  1. I’ll certainly be checking it out before I use it again, along with updating the firmware. Thanks.
  2. Must admit, I last updated the firmware towards the end of last year. I’ll get onto that as I should’ve been on top of it anyway. Thanks.
  3. Ah, maybe, although I can’t recall when the SkyPortal app last updated. Sounds plausible.
  4. Just a bit! Using SkyPortal on my iPad the date, time and location are always current, so maybe not that unless they can clash somehow?
  5. I’ve been using my 8’ Edge HD on an Evolution mount for a couple of years now and I added a wedge to it a few months back. Using SkyPortal with StarSense I’ve never really had any major issues getting it aligned. Last night I was setting up to photograph Mars and went through my normal procedure. StarSense took its images but, after confirming success with the third plate, instead of just winding up a bit and parking it proceeded to pitch the ota towards the north well below the horizon. Fortunately nothing snagged. I skipped the ASPA and instructed it to goto Mars and was surprised to find it was spot on (better than usual actually). Anyone any ideas why it took that nose dive? Thanks.
  6. Thanks for the advice Ray, I’ll check those out Looking at the ota I see there are several screw heads. Is there a way to identify which are safe to use for attachments? Wouldn’t want to undo anything critical by mistake
  7. Hi All Depending on the piggy bank I’m thinking of getting a Skywatcher Evostar 72ED primarily for photography. However, it strikes me that I might also be able to press it into use as a guide scope on my 8” Celestron Edge HD. I’d be grateful for any advice on how exactly I could attach it to the ota please? I already have a StarSense camera and a finder-scope attached. Thanks
  8. Ah! That’s very useful, thanks Presumably the hub doesn’t have to be anything fancy? Would something like this be OK? https://www.amazon.co.uk/Atolla-Powered-Splitter-Switches-Charging/dp/B071QZ5D7L/ref=sr_1_8?crid=3DW1JWM53XAOL&dchild=1&keywords=powered+usb+3+hub&qid=1588940942&refinements=p_76%3A419158031&rnid=419157031&rps=1&sprefix=Powered%2Caps%2C149&sr=8-8&swrs=43AD7910B3A36CDE55B4A8036DE4009A At the moment I’m running my laptop, DSLR and mount from their internal batteries, and my dew straps from a power tank. However, I might look into one of those solutions a bit further down the line, thanks
  9. Thanks for tip - looks like the CPWI software is definitely compatible with my Evolution mount. I’ll probably download it and have a play Tbh, even though my mount has built in WiFi I really wouldn’t trust it to connect to anything for extended periods. It drops out regularly when I’m using SkyPortal on an iPad Pro stood right next to the mount. It’s really frustrating, and I’ve had to redo alignments over and over because it’s dropped connection. I’m assuming the cable to the mount would need to go from a USB port to the mini-USB on the handset (which is still serial I think)? Yes, I have it on a wedge. It’s definitely made a difference to how long I can expose. Not having experience of EQ mounted scope I do find it very fiddly, but the biggest downside is I can’t image some targets - the mount will point fine, but with no room for the imaging train as the base is in the way.
  10. Hi folks I’m hoping someone can offer me some clear beginner advice on PC/camera/mount connections and cables for imaging/guiding please. I realise the following will be second nature to most of you, but at the moment I keep reading and re-reading articles and all I succeed in doing is giving myself a big brain freeze... For guiding my naive assumption was that for early days simplicity I could just connect the camera to my mount via ST4 and to the PC by USB3 cable... then I discovered the Celestron Evolution mount doesn’t have an ST4 port. Doh! So, I think I need to use ASCOM and have installed it. However, apart from a vague notion that it’s the spider in the middle of a web of hardware connections, that’s all I really know about it. I need a clear path please to a) what bits I physically need to connect to what and b) what specific cables/hubs I need to link all together. Ideally I’d like to use as few cables as possible and (bonus) be able to route all to my cosy kitchen (5m from mount). Once I get everything correctly connected hopefully I might then be able to figure out the software side of things, but any pointers to speed up the process would also be very much appreciated as I feel like I’m facing a learning cliff here. Thanks in advance My hardware: Celestron 8” Edge HD with 0.7 reducer and wedge on an Evolution mount. ZWO oag and ASI 224MC as a guide camera (has USB camera cable and an ST4 cable). Celestron focuser. Canon 700D (unmodified) with USB camera cable. Dell Inspiron N5110, 8Gb RAM with Windows 7 (about 6 years old). It has 2 x USB3 ports, 1 x USB2 and a USB 2 with E-SATA and Power Share. One 5m active USB3 cable (currently used for connecting my Canon to my laptop). My installed Windows software: ASCOM platform along with general drivers for Celestron mounts and focuser. ZWO ASI 224MC Windows drivers. Canon 700D Windows drivers. PHD2. Astro Photography Tool (demo).
  11. Thanks for that, I didn’t realise the axis settings could be varied to accommodate particular corrections.
  12. Sounds complicated I’m really just starting out and although I’ve heard of drift alignment I’m not completely sure what it involves in practice. I’m just hauling my tripod in and out atm, but a pier sounds handy - I have a spot in mind, but not sure whether I could get away with building one
  13. Yes, StarSense first then ASPA, but then I repeat the StarSense alignment - a sequence I found suggested in a separate thread which also suggested rinsing and repeating until there’s no further improvement. I’m working through SkyPortal on my iPad Pro atm rather than the handset.
  14. That’s encouraging, thanks Michael. I haven’t been guiding, but I’ve just ordered an oag (something else to learn and get to grips with... ) Hopefully I’ll be able to tweak down to 5 arcmins with a bit of care.
