  1. Past hour
  2. That's pretty good for the short integration time and sky quality. There is a fair amount of detail shown in the spiral arms. Alan
  3. Great image Peter. I got all excited then thinking you had done it from the UK until I saw you did it in Spain. Going to Spain on Friday, but will only have a skytracker and camera lens available. Carole
  4. Use your lowest power eyepiece to help with the finding process. Try and get the Rigel finder as closely aligned with the view through the main scope as possible. You can do this in daylight using a target that is a mile or so away such as a tree top, church spire etc, etc. Thje Rigel view won't show M13 but if you can put the "bulls eye" where shown on the star chart below, M13 should be in or near the field of view with a low power eyepiece in the scope:
  5. Here ypu go. https://www.amazon.co.uk/gp/product/B07KM9XF19/ref=ppx_yo_dt_b_asin_title_o02_s00?ie=UTF8&psc=1 Measurements are 10cm wide by 16cm high by 3cm thick. Seems quite well made.
  6. At least the box won’t be wasted. Will come in handy one day for shipping something.
  7. My primary reference to pixel size was in terms of Ha solar and Lunt 50 - very small focal length scope, but yes, 127mm one could well use 174 chip with suitable barlow for planets.
  8. Ridiculous! The sooner packagers have to pay the full environmental cost of packaging and its disposal, the better!
  9. Clock mechanism in case. The pendulum rod is a steel rod from an ancient wall clock but seems to be too flexible. I may try a dowel rod instead though the air friction will be much higher.
  10. Could you put up a link for the pouch please? Also what dimensions is it? Ta.
  11. NGC 4038 and NGC 4039 - known as the antennae galaxies in Corvus. Two interacting galaxies causing giant tidal streams and starburst star creation as they interact. 21h20m total integration (48x600s and 56x300s L, 37x300s R, 32x300s G, 34x300s B). Image capture on my dual rig in Spain (APM TMB 152 LZOS refractors, 10Micron GM2000 mount, QSI6120wsg8 cameras).
  12. For the data connections (all the wiring to the VM110 board) you can use thinner wire like 22 awg as none of it is high current. Only wiring going to the relay board COM, NO and NC contacts, motor, 12V battery, fuse, rigel system, and associated switches needs to be of 16 awg or similar (ie. any wire that can be carrying current going to the motor.) Using multi-strand wire of a similar overall thickness to single core is fine. It's current rating is only slightly less that the single core and won't be a problem in your case. Alan
  13. I have no idea where im going wrong then my telecope is cooled, colimated and is under very hard skys with no light polution. Im using a starguider ed 8mm which is roughly 93 mag so maybe i need more magnification maybe im slightly off the target.. whos knows My finder scope is a riger Quickfinder and im strugglong to align it.. im sure thst doesn't help. Atleast i know what im looking for now
  14. Yes that's true as I had that issue with my 80edt and is much better on a 120 and above frac. the op has a 127 edf so he has a wider choice maybe? ton
  15. And here's a good pdf on how to analyse your guiding: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=2&ved=2ahUKEwjiqvny3rviAhUwVRUIHXCbDFkQFjABegQIAxAC&url=https%3A%2F%2Fopenphdguiding.org%2FAnalyzing_PHD2_Guide_Logs.pdf&usg=AOvVaw208LGfOpq-qd2bYGZi_iQL
  16. Here's what a PHD2 Help File says about Differential Flex: "Many imagers go into denial about this and say “I’ve got everything clamped down really tight, nothing is moving, it can’t be differential flexure.” Yes, it can be. Every single mechanical interface on the system - clamped, threaded, geared, set-screwed, whatever - has some possibility for movement. And all you need is a movement of a few microns to create a problem." A few microns is a fraction of the thickness of a hair. Your guiding may look perfect, because PHD2 is failhfully following every move of the guidescope. Unfortunately the Diff Flex means the perfect guiding is in fact wobbling the imaging scope ! So the flex of adjustable rings is a problem that will not be apparent in your guide graphs. Michael
  17. To be honest I am not exactly sure what the best reducer for a Esprit 120 is. I suspect that one of the adjustable ZWO reducers would work fine. I would always go with a mono sensor and good quality filters.
  18. That is an option, but 174 chip has quite a large pixels, and that is going to limit resolution on small scopes. It's got 5.86um pixels, and compare that with 178 for example and 2.4um pixels - that is almost x2.5 times smaller pixels, so you would need x2.5 barlow to match sampling rates between two cameras and FOV would suffer.
  19. Hi, I have a 174M hypercam and although I have yet to use it on planets, the sun comes out well as does the moon, but new are £600 and not many are 2nd hand yet. yes it's a mono but it does have a good rep. sun shot last week using 174m with wedge and 120 st. ton
  20. Hi guys, Has anyone used an mpu-9150 or mpu-6050 to support tracking or goto? https://www.google.com/search?q=mpu-9150+astronomy&client=firefox-b-m&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjNjNv23rviAhVqTxUIHSNMCNkQ_AUIBygC&biw=360&bih=412#mhpiv=9&spf=1558961188046 I'm thinking about it, but I think it maybe a lot of effort to do what plate-solving does better. Regards Steve
  21. Rigel Quikfinder to include two bases, original packaging, instructions. This will require new double sided fixing tape. In excellent condition £23 to include first class post
  22. Quick release bracket to fit Tele Vue Ring Mounts, accepts Vixen, Orion, Skywatcher type finders. Two lock screws In excellent, as new condition £22 to include first class post.
  23. Hugh Thanks for that - I'll go for the 16 awg. Peter
  24. Thanks for the replies Fella's. I was VERY close to buying the Skywatcher 200 Dob, again, just the shear bulk size put me off...And when I showed the Home Secretary she said..'Where are you gonna put that'!!!...I had Two answers for her in mind put keep my lips sealed! She hasn't actually looked through my Heritage yet, so im hoping once she does, size wont matter! and she too will be hooked, that's when I bag the 200...Up here for thinking...Down here for dancing!
