  1. There are just so many moving parts on this thing that the launch isn't the most nerve-wracking part. Part of me hopes that there can be many, more simple, large telescopes launched on board SpaceX Starships instead of these hugely expensive flag ship telescopes. The NSA gave NASA two extra Hubble telescopes (obviously need significant modification) that were made to point at the earth rather than away from it. Send those up! In my opinion more is better rather than best-that-can-be all eggs in one basket launches.
  2. This looks great! How do you go about framing a Dark Neb so well? Not tried on yet
  3. I had all sorts of problems with the StarXterminator. It'd remove the stars but leave large areas of background and fill it with a base colour - no noise, just smooth - stands out like a sore thumb. I think the issue is halos around the stars are sometimes detected as stars. On the other hand, your image looks bloody amazing and it's done a fab job for you! Thanks for sharing.
  4. It's worth pointing out that some ZWO CMOS cameras actually have a dew heater built in - my 2600 does. Not sure how many models have it.
  5. Cheers dude. I ran out as soon as the kids were in bed and set up as quick as I could (no pier) - by the time I was focused I had time for 30 seconds of sub only, with no polar alignment. I aimed the mount at a tree that's roughly north
  6. I've got no idea, it actually fell out sideways, as in rolled out, not up or down sliding. Very odd. I'm thinking it looks "ok" too, as in, the stars are equally crap everywhere.
  7. No idea what happened, I swear I had it securly in the mount by the dovetail. It landed dew-shied first and chipped a bit of paint off the corner. My 3D printed top-rail then took the rest of the impact. From what I can see the glass looks fine. To check it last night I managed to get set up under clouds and got one 30 second sub before overcast. I couldn't polar align. Can anything be said of this sub that scope is ok/not ok, or do I need more data? Cheers Preview_000_30.0s_Bin1_gain100.fit Preview_000_30.0s_Bin1_gain100.tif
  8. Makes my problems feel small man. Love it.
  9. It's more of a moral decision to not use Facebook products. As I say, I'm the outlier and it does screw me over!
  10. I'm looking to develop some rules of thumb which I can stick to. I am pretty much exclusively an imager. I have an ASIAIR Pro which can control the dew heater straps % power through the app. I don't think it's in any way automated though, so unless I'm up I need to set and forget. Obvs if I'm awake I can adjust. Because I image on battery a lot, the dew straps work out as one of the biggest drainers, so I'd like to make this as efficient as possible. So on my 115mm refractor, how high in % terms should I be running the Lynx Astro dew strap? The colder it is, the more power I run through it? The more degrees below dew point, the more power I run through it? Just whack it on 75% and go to the pub? I've seen plenty of arguements on various forums about where to position the strap, but not a lot on how much power to give it. Cheers
  11. Thanks Stuart. Unfortunately I don't use Facebook (which seems to screw me over a lot) so I guess I'll just have to import what I want from Germany!
  12. I've tried to email a couple of times in the last 2 weeks, tried to call a few times - no response to email and no one to answer the phone. I have a stock enquiry (website says to email to check stock). I don't want to pay them if they're out of stock and won't be possible to get a refund! Supplier reviews threads are all locked, so posted in the only place I could think would accomodate a thread such as this. Cheers
  13. That is a ton of detail from the city with no filter, Lee. It's definitely not over processed like lots of M31s I see. Nice job mate
  14. This is going to be so rad when you get the mosaic done. Nice work man!
  15. Cheers mate! I only have access to Northern skies from my garden so I'm on the hunt for good ones that 500 to 800mm focal lengths will excel at if you have any tips - my horizon in Stellarium attached.
  16. This is my 2nd attempt at photography, and this was way harder to process than the last. Starting to feel I understand what over-processing is! This is only one hour of data so I need to start actually getting some reasonable time on targets and hopefully that will help with the noise. The 2600MC is quite something. Still trying to shoot things with the light-polliution busing L-Extreme filter. I need to work out what's going on with tracking or field flatness or something. Cheers!
  17. Yeah it should apply. I think you'll end up making HA = Red and OII = Green and then sythesise a blue channel from 60% red and 40% green after some curves and level adjustments
  18. Take a look at this video from Luke who explains a lovely way to process HOO. This is for OSC data.
  19. Some fool,- definitely not me - was trying to drink a glass of Sainbury's Cava whilst adjusting the scope on the mount. The mount was pointed at the NCP, and the dovetail slipped through the mount grips and to the floor. 'Definitely not me' managed to 'save' it from concrete with the interjection of a well placed foot and not a small amount of Cava was lost. After I got it back on I noticed that the 3" Crayford Focuser was slipping out and the EAF could move it out, but not back in/up. I Googled it and properly tighted a hex screw and that issue appears to be fixed. However, when I took the flats from last time I was out vs this time - I get something different - which worries me. The scope seems to be totally shifted over on the flats. I've uploaded a single light frame from last night also. Any ideas? EDIT So I have found this morning that loosening the hex bolt under the focuser moves the flat circle back to centre. However, this also means the focus moves loosely and falls back. I can find no way to loosen the hex screw and keep it tight - there appears to be no opposing tension screw on the top. Light_NGC7822_120.0s_Bin1_gain100_0026_1.fit
  20. Awesome thank you for those they are going to be helpful. My son has decided that we should try for the Bubble Nebula tonight so we'll give it a go
  21. Hey mate I'm hoping to use the ASIAIR I have so I can monitor it from the house. If I can't get it all to work then I can fall back to the laptop for sure. I need to work out a method of getting things framed. Is it possible to plate solve an existing image off of the internet and get the scope to plate solve to that to help with framing? So you kind of get the scope to where it needs to be and then manually slew to the exact place? I'll dig around, I know I saw somthing on Telescopius.
  22. Ah right ok, thanks for this. Lee said below he photoshops them out. Hey Lee - I found your website the other day. You've clearly put a lot of work in to it and it is becoming a great resource. Cheers for doing what you do. Helpin' us nubs. You capture here tells me that 90mins of data aint gonna cut it and I need to get more blue nebulosity data. Dude that Samyang is just nuts. Nice one.
  23. Wow thanks mate, honestly it's all don to that PI tutorial I linked. And the fact the Optolong L-Extreme / 2600MC are just so outrageously good. Lots to learn but I'm excited to get more data. That was only 98 mins
  24. Hi This is my first image of anything so I'm sure there's a million errors which I couldn't even begin to appreciate. I couldn't get my guidescope to focus at all so this is unguided. Good polar alignment thanks to NINA's Three Point Alignment might have saved the session somewhat. This is 49 x 120s subs through the Optolong L-Extreme Filter taken last night after I lobbed the guide scope in a bush. 11 rejected frames from me poking said guidescope while imaging (lesson learned). Bortle 8, Dartford, UK Altair Astro 115mm APO from 2013 0.79 TS reducer 2600MC Pixinsight to put it together and stuff. Followed Lukomatico's noob guide and he's the man (https://www.youtube.com/watch?v=QV6ObLVRvNk) Some weird halos on the stars, no idea what that's about. Framing - no idea - just told the scope to aim at it and go. Probably need to work on that strat. Cheers
