  1. ADM MDS Series Dovetail Adapter. Attach accessories directly to a MDS series dovetail bar. Incorporates a split clamp design that grips the dovetail bar along the entire surface of the saddle and will not dent or scratch the dovetail bar. The dovetail clamp has a large “T” handle locking knob for tool free operation, spring loaded jaws, anodized aluminum and stainless steel construction. Handy for attaching other items to your bar. I bought these to mount a guide scope on top of my main scope but changed scope which already had attachments. These are normally £40 each. https://www.admaccessories.com/product/mds-pa-mds-series-dovetail-adapter/ £40 the pair including postage. Paypal friends and family or you pay the fees.
  2. Just added a lot more colour for the colour addicts. Neutralised background and done a colour correction.
  3. Thanks Mark its my 5th or 6th ever image I was just messing with my back focus and decided to take a short amount of exposures
  4. First time using pixinsight. Huge learning curve.
  5. Hi yes they are. 2people were interested but did not go ahead with the sale.
  6. Let us know what your tracking RMS is like. Hoping for around 0.8 RMS with good polar alignment.
  7. SOLD Used twice then upgraded mount. This is the better cable that does not change com ports each time you plug it in. So you don't have to keep reconfiguring and finding the com port. Works with Windows 10 drivers automatically for me. Paid £38 including postage. Yours for £25 including recorded delivery. Can post tomorrow morning.
  8. Just arrived 5 minutes ago and I looked at the forecast and got this
  9. Hi David good questions 55m scope fits so 60mm guide scope or above would be preferable.
  10. The Enhanced Moonfish® 30mm 80° ULTRAWIDE is a very serious wide-angle 2" eyepiece. The eyepiece has five elements of fully multi-coated (FMC), high-index glass, with a high light transmission, allowing your telescope to be pushed to its magnitude limits.at a very affordable price. Contrast and correction is good for very low powered wide-angled viewing of those larger deep sky objects. Concealed beneath the new rubber eyecup, great for those cold winter nights, you'll find a thread to accept M49 camera adaptors. Perfect for afocal camera imaging with a wide variety of film and digital cameras. Main features Focal length: 30 mm Apparent Field of View: 80° Fully multi-coated Barrel: 2" / 50.75 mm Rubber eyecup M49 camera thread Elements: 5 elements in 3 groups Eye relief: 22 mm Field stop: 40.8 mm Weight: 570g (1.2lb) Length: 114 mm (4.5") Boxed unused £85 including 2nd class recorded delivery
  11. HI they were bought from new, they have not been modified they are just over 1.5 inches long if that helps. It's probably because mine arent screwed right in like there's. Heres another picture of them screwed in. Hope that helps.
  12. I never got round to using these. Complete with nylon tipped screws to protect your hardware. Quality metal rings from ADM. They are £80 plus postage new. https://www.rothervalleyoptics.co.uk/adm-guide-scope-ring-set.html I can get them in the post tomorrow morning. £48 inc Postage 2nd class recorded delivery.
  13. SOLD I have been extremely happy with this mount but it's time to upgrade to something more substantial. It was Hypertuned by Dark Frame Optics a few years ago including belt drive and ceramic bearings. Cost £508 I sent back the mount late last year for a checkup and service and is warrantied for another 18 months. I am asking £895 £795 (for quick sale) on this mount which I think is a fair price. Collection only because of the weight and size. Regards David
  14. I will take a look right now many thanks.
  15. Just had another play maybe too much but I think I have more colour
  16. Thanks for the info. I will try longer exposure again. Having huge problems with all these Elon Musk satellites wizzing across my frames so thats why I shortened them. I am wondering how to get more colour in photshop do I increase the saturation?
  17. Unforunately I don't have the expertise to post process. It a little dull. I think the data is ok though.
  18. Just a quick 20 minute post process in photshop. 50 x 45 second Lum 30 x 60 second Red 30 x 60 second Green 30 x 60 second Blue Gain 75 Offset 15
  19. Thanks for the reply. That makes sense. I shortened it by 0.5mm and it made it worse. I need to put that spacer back on and add another Thanks for the help.
  20. Hi here is an example of where my elongated stars are from the direction they are going can you tell if I need to shorten or lengthen the back space? Cheers David
  21. Yes I am hoping so. As soon as I get a few hours of clear skies I will restest with a short 20 second exposure to eliminate star trailing. Hopefully it will be better.
  22. Hi I have uploaded my highest scoring Lum file from a couple of nights ago. There is some funny star shaped in it especially around the edges. I am using A TS 107 Triplet with a 2 inch TS optics 0.79 focal reducer. EFW filterwheel and a Zwo asi1600mm pro Cmos camera. By using the the adapters and adding them all up I get 56mm backfocus. According to this chart from TS Optics I need an extra 1mm. Information from them here.... Back Focus - distances from the T2-thread to the camera sensor depends on the focal length of the telescope: ♦ Focal Length to 350 mm .... 70 mm ♦ Focal Length to 420 mm .... 65 mm ♦ Focal Length 450-500 mm ... 61 mm ♦ Focal Length 510-600 mm ... 58 mm ♦ Focal Length 610-700 mm ... 57 mm ♦ Focal Length 710-790 mm ... 56 mm ♦ Focal Length from 800 mm .. 55 mm My scope is 700mm So I am rigth on the end of one of those calculations. Today I stripped everything down and checked everythintg. I was using a 1.2mm washer to get the extra 1mm distance but the washer was a hard plastic type and when I measured the gap it was more than 2mm. I managed to find some soft type washers in my old ZWO box remove the old one and put a thinner one in which is giving me around 0.9mm gap. Giving me a total of 56.9mm. Instead of 58.1mm Do you think that should fix the problem? Can 1.2mm out make my stars look like this or have I got another problem. Not had chance to take the scope out to test the new configuration due to the usual clouds. Any help would be great. Single frame is of M3. Thank you for any help in advance. 2020-05-20_00-25-06_Lum_-20.00_60.00s_0018.fits
