  3. Hi mike, i am on holiday at the moment but would be happy to send you a copy of the software. It used iokit for talking to the hid but you could use Libusb to do the same job on the pi. I used jet brains dotpeek to convert the hitec Astro dll that comes with their software. It gave me the appropriate bytes to send to the device to control it. i am back at home in February so could send you the source code then. Cheers John
  4. Many Thanks Tim, When I looked through it visually, It always gave good clear views. And for imaging they give fantastic flat images. And a view down the scope not in the original images John

It also has an Off axis guiding port to give everything required for imaging in a single package.

  7. Blue one sold - Just the other one left now
  8. Hi All, Going through my Astro gear I have found that I have two HitecAstro USB EQDir cables for an EQ 6 mount (Not quite sure how that happened). It has a Hitecastro connector at one end and a D9 connector at the other for the mount. From looking at the Device descriptor in USB Prober. They are based on the Prolific Chipset for those who look at this spec £15 each posted Cheers John Edit - Just one left now
  9. Fantastic. Nice to see it in its new home. Hope you enjoy it as much as I did John
  10. Hi All, With work demands and just being generally busy at the moment, I’m not able to find the time to do any astro-photography. So I have decided to sell my Astro gear as its not getting the use that it deserves. The items for sale combined made up a reasonably competent observatory. Its sad to let them go, but I would rather that someone get better use out of them that I have been over the past year or so. I’ll put a link to the sellers website so you can get the specs for each item where possible. Skywatcher MN190 Maksutov Newtonian telescope - £625 (Reduced Price) https://www.firstlightoptics.com/maksutov-newtonian/skywatcher-explorer-190mn-ds-pro-mak-newt-astrograph.html This is a lovely flat field telescope and is ideal for imaging as well as visual use. It is the newer variant so it has a twin speed focuser. Also included with this are the original right angle view finder, A dew shield and a Bahtinov Mask. It is also in its original packaging for transport. The mounting bar has some marks where it has been used to attach it to the mount but these are only cosmetic. Again postage might be expensive for an item of this size so probably best delivered/ Meet up/pick up in the Cambs, Herts, Suffolk, Norfolk area. Hitech Astro Mount Hub Pro - £175 - SOLD https://www.modernastronomy.com/shop/accessories/mount-accessories/hitecastro-mount-hub-pro/ This is the original version of Hitech’s Mount hub pro. with the six port USB hub. 4 Dew heater outputs, 12V DC power outlets, and a focuser controller. It also comes with the additional controller to manually drive the focuser and a couple of made up power leads to connect things up. It had its firmware updated by Hitech astro a year or so ago so that it works correctly when plugged in/out of USB. I have a whole load of smaller items so will start another thread when I have sorted them all out. If there are any questions or you want any more info please feel free to send me a PM. Cheers John
  11. Another option is to go for the chemfix - chembolts. https://www.sealantsonline.co.uk/ProductGrp/004400510001 Just Drill a hole into the concrete and resin fix them in to get a nice flush fit. Then you just bolt into them from the top with standard bolts. The advantage is that if you wish to remove your pier, you don't get any nasty threaded rods sticking out of the ground. Councils use them to fix bollards and the like. Hope this helps John
  12. Hi Rob, I have had a look at the way that the software works for the HitecAstroDC and DC2. Unfortunately it appears to have a different control protocol so I don't think that I will be able to mod my program to suit your needs. I have sent you a PM with details of the VID and PID values that you will require to modify the INDI driver .rules file. That combined with Information you obtained from the INDI team should enable you to get the Focus DC2 working with your system. Cheers John Edit: Looking at the GitHub repo for INDI, It looks like Andy Kirkham has updated the source so that it will work with the FocuserDC2 as the new VID/PID is in the source. Downloading the latest of INDI will probably sort your problem.
  13. Hi Paul, I went for the these http://www.fhbrundle.co.uk/products/0586604000__80mm_Dia_V_Groove_Wheel_One_Ball_Bearing_Internal_Support They fit inside the toprail so give a nice low profile. The first two pics are from inside the obsy and the last one was before I fitted the roof. HTH John
  14. One thing i noticed when I wrote my Mac version of the MHP software was that if I sent a focuser command, whilst the motors were moving, you could not perform any other commands. As there is no feedback from the MHP, you did not know that the command had failed. I guess it will be the same for the windows command too Cheers John
  15. Hi Andy, I got mine from JTW Astronomy via Amazon. https://www.amazon.co.uk/Skywatcher-EQ6-Mount-Pier-Adapter/dp/B00ZMDGTDC They are currently out of stock but you may be able to contact them via their website http://www.jtwastronomy.com There are other suppliers too http://www.billetparts.co.uk/catalog/pier-adapter-p-136.html http://www.green-witch.com/altair-astro-multi-mount-pier-adaptor-2679-p.asp The other option is to go DIY - I remember someone on here using a brake disk with great success. John
  16. Hi Andy, Here are some pictures of the pier I had made. The pier itself is 1.2m high and has an 8" plate on the top and a 10" base plate. The plate is 10mm thick top and bottom and the steel tube is 6mm thick. I had an owl hole fitted so I could get access to under the top plate so i could bolt down the Mount. Then had it sprayed at a local car repair place and they also sprayed wax oil on the inside to prevent rusting. I bolted it down using chem-bolts and roughly aligned it so that it was within the adjustment of the NEQ6 and then fine tuned the PA afterwards. HTH John
  17. Well back in 2014, I said that I wanted to put together a wide-field rig for my QSI 683WSG and I have eventually managed to get started on it. :-) The WSG variant of the QSI 683 has an inbuilt back focus such that canon lenses just don't quite work. (They fit OK on the WS variant with an adapter) To get over this problem I have used a Pentax 6x7 medium format lens that has an back focus register of 84.9mm. QSI used to do a 6x7 lens adapter for the camera but it was about £225!!! but have since stopped making them. I have taken a Canon - 6x7 Lens adapter, bought on eBay 3 years ago, and machined off the canon adapter at the back to give the correct back focus distance. Then drilled 4x 3.2mm holes straight through the back of the adapter into the central lens area. From the other side , I then drilled 5.6mm holes back until about 3mm from the camera end to give a shoulder for the screws used to fix it to the camera. I also needed to cut a step off the top of the adapter so that it didn't foul on the guiding head. This then made it look like the QSI adapter. To attach the adapter, I removed the T Mount-attachmenton the camera and then fitted my custom adapter in its place. To mount it all together and to give some support, I bought a Gemstone Lens support and Attached it to a Mini Dovetail bar. Original QSI Adapter: https://www.optcorp.com/qs-ad5-p67-wsg-pentax-6x7-lens-adapter.html Gemtune Lens Support: https://www.amazon.co.uk/dp/B00VE0KH2Q/ref=pe_385721_51767431_TE_dp_1 Now it is assembled, I still need to check the measurements to ensure that the register distance is spot on and to do a test run (Awaiting a clear(ish) night). I will probably fit a velcro strap to just secure the lens in place and need to get a Teleskop-express micro-focuser large enough for the 6x7 Lens But for now here are some pictures of it all together Cheers John
  18. Hi Dan, The Twin quasar is an amazing object. The gravity lens shows you two images of the same object and that the light from A gets here 417 days before the light from B. Heres a picture that I took back in 2012 with a canon camera (the two 'dots' in the right) It also easy to find as NGC3079 points right at it. John
  19. very nice image - good star colours and the M81 showing some nice dust lanes John
  20. Great result - especially using your guide cam. Look forward to seeing your images when you get your new camera John
