that some USB hubs the usb sockets are very flimsy and the slightest touch can disconnect the plug from the hub. I would not recommend this type http://www.ebay.co.uk/itm/New-High-Speed-2-0-Mini-USB-10-Port-HUB-with-Power-Adapter-Black-UK-/111317525419?pt=UK_Computing_USB_Cables&hash=item19eb0aa3ab I brought 2 about 18 months back and they are useless. You need to look for a hub where the usb plug firmly attached to the socket when plugged in. For my new custom power pack I am building in the usb by using some other types of USB hubs which has tight fittings. http://www.ebay.co.uk/itm/Mini-High-Speed-USB-2-0-4-Port-HUB-Splitter-Cable-Adapter-for-Laptop-PC-Notebook-/261668933267?pt=UK_Computing_USB_Cables&hash=item3cecaf0e93 These are the one used in the YesYes SPC900 Mod http://stargazerslounge.com/topic/109153-spc900-lxmod-yesyes-style/#entry1080810 All I need to do is add my own 5v supply from one of the LM2596 convertors to get it powered.

    Any Electrical Boffins - Questions about Bucks, Fuse etc

    True, but if necessary I can just use a red torch to see the dials, or backlit the meter with a red led. Anyway, I am slowly working through my list of things and it is surprising how things add up.

    I just prefer the style of old analogue needle meters.

    Thanks NEM, With regards to the LED, do you means something like this.... ---- LED ----Resistor ----- Negative Terminal (Or should the Resistor come before the LED 12v ------ SWITCH ---| ---- Load ---- Negative Terminal

    Thanks Tinker, but I am not an electrronic person so these circuit diagrams are quite above my understanding.
  12. Hello, I am reworking my custom power pack as I had a few issues with it and would like to ask some questions and hopefully an Electrical Boffin can reply. 1) I am using a LM2596 Buck StepDown (off ebay) to step down from 12v to 7.5 to power my Canon 1100D. I want to add a fuse to the powered item (Canon 1100D). Where would the fuse go to provide the best protection? example 1: 12V Battery ------ 2A fuse ------ LM2596 ------ 5V Canon 1100D or example 2: 12V Battery ------ LM2596 ------ 2A fuse ------ 5V Canon 1100D or example 3: 12V Battery------ 2A fuse ------LM2596 ------ 2A fuse ------ 5V Canon 1100D 2) I want to add an Analogue Ammeter to my setup. Previously I been told to add the ammeter between the Battery Negative Terminal and the Negative power return, however I have see a few youtube video where they are saying it goes between the Battery Positive Terminal and the Positive power lead into the circuit. Which is the correct way. I will be adding an Ammeter onto the mount to monitor the amps (as I have been recommended) and I also want to put on to show the entire amps my custom power box is using in total. 3) If I have the following simple circuit how can I get an LED to come on when there is power to indicate that the circuit is live. example 12V Battery -----SWITCH ----- LM2596 ----- LED ----- Powered On Item Previoulsy when I have tried to put an LED into a circuit there is not enough volts/amps to power the item, how do I get round this? Thanks

    Imaging Software

    To get better long exposures you will need tracking, what mount do you have.

    PHD Details

    Try PHD2, a lot more going on there at the moment and a much superior package. http://adgsoftware.com/phd2/snapshots.html On my rig (QHY5 FinderGuider) I pulse and it does take a while sometime to calibrate. I just keep adjusting my Calibration steps (Currently at 2850) to compensate. Never used ST4.

    Exoplanets and DSLR

    Hello, I am surprised no one has posted this yet. How to prove exoplants exist. http://spectrum.ieee.org/geek-life/hands-on/diy-exoplanet-detector The article is mostly about building a barn door and one one tiny reference to how to verify the exoplanet by using Microsoft Excel to make differential-photometry calculations. Would love to see that spread sheet to see the calculations behind it all.
