  1. Thanks for this, David, this was very informative for someone who is not particularly au fait with electrics (I'm now 20 and kicking myself for not paying attention in my physics lessons 4 years ago). The power cable is centre positive and I've got a Masterplug RCD adapter, so if all goes to plan this should solve my power supply woes. Kind regards, Ben.
  2. I have been using a skywatcher power tank which just seems to fail every time. Fully charged and I’m lucky to get three hours out of it (it’s been properly maintained and is relatively new which is disappointing). Will this combination of cable and extension work for my HEQ5? Using a mains port would save me some headaches.
  3. Forgive me if I’m being dim but I don’t see how moving the counterweight 6 inches towards the already heavier side of the rig would make it any better? Never experienced that before, I always have it slightly east heavy but never by a distinct amount.
  4. You could try leaving half the counterweight bar not fully out - this might add a few hundred grams to the scope side.
  5. This is mine. I’m pretty sure it’s a way off perfect balance but it guides reasonably well at 0.9-1.2rms roughly. I’m gonna get a bulkier guide scope just to add some weight.
  6. Finally got round to getting a decent scope and mount, the Evostar 72ed and HEQ5 pro. Taken from a Bortle 7 zone 01/09/19. 55 x 180s (10 Darks/20 bias/Dithered) ISO800 Canon 700Da Skywatcher Evostar 72ED Skytech CLS EOS clip HEQ5 Pro Guided and dithered with ZWO ASIair guiding bundle
  7. Thanks! 55 x 180s subs, 10 darks, 20 bias and dithered every 4 subs.

  8. Thanks for your reply, but I think you’ve misunderstood me. I was worried about the counterweight being too heavy and overpowering the scope. Anyway, I’ve answered my own question with a night under the stars
  9. Evening folks, My new HEQ5 pro is being delivered next week, I’ll be using it with an Evostar 72ed, OVL flattener and canon 700d. Not sure of the weight of the OVL but I reckon it’s 500g max, total weight on the mount will be (estimated) 3kg or so (possibly less depending on the OVL weight). Will I have issues balancing this with the HEQ5’s 5.1kg counterweight? If so, can anyone recommend an alternative counterweight that won’t break the bank? I’ve looked at EQ3-2 counterweights just in case but I’m not sure if these will fit an HEQ5 pro. Thanks, Ben.
  10. Going to be getting my 700d modified soon, and I've got two options. (I'll be using it for daytime and astro, this is the important bit). Option 1 - Get my 700d Baader modded and to retain autofocus (it's my understanding that the Baader bcf will also act as a UV/IR cut filter, but please correct me if I'm wrong) and then purchase a Skytech cls filter (I live in a Bortle 6). Total cost £195. Option 2 - Get my 700d modded, without the Baader filter but with a re-shimmed sensor to retain autofocus, and then purchase a Skytech cls-ccd for the necessary UV/IR filter. Total cost £165. Now, I am your average skint student, so those extra few quid are reasonably important, but if the more expensive option will yield better results I can stretch to that amount. I'm not fussed about colour balancing, I've been dealing with RAW colours for years so that's not an issue. All I need to know is which will be the better option, which will give better star colour or better contrast etc etc, or is it just six and two threes? Thanks.
