  1. Past hour
  2. I use Velcro straps. Picture attached. You can see some around the handle beneath the guide scope that tidy up the dew straps and behind the main camera. The camera to computer leads are strapped together in a ‘loom’. Makes it easier to adjust which wires go where compared to a spiral wrap and makes tidying up at the end of a session easier dealing with ‘one’ wire. https://www.amazon.co.uk/Grapelet-Black-Adjustable-Strap-Reusable/dp/B01M3SMRBO/ref=asc_df_B01M3SMRBO/?tag=googshopuk-21&linkCode=df0&hvadid=223170773229&hvpos=1o5&hvnetw=g&hvrand=6522590945153768859&hvpone=&hvptwo=&hvqmt=&hvdev=t&hvdvcmdl=&hvlocint=&hvlocphy=9045049&hvtargid=pla-421533026280&psc=1 John
  3. This stuff is nice to work with - it's like spiral wrap, but split like a zipper. Comes with a tool to zip cables in easily. Much easier to add and remove from the bundle and unwinding spiral wrap. You can break cables out wherever you need along its length 28mm Cable Tidy c/w Applicator - Black
  4. Sounds like a good time to be imaging Jupiter. Not so fortunate for those of us well to the north James
  5. Cracking little bino! This is the one I fund-raised for a year ago (FLO donated six ); altogether I have a dozen that I use for outreach; ideal for youngsters. All arrived in, and remain in, collimation. A waterproof bino of this optical quality is a steal at this new price.
  6. Spiral wrap seems to be very popular for keeping them all together and out of the way, but even then I guess you'll have to separate them somewhere. James
  7. Steve - They are 100160, 100583, and 082293. I strongly recommend The Cambridge Double Star Atlas - it gives these numbers. I then put them into the handset and reach the targets. As I said, if they are not in the HS, I aim for something close, then "hop". The three I saw are all good to view - close (at different mags), with the fainter member at different orientations - very nice. I was pleased indeed to see the last two, as my mag only goes to x160 (until I get a focal extender on my birthday!), and I am sure I would not have seen clear splits had I been using the Cat or Dob, since they are not as sharp as the frac. Have fun! Doug.
  8. Just seen this on the Spaceweather site, very intruiging and something for both observers and imagers alike to have a look at in the coming days/weeks/months..... https://spaceweatherarchive.com/2019/05/20/is-the-great-red-spot-unraveling/
  9. Hi Johannes I’m using a SW 250px that I purchased in 2010. Excuse the mess of cables. Just a temporary setup.
  10. I've used TS many times and they are very good in my experience. It takes a few days longer to get the goods but they have been highly reliable in my experience. I would be tempted by this one: https://www.teleskop-express.de/shop/product_info.php/info/p9868_TS-Optics-PhotoLine-102mm-f-7-FPL-53-Doublet-Apo-with-2-5--Focuser.html Stu
  11. Hi all please tell me I’m not the only one who gets freaked out with the messy cables . Any ideas on tidying them up ,Eq5 pro goto din cables are super stiff and short 2 camera cables ( not cooled(yet)) dew heater running to ASIair and then to tri-pod power EQ mod . 9 cables 3 cam/cam/dew strap which need to pass the axis of the mount if asi box mount on stand or 3 eq mod/dew strap/ power if asi box on the scope + the 2 din cables . Any pics with ideas most appreciated.
  12. Alan, Good analysis! I think you are spot on and the voltage measurements show that there is a current limiting resistor in series with the photodiode. Hopefully, Peter's tests will confirm that the relay will operate as required with the IN+ terminal connected directly to the positive rail when the IN- terminal is shorted to ground. It's a nice idea of yours to order a relay board yourself. They do seem useful things to have around. Regards, Hugh
  13. Don't worry Gav, PM sent to Jonk with link to Dropbox files. William Jon. Have sent you a Dropbox link via PM William.
  14. Hello and a warm welcome to the SGL.
  15. Many ED refractors in the range between 80mm and 130mm from TS Optics, Altair, Astro-Tech and Stellavue share the same origin (e.g. 102 f/7 doublet, 115 f/7 triplet, 125 f/7.8 doublet, etc.). The only difference you may find sometimes is the focuser. If I were to pick one of these scopes, I'd buy from Altair as they are based in UK so the shipping cost and the risk of damage during transportation would be the lowest. WO scopes are mostly made by Longpern. There have been a few models with premium optics made by LZOS (FLT123) and TEC (early production FLT110), but otherwise the optical quality is comparable to the above four rebranders. I certainly wouldn't pay extra £400 for the fancy colour paint of the WO scopes when they are new. However in the used market WO are quite competitive.
  16. One of my favourite galaxies and you have it tight focus with good guiding. It just needs more. Don't they all! Olly
  17. Today
  18. Doug, Thanks for posting. Can you tell me the SAO numbers of these doubles. I have my Altair ED 80 on a SW star discovery mount and much prefer to find by SAO number. Id like to check these ones out. Steve
  19. Cheers Gav, that'll be great. I haven't done anything for months due to moving house, so the new to me qsi is still in its box! This time of year is good to get things ready for the new season, and I always look forwards to the perseids in August!
  20. I'm in the OAG category, and have fitted the Orion TOAG. I think I'm going to have to inject a shim of somekind to tighten up the drawtube. Let's see how this goes. It's a shame the focuser replacement isn't a simple process.
  21. Steve this all sounds ominous. Can you please clarify if there is a concern over safety.
  22. Hello Chris - as Helen mentioned I have the Heritage 130P which I use as a quick grab and go but also I take it to outreach events with my Astro Society. I have made a few changes to the scope which you can see on the photos. I have changed the secondary screws to 'Bob Knobs'. I have drilled the main OTA to fit a dovetail so I can use a 9x50 finderscope. Finally, I made a shroud out of neoprene which is secured by velcro. The two photos show it fitted on various mounts - a Skywatcher AZ5 and a standard photo tripod with a geared head for travel.
  23. Reading the first link, the prospect of upgrading the focuser sounds very scary. Appreciate you sharing this, it has tempered my aspirations. Luckily the scope I have is reasonably well collimated - I think. When I rotate the Hotech SCA in the barrel, it moves suggesting that either the Hotech is off center or there's something off about the drawtube hole. Nonetheless, trying to KISS atm.
  24. I'm planning an upgrade from my current mono CCD. Apparently a lot of people go the CMOS way these days, so I consider whether I should follow the trend or stick with the CCD. I'm primarily interested in imaging faint far-away galaxies. I noted the new CMOS cameras from SX, but one thing worries me: They are 12 bit whereas CCD cameras are 16 bit. I know that you gain contrast when processing the images, so does it matter?
