  1. here’s a picture of the setup after putting all together - albeit inside - update - after I got all equipment put away, sky cleared up so quickly set up again, and after a rough polar alignment (and then walking into my mount by accident) I was able to get a few, really short shots of M51, which I’ve just touched in Lightroom. Bear in mind this is only a 30 second exposure with a full moon. Pretty happy

  3. Ffs I’ve looked it up and this wasn’t needed at all. The lack of information on Baader’s behalf is appalling. Really confused on what I need now… just want to get out with this new tube
  4. So the spacer I bought was the baader one the recommended… I’m worried it requires this stupid Canon EOS protector T Ring thing. https://www.firstlightoptics.com/adapters/baader-protective-t-ring-for-canon-eos.html
  5. I feel so silly here… can’t seem to figure out where to screw the extension into
  6. Got it. No worries. Thanks for the help
  7. Hi again everyone, so managed to get home from university to get a look to my gear. How do I unscrew this T2 thread for the coma corrector and add my extension?
  8. Hey everyone!! Just bought my SW 130pds, a Baader MPCC III coma corrector and an M48 adapter for my Nikon D5600 Already have a belt-modded HEQ5 with the EQMod cable. Seriously excited... all I need now are clear skies and some time off from my Astro-Physics course at uni 😅 Clear skies all!!!
  9. Just thought I'd let you guys know that I just bought all the gear... Skywatcher 130pds Baader MPCC III Nikon M48 Adapter The SW coma corrector was out of stock so went with the Baader one instead, hopefully all should be fine. Thanks for all your help and clear skies!!
  10. Just meant there were 44 of the T2 adapters left... wasn't really necessary looking back at it. Astro-Essentials supply M48 adapters so I'm assuming they're just as good as the one you've linked from Ali-Express. I'm more inclined to buy everything from the same company in the UK so that delivery times aren't all over the place. Thanks for your help
  11. hey guys... So they've just delivered 5 new 130pds, 1 new SW 0.9x coma corrector and there's a load of 44x Nikon T2 Adapters. At this point I'm thinking of getting those, what do you guys think?
  12. I think so... which would you recommend between getting the M48 or the T2? I'm going to assume the T2 as it will require less spacers to reach the additional 8.5mm required?
  13. Okay, so after doing a bit of reading I'm beginning to realise its not so much about "reaching" that 55mm, its more a case of not exceeding that 55mm mark because then you'd end up not being able to rack the focuser in enough to be able to reach focus! Where you mention "flange", I'm getting that its the distance from the sensor of the camera to the "lens", or in this case I'm guessing the scope? So does this 55mm of back focus in the coma corrector include the 46.5mm of the flange for the Nikon F mount and then also however long the M48/M42 adapter is?
  14. Hi, Thanks for the reply! When I said "I get it" it was more so in the terms of what's actually happening for focus to be reached i.e., how the light focuses and such, I just recently finished my module in my astrophysics degree on Light & Optics so I appreciate that, I was more so confused as to whether the coma corrector will help me reach - or in this case, remove, as you've said, - the required back focus - per say. What I'm grasping from Barbulo is that I don't need to worry too much as the coma corrector he's mentioned is the one I was looking to get, so if his works fine and he uses a camera with an APS-C sensor, then they should act fairly similarly.
  15. Hi everyone, So I've been looking to buy a Skywatcher 130PDS to go along with my Rowan Modded HEQ5 and Nikon D5600, but I'm struggling to grasp what sort of back focus I need. I appreciate the concept behind back focus, but I don't know what equipment to buy. I know I need a coma-corrector at the least and an M48/T2 adapter for the camera, but how much back focus that provides, and whether or not that's enough I don't get. If anyone has any advice they could give me it'd be greatly appreciated. Thanks, Oisin
  16. Thanks for the reply, is there any way I can account for the coma, and I assume that the stars being elongated is due to a too long exposure time.
  17. Hi all, Would anyone be able to explain why dss is only counting 4 stars in this image when there's clearly more. Could be because I forgot to take the files as RAW rather than as JPEG. Thanks, Oisin
