  1. Nit picking but the Guardian reviewer can't even get the number of episodes right. Do they not realise that maybe the audience hasn't watched all of Brains previous shows.
  2. Just watched the first episode on iPlayer and have to say I enjoyed it. Agree that there was not very much new content that hadn't already covered in his previous Wonders series, but that was 11 years ago. Have to say I did not see any reused footage. Really not sure what people want from this series. Do they want deep astrophysics discussion, is so then that's more of a one off Horizon episode. The 5 mins at the end which is a common BBC trait where they show actual scientists involved in some of the covered content is always interesting. As other people have pointed out its better than most of the garbage on TV these days.
  3. Thanks JimJam. You are right I don't think I am missing any functionality, other than software stability and maybe improved focusing algorithm's. I have a good old CCD which is still serving me well so I think you maybe right about the CMOS focused. I'll stick with version 2 for the moment. Still trying to get outside to setup my new Pegasus FocusCube, its either cloudy or too windy!
  4. Thanks. I agree there is a lot of nebulosity what with the columns of twisted knots of hydrogen gas. I will be definitely targeting OIII later this year.
  5. Having not posted an image in a while and after finding some subs from last year I thought I would have some fun with creating a starless image of the core of the Heart nebula, Merlotte 15. I have been a bit lazy with cleaning all of the stars but not too bad if you don’t zoom too much… This is heavily cropped despite being imaged from the longer focal length of the Celestron C8 OTA: Celestron C8 Mount: Skywatcher EQ6-R Pro Camera: Moravian G2-8300 – Mono Filters: Chroma Ha 3nm 5x1200s exposures of Ha (100 mins) at -25c Total: 100mins Only 5 subs so not as much data as I would have liked. I had planned to add OIII but a combination of poor weather and location put an end to that. The full image with stars is posted on my Flickr account (link in signature)
  6. Thanks. I have not tried NINA yet. I guess I am being lazy as I want to get up to speed with my new focuser rather than having to learn a new application as well. Interesting about yearly plan I did not realise you can forego the upgrades. Maybe once I have tested my focuser (weather permitting) I will have a look a NINA.
  7. Hi, I have been using SGP v2 for years and it has served me well with very few issues other than the occasional drop out or annoying window behaviour. As I am about to receive a new Pegasus auto focuser I thought I would take a look at the latest version of SGP. So v3 seems to still be the current versions although I see that a v4 is in Beta. What I found slightly disappointing is that as well as a one off payment of $149 they have the dreaded yearly subscription fee model of $59 thereafter. As my new focuser is fully supported on v2 so this is a bit of an ask. Looking through the features list I don't see much that v2 cant do, is it mainly for new users with later CMOS camera support? Is there anything fundamental in the way focusing works in SGP v3 (or the v4) that makes it an essential upgrade? Thanks
  8. Well I finally caved in and purchased the Pegasus power box Ultimate v2. It’s certainly not cheap especially when adding on the dedicated PSU and other shorter cables. To be honest I could not find a better alternative that would meet my requirements. All other options were compromises which defeated the point of the whole endeavour. Hopefully this will help my setup times and get me imaging more often. It also offers the option for other ideas. A USB compute stick could be an interesting project. Thanks for everyone’s advice.
  9. Thanks guys. Saved me some time and hassle. It did feel the further I looked into the details the more I suspected it was not going to be suitable., particularly without a compatible CCD camera.
  10. As I have to setup my kit each time I go out and image I am looking at helping speed up the tiresome process. I currently have a USB hub which helps reduce some of the cabling but I would like to consolidate the power as well. For this I have been looking at the Pegasus Powerbox 'Advanced' model. One of the issues is that all of my device are USB2 and the Pegasus only supports x3 USB2 devices with the last one only working with USB3 devices. This would mean either having to plug the forth device directly into my laptop or adding an additional USB hub which seems to contradict the reason for buying the device. The 'Ultimate' version is double the cost at an eye watering £540 which for an extra USB port is not really an option. I then noticed the ASIAIR and began looking intothis It has x4 12v power outputs and x2 USB3 and x2 USB2 ports, do anyone know if the USB3 ports allow USB2 devices to be connected? Secondly I do not own a ZWO camera and therefore I wonder if there is any point looking at this as a alternative? It would suggest because of this I would still need my laptop which is fine by me but would it actually work? As the device does not have a USB B output it seems the only outputs are Wi-fi or Ethernet. How or will this work with my Windows 10 operating system. Does the Wi-fi or ethernet send new COM ports to Windows? I am not concerned about having to use a laptop though of course controlling this from a tablet would be nice in the future. For the moment its about helping me reduce my setup times. Lastly the maximum power output of the ASIAIR is reports as 6A whereas the Pegasus is 10A (maybe 12A?). I do not know my exact draw but would imagine it maybe close to 5-6A, (Mount, CCD, Dew Heater.) Thanks.
  11. Thanks. It is odd that the first port is USB3 only when the others are both USB2/3. Historically astronomy equipment is always behind on the technical front, lets be honest we have only just seen serial ports finally being replaced with USB ports. My setup requires me to move everything each time so although not a major problem with plugging mount to my laptop it starts to lose its appeal. The Pegasus ultimate is over double the price which makes the alternative hard to swallow. I have a USB hub and all of PSU's velcro'd to the mount's legs which helps speed setup a little but cabling is a pain as much of it needs disconnecting each time. Need to give it more thought as the idea is to try and reduce setup time but not sure I am going to see much benefit from this.
  12. Thanks for the confirmation. Whilst discussing the Pegasus unit I looked at both the advanced and ultimate versions. I only have USB2 devices and I need x4 USB ports. The product specification states that only three of the USB3 ports can be used with USB2 devices, thats an issue for me. I would be connecting a pole master, skywatcher eq6r pro, Moravian CCD and a guide camera. I guess I am stuck as none of these are USB3 meaning 1 port short. The ultimate specs states x4 USB3 fully compatible with USB2 and x2 USB2 ports so no issues there. as the price difference is considerable has anyone used x4 usb devices on the advanced unit? I struggle to see why the pole master wouldn’t work but appreciate if one of the ports has no ability to use USB2 then I guess that leaves the ultimate device as the only option?..
  13. I have been watching this thread with interest as I have been considering whether to purchase a Pegasus "Ultimate Powerbox v2" unit. I am tired of wiring up power every time I set up not to mention the risk of cable snags. I am really just weighing up whether the unit will actually bring me the full benefits as I already have my USB connections managed with a separate hub. It would be nice to have on a single unit but if it still means unplugging lots of cables then no point. That aside I read from the Skywatcher EQ6R Pro Manual that the power requirements are DC11- 16V 4A? I am only power from the mains so do not have any concerns on having enough power. Presumably the mount actually draws 13.8v and not 16v?
  14. Sorry I don’t have any details in the gearing. Would interested to hear how you get on
  15. Sounds like a power issue to me. Have had an AVX for 5 years. Use to run on a battery and experienced all sorts of weirdness, including the mount diving down to look at the centre of the Earth! Try mains power, though appreciate you will need to purchase a PSU to confirm this. The Baader one from FLO is excellent but not cheap....
  16. I really like the composition. I might give it a try with my Star 71, never considered a widefield image on this area.
  17. Thanks. I have to setup and pull down my kit each time so would need it to portable. I guess the it could be adapted to allow this.
  18. Having recently upgraded my mount I am looking to try some imaging with my Celestron 8" again. Now I know this OTA is not ideally suited to imaging but with the F6.3 reducer and knowing that a certain degree of cropping the edges will be required I am willing to give it another go. I have seen some very impressive results from this OTA and the fact its Galaxy season its giving me an opportunity to continue my imaging. My question is what flat panels do you guys use on the larger OTA's? For my small refractor I use a 3" the Aurora Flat panels which whilst are not always regarded as being the most solidly built accessory it has served me very well. https://www.gerdneumann.net/english/astrofotografie-parts-astrophotography/aurora-flatfield-panels/uebersicht-aurora-flatfield-panels-overview.html However paying 155 euros which lets be honest will be £160+ with shipping etc then that feels a little more than I would like to spend. Any ideas? Please note that I have zero DIY skills so really looking for a ready made solution...? Thanks!
  19. This is my final image with my Celestron AVX mount. Due to poor imaging conditions so far this winter and the fact the nebula is rapidly disappearing behind a neighbour’s house, it as usual not a great amount of imaging time. HA: 75mins (Chroma 3nm) 3x1500 secs O3: 2.5 hours (Chroma 3nm) 6x1500 secs Total: 3.5 hours. The fact I have only been able to get 75mins of HA (3 subs?!) gives you an idea of the lack of opportunity. Still I wanted to at least get the chance to add O3 for a Bi-Colour image. (Click image for a better perspective)
  20. Be aware the handset display alignment. If it says zeros across the board then it is likely that that is not correct. Been a while but check out the AVX Mount thread. It discusses this on there in fact I recall posting threads on there about handset alignment myself. That said if you are getting good stars then looks like you have it sorted.
  21. I cable straight to my laptop. I think the mount one is ST4 guiding only. I use PHD2 with pulse guiding. Cables are my nemesis and have recently worked on taming them. Factor in cable for camera, maybe a polemaster not to mention all of the power. Tearing in all down after each session is a pain so spend time on making it easier for you if you have to setup each time. Obviously the AVX does not have a huge payload capability so try to keep weight down. My tripod is covered with Velcro so I can attach power supplies to. Check out you tube for ideas.
  22. Thanks Micky. That’s very useful information. Will arrange a session exclusively for guiding despite the draw of doing imaging instead!
  23. I have / had an AVX. I plugged a serial cable into the handset (the one that comes with the mount is fine) and then had a USB gender changer so that the serial went to USB on the laptop. Then had a USB Guide camera that connected to the laptop. Used PHD2 for guiding and SGP to control the mount and camera. Don't have any guides. Be patient with the AVX but I managed to get 25 mins exposures with pin sharp stars. Though I was using a short focal length and OAG to get this. Good luck.
