  1. Past hour
  2. I think they do. It seems to be enjoying it Regards
  3. Thanks for this, especially the way you've presented zoomed crops of the various regions of the image. I do have a copy of CCDI, which was a shared purchase a couple of years with another imager who actually purchased it (so maybe semi pirate ), but I don't understand what I'm looking at when I run the files through it, just lots of weird patterns and no instruction manual to explain them - I don't even know if one exists. Guiding was pretty good, not the best, averaging at 0.74" total RMS (RA=0.54",Dec= 0.50") whilst imaging at 1.92"/px, so should be good enough, but PHD Log Viewer reported that my PA was poor at 10', so I need to look at that. I didn't run any deconvolution, so I could try that, but that won't fix the elongation, or will it?
  4. Now I'm really depressed! So much for my dreams!
  5. Ok so a bit older and shaving? Regards Andrew PS how did you know his name was Occam?
  6. I never thought of it that way, but you are right. We do live on a cool world! Sometimes I have doubts about about some of the people we share it with!
  7. C925 and 294mc pro with Baader neodynium filter. Best 20% of 2k.
  8. The Meade 4000 plossls are the best for those adapters - they are slimmer than most plossl eyepieces.
  9. Hi All. Is there are apps/websites that will give a daily list of things worth looking for each night. Stellarium ect are fantastic, but more helpful when you actually know the skies and are hunting down specific things, or perhaps I havent found what im looking for on stellarium? . Thank you
  10. Just determined the COG. All components needed to be attached. Even a few astronauts were dumped in HST to find the correct spot.
  11. Really nice image Carole. Starnet does seem to produce really good results for me, but it doesnt run like a conventional program. Having said that it's very simple to use once you know how to run it. I hope you dont mind, I took the liberty of trying it on your jpeg. It didnt work well on the colour RGB image directly, so I converted it to a mono image, then used Starnet. I then used that as a lum layer and added it onto the original RGB posted above. It would probably work better if I wasnt using a jpeg > TIFF. Just food for thought for you.
  12. Hi, I think I’ve had too much time on my hands recently, keep reading reviews and now my head is spinning. I only recently bought my first telescope, a Heritage 130 but due to recent weather I’ve managed to have quite a few sessions and spent some time reading up on various aspects of astronomy. Have to say I am really enjoying the learning curve, happily realising I have a long way to go. I have upgraded eyepieces to BST starguiders and even though I found the dobsonian base very user friendly I saw a good deal on a used explore scientific twilight 1 mount/ tripod. That has made things much more comfortable to use and stable,standing up. I love being able to use the slow motion controls. Anyway enough waffling on, While I want to keep learning my way round the skies I do fancy a goto system to compliment it and use for quick sessions and tours of the sky with family. At this time I’m only thinking of visual so photography/ tracking isn’t the top priority. I have been looking at Skywatcher AzGti and star discovery WiFi systems. They tick the boxes in terms of price etc and FLO have told me they are very similar, the GTi being more compact. Could anybody with either give me their thoughts or has anyone tried both. They are same price but the discovery comes with steel tripod v GTI aluminium. Unfortunately the mounts aren’t compatible with my tripod. Thanks in advance for any comments.
  13. Thanks JOC..! This HST is to be hung in our local observatory. Transport will be done in my van. The device I use to work on HST, I will screw it in the bottom of my van. A friend will sit beside it during the ride. It's only 3 (long) streets away from my home and workshop. Next Sunday D-day as a matter of fact. Total weight is about 30/35gkg. Parts sticking out of the hull will be removed before transport of course. Now busy making/printing the very last smaller things, front-cover, astronauts brackets, Maybe we will put some tools in the astronauts hands. Hammer, nails, saw... Need to make a bracket to attach the WideFieldCamera3. That camera is floating outside HST while astronauts are working/installing it. We also have to find proper names to put on each of the astronauts arm patch. We also have to think WideFieldCamera3
  14. You will have to excuse the non-scientists here for not knowing what the term doping means in this respect then All the definitions that I can find for the term refer to something quite different.
  15. Occam's razor tells us it was unlikely to be a six-year old's terrarium.
  16. The ST 150 is a bit of a bargain. There is also a 150 SW at 10x the price. For the latter, FLO have an offer to save £50 if you buy the reducer at the same time. For that price you might expect them to include it! You are trading different things. The Newtonian has no glass, so avoids any chromatic aberration, that the more expensive refractor seeks to avoid. The ST 150 avoids collimating issues that Newtonian are known for. All Newtonian scopes (which includes the ones with a parabolic mirror) suffer from coma, so crow’s feet at the outer edges, which can be corrected. A Newtonian can have spiral canes which introduces four points around bright stars, which can be eliminated with curved vanes. There are practical issues with the Newtonian e.g. have to rotate the scope in the cradles to get a good viewing angle and you may want a short mount or a “booster” seat to be comfortable. Some Newtonian are big for their size e.g. some bigger ones are in smaller or shorter tubes and be less susceptible to wind etc. A camera may not reach focus on a Newtonian, otherwise the EP would be too far out for normal use. A refractor may require a pier to get sufficient clearance on a Eq. mount. Overall the best image is the one you prefer, with lots of other things to take into account. Simon
  17. 11x70 Opticron Oregon binoculars. used once on holiday last year. Includes manfrotto 222 trigger/ ball grip with monopod attachment. Also includes soft carry case. The trigger grip allows for easier and more comfortable use and gives very good stability. I now have an 80 mm refractor so these are redundant. Asking £100 posted in the UK. Cheers Steve
  18. Nice subtle detail there Geof, especially in the dark regions; the transition is very smooth. I created a panelled image of the corners and centre in order to visualise things a bit better. I agree that elongation does seem variable. More a radial pattern on the right side, and more an outward elongation on the left, but then there's some outward elongation in the central panels too. Could be a combination of focuser sag/CCD tilt/guiding; how was your guiding for these sessions? I'm having some variable tilt with my setup as well, and I suspect its focuser sag, but the images are acceptable so I'm leaving things alone! I wonder if you rotate the camera by 90 degrees and the image remains the same then you could say that its to do with the focuser and not the sensor? You could run your raw FITS images through MaxSelector (free version of CCDInspector, unless you happen to own CCDI) which can give you an indication of what the issue could be (although I find the results are a bit variable!). In order to help with the stars, could try some deconvolution to tighten them up?
  19. It unknowable if it's true or not. Regards Andrew
  20. I would check what the latest Ascom can do with the asi as it may well have changed. Regards Andrew
  21. Bet your happy with them, some great detail
  22. I dont think i'll see clear skies for days. We have something developing in the Gulf of Mexico.
  23. Thanks @andrew s for that prompt to Christian Buil's site. Cameras are almost identical, just little things ZWO and Atik have tailored to their markets. One thing I hadn't realised is that the Atik Horizon has to be powered to be used unlike the ASI1600MM Pro which (like the ASI294MC Pro) can be used via USB cable only although there's no cooler operation. I've certainly used that feature with the 294. Some features of the 1600MM Pro can't be accessed via Ascom whereas the Horizon can. All a bit swings-n-roundabouts...
