  1. The handbox on my HEQ5 has died. Mount works on eqmod but I don,t. So looking for a replacement hand control. If you have one your not using then I am in the market for one. Thanks Phil
  2. Continuing my theme of imaging with a vintage long fl achro and mirrorless camera combo. Here's my shot from last night. Stack of 100 subs through vintage Towa 339 F15 80mm with Olympus OM D EM1 mirrorless. Each sub ISO200 at 1/200s. PIPP and AS3 then sharpened in Photoshop and a little colour adjustment. Quite pleased with this. It's in colour, Chromatic Aberration quite low because the F15 was collimated well and nicely cooled. Evidence of CA at the limb, (being blown a bit) but the bits that matter are quite good. I reckon there's still some wobbly frames in there, o
  3. 28, sorry Here,s my review whenI got it
  4. Its the Uni with tray, very stable even with an Heq5 and ed127 on top
  5. Your old mount has the plate John
  6. My 1960s Towa as it is now. Scope updated with Craford and extension, (the scope and how I did the mod featured in Astronomy Now in 2010) Sitting atop my Berlebach and recently acquired Vixen GP with drives mount (thanks John) This is my grab and go ish set up, e.g. when I havent got time or cant be doing with setting up the HEQ5 and / or Meade 127edt and goto. Just set up, point at polaris , switch on the drives and away I go cloud permitting
  7. A decent star atlas, I still have my Nortons from the 70s Lidl ironing chair, so I can sit comfortably and observe RA finder, Saves my back and knees Varifocal spectacles, so I can see the stars and then read the star map without changing from distance to reading glasses. Oh the joy of ageing
  8. Wanted, EQ3-2 mount, with or without polar scope, drives or tripod. Cheers Mount now found, admin please remove, thanks
  9. I see they havent changed much. Years ago I bought a CGE mk1 mount, not cheap at all. It had 11 faults, mechanical and electrical. It went back to the supplier twice. The electronics werent well put together, loudy soldering and the cheapest most unreliable connectors they could find. The connectors and wiring were 4 of the faults. Celestron customer service at the time were a waste of time good ole Dave Hinds eventually sorted some of the faults, I sorted the rest.
  10. I fitted one once using a 2" visual back that screwed on to the back of the scope I had to get an adaptor ring I think to convert the thread on the 127 to accept the visual back. It worked well.
  11. Well done another classic brought back to use
  12. If you ever experienced a Celestron CGE mk1 going daft due to mount lead or microswitch problems then the dictionary definition is very apt
  13. I took 40 subs for each on this occassiin, I used to take about 100 but I wanted to check this technique with the live view. You can still stack with undriven, its fiddly but doable. Adjust the moon to be in the centre of the frame each shot. Not the best way, it can give aligning software a headache.
  14. Thats the way I have always checked refractors and the reason I love collimateable cells, these new fangled cnc,d jobbies are ok but push pull screws are tge best. I never collimate an ota with a diagonal in place, I do check after to see what effect the diagonal has tho. Most of the collimation issues I find are with the focusers unless there has been trauma or finger trouble in the cell. I wrote about my experiences some time ago here https://www.google.com/url?q=http://philjay2000.tripod.com/usefulstuff/adventures.pdf&sa=U&ved=2ahUKEwjw2-fF2ZzqAhW1Q0EAHTbIBqMQFjAAegQI
  15. How loose is it? The glass needs to expand and contract so a bit of movement is needed. There is a danger of pinching the objective by overtightening so beware.
  16. Very nice John. I still use my Towa 339 80mm f15 regularly.
  17. The past few nights of the current lunation I have been using the 80mm F15 Towa to relearn lunar imaging. Being away from astro for so long Ive forgotten a lot of stuff so I decided to give this run of clear nights a go with lunar imaging and doing a bit of experimenting with technique and processing. I think I am almost there with this scope. Not sure why but I love the quality of image this achro gives. Yes my 127 APO gives superb almost colour free views but there is just something about a long achro, like vinyl and cd/mpeg, I prefer vinyl. I Using the Olympus OMD EM1 with its 4
  18. Always leave a bit of space. Overgreasing can cause problems. With high speed applications it is very important to avoid overgreasing but with the speeds we operate at its not so much of a problem but is not advisable.
  19. The supplied ep is OK but a quality eyepiece will transform any scope. There are so many to choose from everyone has there own personal preferences if you are looking for decent eps have a look through reviews on here and in the mags and best of all try before you buy if you can
  20. Yes the lock screw stops the tube shifting but the focuser wheels can still be turned, quite normal The second issue is more likely an eyepiece issue.
  21. Just a point on the focusers on these scopes They are good and work well plus they can handle quite a bit of load. However they seem to be shipped in varying degrees of adjustment from super smooth to dog rough. I have 2 of these scopes in binoscope format. One I got was adjusted really well the other was really bad and was advertised as a customer return due to the rough focuser, I got it with a discount due to that. It took me 2 minutes with an alken key and it was as smooth as the other one. So dont despair if your focuser feels rough it just needs a tweak. Quality control sh
  22. Agreed, I was the same with my 50mm refractor in the early sixties, this showed me so much at the time and I was hooked despite terrible CA and bad coma. Advertising is always hype, just take a look at some of the cure-all pilks and potions from yesteryear but now in the consumer age it is used with everything scopes included. I remember some years ago a newbie joined an astro soc I was in and he threw a lot of money into gear but had no experience except from books. One night he was asking for help after setting up his new goto scope, claiming he couldnt see anything it was supposse
  23. I was messing with a few details on the late 60s early 70s Towa 80mm F15 last week having just made some tube ring adaptors for the Towa to fit in ED80 tube rings and I set it all up on my HEQ5 for a quick test. Then realised what a handsome scope it was and that got me reminiscing. I got the scope 10 years ish ago for £60 ish off fleabay, complete with wooden crate, wobbly but elegant mount. I did a bit of resto on it and the mount and got it working and soon realised that the objective on this scope (despite a couple of clamshell chips) was excellent, it was a good planetary, lunar and
