  1. Ollypenrice, I am truly glad you liked my previous message. I like the minimalist approach, trying not to collect too much things... Otherwise it will never stop.
  2. Do you use a specific set of stars for each seasons? Is it possible for me to look at this PDF of yours, if it's a free one. Ah yes, I know this device, the sky quality meter. But I want to stick with rough estimations, I just feel it's not vital enough for me to spend money on, even if it's a very cool device. The total budget I am willing to spend for atmospheric studies is around 0 and 40CAD.
  3. Ahhh god.. I think you are right Stu. The field of view from my sketch is much much wider then john's AP.
  4. Hello Stu, Yes it's true I need to provide more details. With naked eye at home I can see up to around magnitude 5 or brighter. For the Pleiades, I can see 6 stars, the one I cannot see is Calaeno which is around 5.54 magnitude. For my sketch I used my Xcel-LX 2x barlow with my Xcel-LX 25mm eyepiece, 80x magnification, 60d AFOV this should be around 2700 arc seconds of sky, with my 203 x 1000 newtonian from my signature. OTHER FACTORS: - I had to draw really fast because of the mosquitoes, so the position of stars is most likely, not perfect ... but still I am confident it's far from wrong. - Also maybe the AP will show a larger nebula then what can see with 8" light gathering and human eyes, this could be an argument too... - And finally, I could be bad at positioning stars on the paper but could the Eyepiece or the telescope distort the FOV? (Just checking)
  5. I think they are an illogical purchase for the average income people simply, for me that's all there is to it.
  6. Very nice piece Mike, I never noticed the small cluster of stars close to the nebula. This is where I see the difference of total experience in this hobby. it's 2 objects in 1 sketch! Now I want to look at the nebula too.
  7. The Ethos 13mm !!! this is serious stuff. What did you preferred of the ES 14mm over the Ethos 13mm? You seemed to like the Ethos, what happened?
  8. Hello Stu, I saw all the stars from A to F with my telescope, 8 inches with a limiting magnitude of around 14 - 15 in perfect conditions. Some stars from my sketch were really faint but they were there, clearly visible, F and ? and G required averted vision not the others. (That's why they have a little line over them, they were the faintest stars I could see in the FOV) The stars on my sketch are pretty accurate with the 2 images, (It can't be a coincidence, it's too close) especially the triangle A and the optical double star G. Let's take the triangle A for instance, using John's record of magnitude, I should not even be able to see these 3, but they are clearly there, no doubt about the A triangle...
  9. Those are the days I usually get out: Thursday to Monday. I try to avoid the middle of the week because it's to hard to restore my sleep from there (unless I am full of energy after 1 week of rain). I have an espresso machine and drink only a small sip of espresso coffee just before the observation, like 1/3 of a tiny espresso cup. this will keep me up for 1 hour.
  10. This is a new image of my sketch along with another picture I found. The match from what I saw is not bad, better then expected.. my telescope is supposed to be limitated at magnitude 15 and the stars from A and G are accurate for sure. There is something wrong.
  11. Interesting report thanks for sharing it. Has for me, my first stem was a semi-failure, this is my sketch of the stars surrounding the Ring Nebula, but my stars aren't at the same place has the existing recordings. Although, it could be a code 18.. these stars from my sketch were so faint, I could see them only with averted vision, invisible most of the time and maybe like you Nyctimene, visible 20% of the time. I used 80x magnification to produce my sketch xcel lx 25mm 60d AFOV. Still an interesting exercise. Update #3 - After a few rotation it makes more sense, some faint stars match the recordings. I don't have time to study the images further..
  12. The governments act has if it's useless to live on earth but do we need to leave that bad? If we don't need to leave, I would stop investments on Mars and invest in developing cleaner energies on earth, like the ITER project and studying to create new and incredible elements to help us explore space. If it could be easy like this (: https://www.youtube.com/watch?v=xaVgRj2e5_s
  13. Boinc and SETI great memories! After 1.5 years of crunching data, my computer died. Cheap 75$ MSI motherboard..
  14. I notice during summer after a few days of rain, really high temperature during the day, ambient hot air packed with humidity and a drop of temperature at night, dew will deposit on the gear. Hot air can retain more humidity then colder air. I just look at the humidity forecast for the night, at around 70% and more, I know there will be dew to deal with. I keep my eyepieces inside a box with a cover during the observation. You can read about the dew point too. http://www.calculator.net/dew-point-calculator.html And this the psychrometric chart, I don't fully understand how to use it but I know it has the answers to many question regarding air, humidity, temperature, pressure etc. http://www.coolerado.com/pdfs/Psychrmtrcs/0000Psych11x17US_SI.pdf ============ In the house, I let the telescope and eyepieces dry in a dry room, remove the caps and put a tissue over the opening it to prevent dust from getting in and a tissue over my EPs box. Next morning I put the caps back on, close the bag and EPs box with silica gel inside. Never had any problems so far.. if this can help.
  15. Really interesting this topic, thanks John for sharing the ring nebula image with it's surrounding stars. On my next observation I'll sketch the entire FOV, picking the faintest stars possible. Then I will compare with your image and Stellatium. Great exercise! Hello Gerry!
