  1. Hi All, Well had my first attempt at widefield with a DSLR the other night. All because of this article in the register... http://www.theregister.co.uk/2015/08/04/nearby_exoplanets_circle_nakedeyevisible_star/ Not sure why I felt compelled to image it, perhaps there is something magical about looking at a star and *knowing* it has planets rather than wondering if it does. Anyways I'm glad I did because I had a lot of fun.. its been too long since i last spent some quality time out in the garden. The set up was a bit precarious to say the least... i set the 3-2 up and polar aligned as usual
  2. On the Bahtinov, it works on jupiters moons too. Though im using the ASI when i do it, I see no reason it would't work with a DSLR, couple of sec exposure, max iso ought to do it. Once you find where the focus is, a pencil line on the focuser tube will get you close next time. Cheers Mark
  3. Hi Roger, Its an excellent tutorial mate, very easy to follow and im chuffed with the results. Nice colour scheme too, feels very natural unlike my previous attempts Appreciate the time you put into it, just another reason why the SGL community is so special. Cheers Mark
  4. Chucking it down all day today, i hope the summer isnt over yet Worked through Rogers tutorial after dinner tonight. Had a lot of fun with this though registax 5 was being a bit temperamental and throwing out of memory and floating point errors. But i was throwing tiffs at it. Though it was fine with jpg's. Stacking worked well, ive never used the ROI feature before so that was good to learn too. Thanks again guys, see you on the solar section. Cheers Mark
  5. Thanks for the tutorial David. I'll have a read after dinner. Sure was a strange experience seeing my garden in the daytime Cheers Mark
  6. Well its 1200mm on an eq 3-2. Most of the problem is wind i think. The PL is essentially a huge wind sail and it generates enough torque to flex the eq head. Also any vibration such as walking near the scope ruins subs too. Balance is also an issue, particularly near the zenith as i have to be very careful not to let the ota bang into the mount legs, so that sometimes means not being as balanced as i would like. Not knocking it though, its great visual and planetary it will hold the target in a 300px box quite happily. When i first got my polar scope i thought i was getting 60sec, but on clos
  7. Baader solar film arrived during the week and I got some time today to make the filter cell. Armed with an assortment of cardboard, glue, packing tape and double sided sticky tape i set too. Organised chaos at the dining room table but the end result. One snug fitting, sturdy, full aperture solar filter. And it was sunny outside to boot. One thing i did forget though, laptop screens are hard to see in sunshine. So i stuck the laptop in a large cardboard box and stuck my head in there too, which made focusing pretty awkward. Some sort of telescope screen required i think I had been curious ab
  8. Hi Jd, THREE SUBS!!! out of 217 I think i get 3 that are good, 30% junk and the rest... well i'd rather junk em but then i'd have nothing The move to a more stable platform is going to be very welcome indeed I dont think thats an exaggeration, check out this site: http://www.pbase.com/samirkharusi/image/37608572 He has a lot of other great articles too. I need to re-read this, i read a ton of stuff like this when its cloudy, but promptly forget it all when the dust cap comes off. I remember trying to figure out the sky glow using his method, but the clouds appeared. Based on slightly dod
  9. Yep got you on that. I actually used iso1600 on the ring. Im usually 800, but transparency was good and the test at 1600 seemed ok, so i went for it. Hopefully it will be ok tonight, going to gave a proper go at drift alignment. If i can push it up to 30sec then i'll be chuffed.
  10. Wow thats a cracking image you got there Jd! Those colours are amazing!! Did you use a modded DSLR along with the CLS for that? Or is this the cls coupled with longer integration? Whats amazing is that you did this at 2.7m and got great results using 30sec subs. This is all very encouraging. How are you finding the eq6 at that FL, are you loosing many subs or is it just a few here and there? Cheers Mark
  11. Thanks again for the processing advice Olly, I'll be brushing up on my ps skills then, starting with the selection tools for one and no more blanket sharpens either! Best thing is, i can go back to all the other things i've imaged and apply what i've learned to them too. A definite win win situation Cheers for that! Im constantly surprised by whats possible in heavy LP. Looking up at that orange/purple sky with its 20 or so visible stars you would be tempted just to go back inside and watch tv or whatever. Sticking an EP in doesnt help much for fuzzies, 45min looking at M1 and not seeing it
  12. That makes sense, dunno why i thought i would get longer. Though in theory i wont have to throw away so many subs which is good. Looks like i'll have to go down the guiding route earlier than expected. But have the ASI cam so can try the finder scope method maybe. More stuff to research I did take a look at the DARV method actually, I like the idea of it but yes it does seem like a fiddle and more time away from getting subs. Having said that, if im throwing away half my subs and not happy with the other half then its not time wasted. Cheers Mark
  13. Thanks for your kind comments guys! Olly, thanks for the processing advice! Ive now reprocessed it, hopefully i got it right. I aligned the channels in the histogram just using the black point. Background wasnt near 23 so then i made adjustments to the mid point until the 11x11 sample was around 23 in all channels for the area i intended to crop. BIt of despeckle and unsharp mask. Cropped then reduced by 50%. Seem to be getting a lot of colour noise so maybe i stretched it too far? Anyways it doesn't look red now. Very dark in laptop but ok on my monitor. Really need to download one of those c
  14. Thanks Guys,Yes! I believe the centre star is in fact the one that caused that lovely display. Just a little hot core giving off a lot of energy. Seem to remember something bout square laws and surface area vs luminosity or something. So i guess it must be really hot, or perhaps not that far away. I really should research my targets more No light pollution filter. Have considered a cls clip but that would require longer exposures which i probably wouldnt achieve. I dont have any direct light pollution though just sky glow. Now that ive sorted out the flats ( before they were destroying my dat
  15. Quick process of Saturday nights attempt at the ring nebula. Turned out to be fairly easy to find though i could only get a hint that something was in the EP. A quick exposure at max iso revealed that i was dead on target ( for once ). It was smaller than i expected, almost tempting to barlow it, but not with my setup This was about 18min integration, 56 x 20sec iso 1600, 30 dark, 30 bias, 20 flat, 20 dark flats. I think i must have nudged / upset the polar finder alignment because i really struggled to get even 20 sec without some trailing, and even with that the stars arn't as round as i
