  3. Hi Everyone.

    Just thought I'd share my first ever image of M42 and say thank you to everyone who helped me out on here.

    I had so many troubles with my mount and after using the help provided from this site, I can confirm the mount is working like a charm, finally.

    This is a single 240 sec exposure of M42 with an un-modded Canon 6D, no guiding, no stacking...I'm so happy.

    I now have to learn to auto guide with PHD 2....so you'll be hearing from me soon.

    Thank you all

      Not an imager, so can’t critique it in that way, except to say very nice for a first image. Well done! :)

      Thanks for that Knighty2112, really kind of you to leave a comment, cheers.

  4. I'm really taken back at how amazing everyone has been in helping me. I thought no-one would reply and instead loads of lovely people I have never met have tried to help me. Thank you all...I really mean it...in fact there are so many posts I'm not sure who I've thanked...so this ones for all of you! Thank you!!!!!!!!!!! I'm going to give all your suggestions a go over the long Weekend
  5. Platesolving...oh my.......maybe in a bit...what is that lol? I will look it up online. Thank you for confirming the dust issue...i was pretty sure my camera had a non-reversable problem and I was pretty heartbroken.I thought it might be an issue with the sensor over heating and I was going to get this every time...phew. It's so amazing when people on here can confirm what the issue is so quickly and put my mind to rest..your a star. Thank you!
  6. Ah I see, the sky is divided up onto regions..i didn't realise that! I have also not heard of PAE...i'll check that out.Also I have not seen the PA optiion after 2 star alignment..maybe that is not on my handset as I have the older non-updatable v2.04 Skyscan handset...but I will check. Yes I do defocus the stars when I align. Thanks for your help Year of the Goat...all your help is amazing....but your name is even better! I have a goat in trees calander...i think you need to get one...http://www.saltartists.com/goats-on-trees/
  7. Thanks Steve. Ah yes..i did do that a couple of times but that's why I chose Alkaid and Betelgeuse because I know them very well. I'm going to choose some new ones next to continue my GOTO issue investigation.Actually I think the hardest part of setting up at first is the star align. Your just left there after doing everything, looking up at all those stars thinking...errrrr where the hell is bloody MIRZAM!!!! Although..i do use Stellarium to locate the stars I don't know. I would never trust doing a star alignment through a camera...maybe if i had a good CCD I would. I always do alignment with an eyepiece before I pop the camera on..Then goto a bright object such as the moon, planet or visible cluster far away from my alignment stars, like M44 thats in the south (in realtion to Alkaid) to check the GOTO accurracy. If the GOTO looks good and the subjects in the middle of the viewfinder then I attach the camera and go after the obscure DSO's that I can't see through the scope but a long exposure can detect. I'm sure the issue is simple...it's just figuring out which part of the chain I'm messing up......your help is amazing thank you mate.
  8. Really appreciate this LightBucket...this is really the help I needed.I have been overlooking PA and concentrating on Levelling the mount...star aligning/co-ordinates etc. What you say makes perfect sense..i assumed the GOTO was not so reliant on the PA...so thank you! By the way...Do you have any theories for why my 1 star alignment is giving me better results than my 2 star??? I used Alkaid (*1) and Betelgeuse (*2) for the 2 star alignment. Using 2 stars M51 was on the side of My 6D frame, chopped in half....M101 was way over to the left of the frame...off on Jupiter and moon in the east. I used Alkaid for the one star on the same night.Subjects near Alkaid (the images from my post) were bang on, so was the moon and Jupiter?M82 was a bit off but still caught it in the frame as you can see from the picture.
  9. Thank you Steve. My images were taken at roughly 120secs so 2mins each I think. I really did not realize that PA was so important for the GOTO side of things.I know it is for imaging I have tried to get good PA but as I assumed that for the GOTO to work well I did not need accurate PA I have not concentrated on PA it as much as other things so that's where I will concentrate my efforts from now on. That's a great tip about getting a star in the eyepiece with the mount tracking in sidereal rate.I will try this. Thank you
  10. Thank you all for replying...i'm still trying to get my replies to you all in some sort of correct order. It means a lot to me that you have all taken the time to post your ideas and help me out, keep them coming and thank you all so much!!
  11. Ah Thank you so much for confirming that this is dust on the sensor D4N. I hoped it was dust, as you say it seems to have moved along the frame because I have sensor cleaning on, I have never seen it before so i was a bit worried that my camera had an issue. Ok..I didn't realize that GOTO was so dependant on PA. I will spend then next few nights perfecting this and see GOTO improves. Many thanks for responding.I can't thank you enough for helping me!
  12. Hello. I was hoping someone might be able to help me??? This is my first post, so first off I just want to say a big "hello" to everyone here at Stargazers Lounge. My equipment is: Skywatcher ED 80 + FF/HEQ5/V2.04 Skyscan handcontroller/Tracer 12v battery/Canon 6D, I am not guiding or using a PC. My issue is......I can't get the GOTO function to work perfectly. My HEQ5 GOTO keeps on missing its target everywhere when I do a 2 star alignment. The target is just outside the field of view using a ED80 and 28mm eyepiece. When I do a 1 star alignment I seem to get much better GOTO results but start missing targets when I move further away from the star 1 used for alignment. I have done all the basics...I have callibrated the polar scope, levelled mount, entered correct info into the controller (date in US/Co-ordinates in hrs+mins) Polar aligned ok, tightened Dec and RA bolts and made sure HEQ5 is in home position before turning on the power, tried to centre the star when aligning etc. A few things I noticed over 3 nights of using my HEQ5 were: Night 1) Tried a few two star alignments with Alkaid and Betelgeuse but i found that the Goto was off on Jupiter and the moon in the East. I could see the light of the moon through the telescope but had to the center using the handset. Same issue with Jupiter.Tried again from scratch 3 times but always the same result. I used the same alignment stars because I'm not so sure on others yet apart from the obvious and some of those were not on the list the skyscan controller gave me.I gave up on the goto in the end and just looked at Jupiter and the moon for a few hours....they were superb, I was amazed at how far I could push Jupiter with the ED80, almost better than my 200p in ways.I can see why people like refractors! Night 2)Set the mount up. Tried the same 2 stars and got the same result.However this time I tried some targets to the West in Auriga without thinking about it and the Goto seemed more accurate????Is this because I aligned with Alcaid near the North and Betelgeuse in the West, therefore it tracks better in the Western side of the Meridian? Night 3) I then tried out a 1 star alignment just to see what the difference would be (I used Alkaid) I can get M51 and M101 bang in the centre of my Canon 6D but M81/82 start to appear to the top left corner and not in the centre....the tracking seems to be going off the further I move away from my alignment star.I then chose M44 in Cancer because it is to the South and it was off in the frame to the left, like the 2 star alignment was giving me......I assumed though that maybe this is the case with one star alignment, it can cope in an area near the alignment star but as you move further away it gets worse???? Using the 1 star alignment gave me a chance to do a bit of imaging for the first time so I stuck with that. I have not tried 3 star alignment yet and I know that this helps compensate for cone error...I will be trying this next anyway to see what I get. Is there a way to get the Goto to work on targets all over the Sky? Do most imagers just choose a star near the area of sky they want to image in and use the 1 star alignment?? For visual I thought the 2 star alignment should work but to be honest the 1 star was better!! I would really like to get the GOTO to work on any target i choose wherever it is in the sky. Anyway I've just started so I have a lot to try and experiment with but I thought I would try some suggestions here because I might be missing something obvious? Any help would be fantastic Thank you and clear skies to all. PS.I have included 3 pics to show how the first 2 targets are central but the third is starting to go amiss.They are also my first ever Images so thought I would share. If anyone knows what those black marks are on my images any advice to get rid of them would be really usefull...looks like something on the sensor...or from deep outer space..lol.
