  1. Past hour
  2. Hi Steve, I have the exactly the same issue only difference being the mount a Mesu, no idea how to fix it! I've downloaded cartes du ciel for now but I would also be glade for information on how to get Thesky6 working with Ascom/Windows10? Peter
  3. LOL. yes agreed - stuff never looks quite the same as textbook examples in any field. TBH I was trying to avoid naming names. Only because I've raised the issue with the supplier and Id rather post the whole story rather than cloud folks judgement about a scope/supplier that's probably perfectly good. Hope that makes sense!
  4. That’s a bummer, Robert. So my ‘offline’ suggestion regarding the BVs is redundant. Above advice all sound: SGL first, ABS second ... and beware the rest!
  5. This is absolutely beautiful mate. I could only wish to come anywhere close to this processing skills. I'm like most am learning.
  6. Maybe i need to ditch the BPP script and see if the image gets any better to begin with. Would appreciate if you could PM me the process icons and i'll save them and work through them. Cheers mate
  7. Gosh that is a bad run of luck. Are these from the bay of fleas by any chance? Touch wood I've only every had one problem which was a pair of binos from eBay described as in excellent optical condition but which had fungus on the prisms. That ended up with a PayPal dispute and my money refunded so all ok in the end. I tend to buy astro kit from here or AstroBuySell and don't think I've ever had a problem in large number of transactions even overseas.
  8. Hi All, Here's my latest image. I'm not entirely happy with the results but then again here i am posting this image for comments and criticism and looking for ways to improve. Ha: 80 x 300s SII: 80 x 300s OII: 80 x 300s Processed in Pixinsight so kindly let me know what i can do in PI to improve this image because that's all i know Thanks in advance. Regards,
  9. Hopefully your run of bad luck is over. I have never had a problem buying used items. Come to think of it, I have bought them all from members of this site. That’s probably why.
  10. I did get a used star atlas in as new condition for the princely sum of £3! I'm hooked on bargains, but sometimes buying new is ultimately less hassle of course.
  11. I'm not an optical expert and the only thing I can say regarding Airy discs and collimating as they never seem to look quite like the textbook examples Dave BTW. which scope is it ?
  12. Hi Vlaiv. Give it a go my processing skills aren't great. Whenever someone posts their data i struggle with it. I rely on good data which needs very little processing.
  13. So.... Although I don't own either of those two telescopes you mentioned and neither the AVX mount, but I do have the Celestron Advanced GT mount with an Evostar 80 ED refactor and find it more than adequate for AP, just make sure the mount is polar aligned or you will run into guiding issues. I think the mount you have will be more than capable with a 80mm scope. One the subject of refractors, have you considered 2nd hand? There is a Explore Scientific ED 80mm on ebay at the moment (Mint Condition is says) and although you haven't mentioned about camera's for imaging & guiding but maybe the pennies saved can assist with the additional kit for AP as auto guiding is a must.
  14. Hi Dave. Funny you say that, somewhere I read about tube current causing probs so I also wondered about temp - both ambient and sensor temp. I recently changed my default cooler to -15, previously -10, and wondered if this could affect it. But the latest test was done with and without cooler, and no difference I could see. Possibly to do with ambient I guess, but nothing extreme there, and not much change over Test period. anyhow, wouldn't any optical issue like pinching or current also affect Airy disc shapes?
  15. Moonshane my friend, just wondering, IF, as you state, you will use the top of your tripod head re the mount proper, how will you cope with the screw that goes through the centre of said mount head that fixes the HEQ mount in place?, won't there be a need for some form of space so as to be able to screw the mount up firmly? or am i missing some thing, cheers mate; i just might do the same as you propose as, i won,t be going out and about with my set up but just in the OBS. Best regards, Tom.
  16. I honestly don't believe I would be able to come even close to your processing.
  17. I don't often post here but wanted to give a shout-out to CFF. I took delivery of the new scope in early March and this is the first light. Not the most challenging of DSO but its great for picking up any collimation issues. I haven't actually touched collimation yet, still trying to find a window of opportunity with decent seeing and its a little off but straight out of the box the scope is performing well. Kudos to Catalin and the people at CFF. Great people to deal with, great customer service, loving the scope. CFF RC250 F7 First Light - NGC5139 Details NGC5139 RGB 30:30:30 in 5 minute subs from Sydney CFF F7 RC250 with custom field flattener. The focal length is 1790. STL6303e AP900 Processed in PI, really basic stuff, calibration, some light touch NR, photometric colour calibration followed by HST. Clear skies
  18. A brief rant and a 'buyer-beware' for other novice astronomers such as myself, or those that generally find a good bargain irresistible. Other than my telescope (thank the gods!), my last three used purchases online lately seem to be total duds or poorly looked-after. The first was barlow that appeared to be stored next to the kitchen hob of a busy chip shop. I did manage to disassemble and clean the grease to an acceptable level of use! Next was the binoviewer. Below is a photo of the internals described as used but 'optically fine'. Maybe the mirror breakage happened in transit (though it was very well wrapped in a protective case) but that doesn't explain the greasy black fingerprints on internal glass...?? Last was a used O-III filter that apparently de-laminated sometime in the Thatcher era, leaving an artistically-attractive off-centre crazed pattern, though probably not very effective as an O-III filter on a scope any longer. Fortunately the binoviewer and filter sellers have instantly accepted a refund, so it's hardly the end of the world, but I seem to spend half my time hanging around the post office queue lately sending stuff back. I think I will be slowly saving up for new items instead, as time is in short supply these days... Mini-rant over and buyer-beware - at least sometimes. Good luck all!
  19. Does it alter with temperature change ? it may have been colder for the first picture. Dave
  20. Hello,im having trouble trying to screw this type of polarscope to my eq5 mount. As you all can see in the added pictures,i try to screw it but it doesnt fit in the mount and doesnt have a Threaded ring of its own. I don't know if i'm doing something wrong. Would appreciate your help in this problem. *Iv'e added another photo of polar scope with threaded ring for comparison.
  21. Today
  22. Thanks Charl, you're not missing much just a couple of average proms ATM, I've got to get on with my list of chores today as I did nothing yesterday but keep an eye on AR 2378 Hope you feel a bit better soon. Dave
  23. Yes, the focuser on the new ED80 should fit on the tube of an older SW ED80. I fitted a two speed focuser from a 2 yr old SW ED80 on my Orion ED80 (the predecessor of the SW ED80). Just three screws.
  24. great shot Dave, day off for me today, not feeling too good. clear skys. charl.
  25. great shots David, day off form me today mate, i think ive come down with something "prob fish flu " clear skys. charl.
