    Hmm, i have one but i haven't used it yet,. I'm on vacation and left it at home. Will it help also with this issue? Thanks again
  2. Atreta
    Louise, I noticed that a small chunk of it is missing. There was someone who also mentioned having it in this thread, but i don't remember if he/she corrected it. Do you know how to get rid of that? Thanks

    Hey paul, thanks. Can i use the asi120mc to correct it or maybe the dslr? The finderscope is still in it's way. I sent you a reply, did you get it?

    Hi Louise, It was in north, need to check where it where that night to give precise information., but i thought if one sub was about ok, the rest should be too. The coma is really obvious, gonna try the cc when i get back home. Can't wait for the finder to arrive. Sent from my XT1069 using Tapatalk

    uranium, no, it is unguided, the 9x50 finder haven't arrived yet. the image was shot without the cc, sky was cloudy all night and about 2 a.m it cleared so i went to image a bit. i need to give the cc a go one of these days. do you have any idea about the random trails? this is how it is: the above one is ok for me, but then i get something like the one below all the time thank you.

    this is my latest attempt with the 130 pds: m45, 36x30s subs. no flats, bias or darks. i'm having an issue with my mount getting unusual tracking problem with my mount that's disheartening me, i drift align it, get some good subs with minimum trail, but then after a good one comes another one with trails, a good one and a bad one, not in order but very often. what could it be? guess i'll make a topic about it with some pictures. thanks

    thank you , uranium. no problem, you helped a lot i'll try it with the m48 to t2 and the t2 ring to see how it goes. we are in lack of astro stuff in the stores here. cheers
  8. Atreta
    forgot to say in the previous post that it did come with this adapter to t2 ring. it will still need spacers, right? i'll try to find here in brazil the adapter you mentioned, as FLO doesn't send to here.
  9. Atreta
    thanks, uranium. another thing to place in the buy list

    good news, my coma corrector and guide camera arrived today, the bad news is that(as always) it's cloudy tonight. i don't have any spacers to use with the corrector, what can i use instead? it's a gso coma corrector. btw, is there anything i can do to test both while it's clouded? thanks

    i made a post here when i tried to use the 28mm 2" eyepiece and couldn't focus. Louise told that it was needed to use the supplied 2" extension tube to focus it, and then it was ok.with the 1.25" eypieces i had no problems focusing at all, just used it with the 1.25" adapter and without the extension tube. there is a picture of it in a post i made in this topic. here is the link: http://stargazerslounge.com/topic/210593-imaging-with-the-130pds/?view=findpost&p=2600440

    that was what i meant.

    i thought about something like a micro lathe that would automatically scrape from a fixed(programmed) starting and end position. don't know if there is such a thing though. Frank

    i was going to ask how long unguided exposures could be achieved with an heq5, but your post somehow answered it for me, you must get really good PA. i was able to get 30s max, gonna try improving my drif alignment. Frank
  15. Atreta
    thanks, Jim i guess you can get a similar result, how's your LP? i'll try taking a short exposure to show how it is in here, it's ok mostly to the south and east too, but north and west is much more light polluted. please post your results when you take them. Frank
  16. Atreta
    back to the lagoon this time it was at almost the zenith and i think the LP was much lower where it was. 54x30s subs, again no calibration frames. this is a crop to cut the coma around the corners. Frank
  17. Atreta
    fantastic achievement,, tom and olly. very inspiring. Frank
  18. Atreta
    I took a visit to the site of a brazilian store and they sell this GSO coma corrector: http://agenaastro.com/gso-2-coma-corrector.html is this a good one? as you said this one won't have any reducing effect. thanks again, Frank
  19. Atreta
    Awesome picture, is it still visible?
  20. Atreta
    Thanks, i figured why it wouldn't plate solve, i tried to place the camera perpendicularly to the scope, i rotated the picture 90 degrees CW and it plate solved almost instantly. I think i'll have to buy the coma corrector sooner than i thought Frank
  21. Atreta
    This is my first attempt with the 130p-ds. I was trying to image the southern pleiades but i'm having some difficulty with the new scope as i was used to use only the camera to image with. Did a try to plate solve it with astrometry.net but it failed. here it is: 60x30s @iso 800 subs, roughly drift aligned no flats, bias, darks. Please comment what you think. Frank
  22. Atreta
    Thank you, Louise it worked with the 2" extension tube
  23. Atreta
    I gave the scope a try today with a nearby mountain here but i couldn't focus with the supplied 28mm 2" eyepiece With the 1.25" eyepieces i had i was able to focus easily, could it be because of the distance of be subject?
  24. Atreta
    Jules, Here it is Is yours different?
  25. Atreta
    Finally i mine 130pds arrived. But as always sky is cloudy and a bit of rain too. can't wait to try it out.
