  1. I’m considering purchasing a telescope for my 5 year old grand nephew. He was born with Spina Bifida, is often in a wheelchair but can standup. Right now he calls most planets Mars but with time I think he would improve. Due to his physical issues attaching a cellphone or an usb mount to hook it to a computer will be necessary. I need something simple to set up and adjust, so he won’t get bored waiting, and make it easier for his parents. The cellphone mount is necessary due to uncontrollable head and hand/arm movements. I want to encourage him to investigate things he shows interest in pursuing. My dilemma is I’m on disability and need to keep the price ~ $200-150. I know that’s not a lot of money, but to invest more at this time would be pointless. I’d like to get the most bang for my buck and realize the cellphone/computer mount would be and extra expense. His parents also own a DSLR, so if there are mounts for those that’s also an option. If there are options slightly above that price range that are significantly better for the price, please point those out as well because I could always get my brother to chip in to split the cost ?. Thank you in advance for any and all advice! Mick
  2. I am ready to purchase my laptop, it will be an Intel core i7 with all the trimmings, my questions is regarding drive space and typical imaging file size output. Many new computers have solid state hard drives, they are much faster but space is sacrificed as even the upper end laptops have 256gb SS drives. Somehow I feel that a 256gb drive will be low for an imaging laptop, I know I can add an external drive but I want to avoid carrying anything else. Maybe I should opt out of solid state and instead get one with a 1Tb standard drive?. Or, am I wrong, and 256gb SS drive will do the trick? I have no idea what a decent range is for typical nights imaging or solar imaging sessions.
  3. Perhaps the most interesting and curious archaeological object related to astronomy is the Antikythera mechanism. It was discovered a little over 100 years ago in 2nd century B.C. shipwreck near the Greek island of Antikythera and is now in the National Archaeological Museum in Athens. After more than 2,000 years on the seabed, it is obviously in poor condition and badly damaged. However a variety of complex imaging techniques have begun to unravel its secrets. It is a very sophisticated mechanical "computer" to calculate the cycles of the Solar System. For an overview, see: https://en.wikipedia.org/wiki/Antikythera_mechanism And for more detail: http://www.antikythera-mechanism.gr/ For me, the most fascinating aspect of this unique surviving object is that presumably it was not unique in its day. It reveals a level of scientific knowledge and technology which may have been available at least in the eastern Mediterranean.
  4. Before I go and Purchase some new USB Leads does anybody have any recommendations where to buy Reliable and quality USB leads. As i had 2 USB cables go faulty on me last night for both cameras which wasted a rare and lovely clear night's imaging session. And i do not want to have keep redoing the wire harness so stressing the other leads e.c.t.
  5. Hi there folks, at the moment I'm primarily a traditional, through the eyepiece observer, however I'm putting together a list of components/software that I will need going forward as I venture into the realm of EAA. Primary consideration for my EAA platform is that it be easily transportable with as small an on-site footprint as possible. My thought is that I want to be able to control everything remotely over WiFi, I have an abhorrence for spaghetti cabling, so want to be able to keep this situation down to a minimum. To this end I have put together a list of components which I think will facilitate the sort of observing platform that I am aiming for: Item 1 - Polemaster from QHY and associated control software. I have both Alt-Az and Equatorial setups, however I see the equatorial as being the primary mount for EAA, hence the investment in Polemaster. The EQ is a Vixen SXW and the Alt-Az and Altair Astro Sabre. Item 2 - Small footprint CCD/CMOS Astro-Camera (I'm thinking along the lines of the SX Ultrastar), and associate control software. Item 3 - Guide camera (Although this may not be an immediate requirement bearing in mind my primary goal is near real-time observing rather than traditional CCD astro-photography). Thinking perhaps the Altair Astro GPCAM, or perhaps an older SX Lodestar. Associated software perhaps PHD2, what alternatives are there? Item 4 - Computer stick or very small footprint PC capable of being fixed to either the mount or OTA, without seriously adverse weight impact. The device needs to have integrated WiFi capability and the ability to interface to guide camera, primary camera and Polemaster. Needs to be run from 12V DC supply. Item 5 - Apple iPad (already acquired). Item 4 poses the question, does such a device exists that will enable simultaneous connectivity to all three devices? Immediately people may think of alternatives such as the Mallincam line of products, Revolution Imager etc... however I want to try and steer clear of the older analogue technology. Is the suggested approach realistic, in getting me to where I want to be, if not, are there alternative ways of achieving the same goal? Would appreciate the forum’s thoughts, and in particular any insight from fellow forum members who may have taken a similar approach. Kind Regards Paul J.
  6. To have all the needed equipment easy to use and functional is important out there in the dark. I have earlier built an astroserver and put it in a box with wheels together with a car battery. That was in mind of to be portable. The astroserver work as a standalone unit and I control it remotly. As I see it it's a lot of advantages to have it like that when doing astrophotography. You can read about the details here: http://astrofriend.eu/astronomy/projects/project-astro-server-and-powerunit/project-astro-server-and-powerunit.html But now when I'm ready to start to use my new observatory there is some different needs that the astroserver and it's power unit must be corrected for. My old astroserver works very well so I will keep most of the parts but remove the battery from it and have the battery stationary in the observatory. There are some other details that I have corrected too. As usual I have taken some photos and written text to it so you can follow my work: http://astrofriend.eu/astronomy/projects/project-astro-server-and-powerunit/project-astro-server-and-powerunit-ver2.html I hope you find something you can use, or at least one little small detail. /Lars
  7. Hey guys I am curious. I'm about to get myself some auto-guiding kit however I don't have a laptop to run the Backyard EOS or the auto-guiding software. I know a lot of people like to run cables to the inside of theri home and hook up tech there but where the fun in that?! Due to the freezing cold temperatures and dew this time of year, what laptops (if used outside) do you guys rock with and if you do, how do they handle with the cold temperatures. Cheers for any advice. - Tom
