  1. Thanks, I didn't realise it wasn't an easy target..... I was just very brutal when it came to throwing out poor quality subs, and there was a lot of them ?
  2. I messed around for ages, the only way I could see anything resembling an image was messing about with saturation and hue levels, the image was almost black when it came into gimp....the problem is I'm left with this orange glow and if I try to get rid of it the image virtually loses all data....... to be fair they are only 15 second subs and I'm using an alt/az mount with no guiding... it's in the north sky so I have had to delete lots of star trailed subs...... maybe it would easier if I can ever get round to finishing my wedge... ?
  3. I will try that....... there are lots of people on here that recommend what NOT to do... ? ok ye I'll keep at it. Cheers
  4. Hi all. Any tips on how to pull my image though using gimp? I have the pinwheel galaxy but it's completely black apart from the odd star... it looked brighter in dss. I know the data is kind of there because when I use the auto tools such as auto white balance or auto desaturate I can quite clearly see the galaxy but it looks crap. I have messed about a bit using techniques from various books but to no avail without using the auto tools it's virtually non existant. Thanks Jon
  5. Ordered a wireless one. Little things eh!! Perfect thanks
  6. Hi all. I already have a remote control that I can press once to take a shot with my canon... when I want to take around 50 subs I don't want to be pressing the remote over and over... is there anything out there that will take that chore away for me....
  7. ok, I have since figured out that it is 51 degrees from 90 degrees, so it should be set 39 degrees from 0 degrees as I'm already at 51 degrees at my latitude
  8. So basically how I have it set up on the picture? I do have a few adjusters on the wedge... will see... the hardest part is living in England. Once a month I can see polaris ?
  9. Could someone tell me if this is the correct way to measure the angle of degrees for my wedge....do I measure it from 0 degrees (horizontal) like in the picture, or should it be measured from 90 degrees (vertical)?? I am 51 degrees from my location.
  10. I have fitted a focal reducer f/6.3 hopefully this will help
  11. Hi thanks! The wedge does have provisions for adjustments on my wedge although how accurate they are I'm yet to see as I haven't got that far yet. I used a protractor to measure the angle of latitude for myself which I drew lines on the inside of my wedge for. How accurate that is going to be is certainly the question. I suppose trial and error again. ThanKyou for replies
  12. hi guys, I have a few questions about polar alignment using my homemade wedge! I have a nexstar 8se so hopefully someone will answer who has done the same thing as me! I point the forked arm on the wedge towards north? is this a rough estimate? or am I supposed to be doing something or working something out? after putting the telescope at 90 degrees, ( by putting the two index markers opposite to each other) it asks me to put it to meridian, does this mean I do this roughly, (by eye) or am I supposed to working something out? I have only tried auto align and polar align as a trial run wthout an eyepiece, there doesnt seem like theres much room for a t adapter and dslr when it comes to how close the telescope is to the wedge! so I'm taking it as there is a limitation to what you can photograph using a wedge??? has anyone experienced this lack of room? I think I would have to auto slew the telescope to say m42 first, and then carefully attach a camera just in case it bashed into the wedge on its way round, possibly knocking out alignment! I've been reading lots about homemade wedges and not once have I heard of this which is making me think I doing something wrong also, upon polar alignment my handset hasn't instructed me to even look at Polaris, is that right?????
  13. Something was catching and stopping the motor half way round.... still not practiced alignment So much trial and error! God knows what william herschels life must have been like, I have everything virtually on a plate and I'm still struggling ?
  14. Hi no I haven't set it to equatorial on the handset as it doesn't tell me too in the manual, I will look for that. The telescope itself is now set to 0 Dec and virtually facing south. The sloping board is now facing towards north. As it slewed to go to a star on north equatorial alignment mode it nearly crashed into the wedge but I stopped it in time. Is this because it's not set to equatorial mode or something
  15. Hi guys. Im currently indoors trying out a practice polar alignment with a wedge I made yesterday. I'm pulling my hair out.. as I'm turning the azimuth left of right, it only goes so far.... then it stops. I've never noticed this before when the azimuth is level on the alt/az mount..... is this normal? The drawing in my manual is rubbish, I don't know if I have it facing the right way or not.... ?
  16. Yes Ive seen them too. I will fit one I think depending how hard this polar alignment is...
  17. Yes, it's fine, it even says in the manual to use a wedge for longer exposures... not polar aligned before but it hopefully shouldnt be too hard hopefully. Something else to learn!! last 3 months have been intense in regards to getting information in my head
  18. Do you mean you wouldn't mount the OTA? I would have thought the motors would now have less strain on them?
  19. So I made a wedge today, it's a bit fiddly in places but not that hard really if you're moderately ok with your hands. Now all I need to do is learn about polar alignment as I haven't got that far yet ?
  20. I've started to make my own wedge hopefully it will be done tomorrow.... If anyone from the UK wants to build one the bolt sizes needed for the mount and scope are imperial threads because it is built in the USA. You will need x3 bolts @ 3/8"s UNC (which means the thread is corse and not fine) And x3 bolts @ 5/16"s UNC Both at 1 and a half inch long! May save someone some hassle if you are thinking of making one
  21. Hi all. Has anyone had any experience with the celestron focal reducer on the nexstar 8" in regards to exposure times imaging DSO's . I haven't got a wedge yet but I'm hoping to extend my exposure times with this attached. I do know that this will help but I just wanted to know if anyone else has had any experience doing it. I know this mount isn't the best for imaging but it's definitely the best for me at the moment because I havent got another one ? (this mount is better than no mount) and I am gaining a lot of experience trying it out, and I'm enjoying it)
  22. Head blown off ?
  23. My view of the sky is north- northeast, I'm finding star trails after more than 20 seconds. But west or east i can do up to 45 secs, I figured if I got a wedge I could try up to 60 secs?
