  1. It couldn't be, since yesterday was 20th.
  2. Yeah, it's all pretty well setup and like I said, after the first alignment, it puts the goto star right smack in the center of the eyepiece. I just can't comprehend this kind of error, so frustrating.
  3. Ok, I'm close to disassembling the thing, wielding the legs of the mount as weapons and going on a rampage in the Celestron headquarters to hunt down the developers of this software. Finally, I have a starry night after a month of clouds. Out I go and try to set it up and polar align the beast. What I did: 1. got the mount roughly on south. 2. placed the tube in direct parallel with the arm, pointing to polaris. 3. centered polaris physically. 4. Did the starsense 3 point dance. 5. Centered perfectly(!) on Regulus. 6. checked the polar align error. about 1" on both axes. 7. pressed a polar align. Used Regulus again. 8. it slewed away and then back perfectly on Regulus. Then it took the picture. 9. Then it slewed away and asked me to polar align with the knobs. This is what it did: That arrow is roughly Regulus. I'm not kidding. That is not a 1" error. It's not even in the remote bloody ballpark of an error. Any suggestions?
  4. Funny, I had the same thought when I had a moment to think it through. Good stuff! Thank you!
  5. Interesting. So in other words, I messed up the initial position of the tripod. Alright, I'll hope for clear skies soon (one damn night in over a month) and try all this out. Thanks again!
  6. The one I uploaded is a crop. The full stacked is the one I linked, which has some stacking effects on the edges.
  7. Thanks for the advice. I'm near the south coast of UK, but across the fence is a home for elders and apparently it is vital that they keep their yard lit with supernovae in the night. Focus is correct. I will use software next time to focus. The camera is a 6D unmodded, celestron evo mount and WO 71 lens. No tracking.
  8. Wow, nice Noah. Only saw this now. So, I tried this. My problem is that on step 9 the mount goes FAR away from the goto star. Like, I think I would be adjusting it to latitude 55 or something ridiculous. This is where I gave up on it. And yes, considering the gem now... :-(
  9. Last week I finally got a chance to use my new scope (William Optics 71) after a month of clouds and travel. While it is so easy to use and seemingly gives very good shots, the final result is underwhelming. Most likely my rookie mistakes to blame. I attached the shot as I did what I could in StarTools. It's 20 darks, 20 flats, 40 bias, and 81 30s lights stacked in DSS. DSS output is here: https://www.dropbox.com/s/10baovii9674jd0/Orion WO71 first.TIF?dl=0 What I'm thinking is that the light pollution is simply too much for any postprocessing to remove. I'd like advice from more experienced AP'ers out there.
  10. Yeah, that one does sound pretty cool. How are the results?
  11. I have a wedge and can comfortably take 60s exposures even with my failing PA skills. So, the Samyang is another camera lens suggestion. Anyone with experience with one of the refractors I posted?
  12. While Danny gave good advice, does anyone have comments on the list of refractors?
  13. I have the 24-105 f4 L for the daytime and can't see myself using a 200mm. Besides, that 70-200f2.8 is £1700 and will still only give me 200mm FL. I do appreciate the 1500mm of the SCT, so I'm very apprehensive of going down below 600mm. I'd like to do DSO of most of the Messier catalog, which includes some quite small ones as well.
  14. Ok, so that escalated quickly: Since I'm dead set on making a setup which works, I'm now looking at what I should get in place of the 6" tube. I want to use the Celestron Evo mount, because I think the starsense and the wifi is so nice to work with. Which means I need something that can fit on the mount. Other requirements: Needs to work with the Canon 6D. Budget: £300-£900. Things I looked at: http://www.astroshop.eu/omegon-apochromatic-refractor-ap-102-714-ed-triplet-ota/p,14652#tab_bar_1_select (not a well known brand?) http://www.astroshop.eu/william-optics-apochromatic-refractor-ap-71-418-zenithstar-71-ed-ota/p,43873#tab_bar_1_select (A bit low in FL. Would prefer 600mm+) http://www.astroshop.eu/explore-scientific-apochromatic-refractor-ap-102-714-ed-alu-essential-ota/p,44837#tab_bar_1_select http://www.astroshop.eu/skywatcher-apochromatic-refractor-ap-80-600-evostar-ed-ota/p,15056#tab_bar_1_select (seems like a favorite in here) http://www.astroshop.eu/ts-optics-apochromatic-refractor-ap-102-714-ed-ota/p,51026 http://www.astroshop.eu/explore-scientific-telescope-ac-127-825-ar/p,49862#tab_bar_1_select Input by people with experience with this equipment is most welcomed.
  15. The Sony is a3000, but I just bought a Canon 6D, which is the one with the problem. But also a better camera by an order of magnitude.
