  1. Hi so i have a alt/az mount and a dslr which i have been able to get some basic imaging done 5 secs or so. I would to get some longer exposures. Would it be beneficial to buy a guide camera and scope? Or just not bother? I enjoy the simple setup of these mounts compared to GEM mounts, and i dont have funds for a AVX. I have had a look at wedges but thr general consensus seems to be these are a waste of time. I am aware of the field rotation you get on these mounts even if you have a guide star tracking. I have a Nexstar SE6 mount. Thanks
  2. Hi this is the first image ive taken of M13. Any tips on improving this with the kit i have please. I don't know how to reduce or remove the grainy noise, i just end up loosing stars in Photoshop.

  3. Thank you John as i plan to do the same to my D450 in the couple of days. You have brought this process down for me to 3.5hrs?? with your great write up. Looking forward to some images from you.
  4. Thanks Mick That was a educational read for me. However John was going with a full spectrum mod. I THINK im aiming to let more red spectrum through. So would i be right in saying i would only be removing LPF-2/IR cut section and leave LPF-1 in?
  5. Sorry just missed page 2 of this thread ?
  6. Hi John Lightbucket has linked me into your thread as i believe we are trying to do the same thing. I have a D450. Ive found this image thats handy and believe its only LP1 that is to be removed. I think?
  7. I found this image looks there may be 2 LP filters for the 450D that need removing.
  8. Ok i thought removing the IR filter was the idea ? I assume LP1 stands for light pollution? What is 'shimming' the chip??? And is this something i need to do?
  9. Hi all I am considering dropping the IR filters out of my DSLR which i never use for anything else but astro. Ive seen word about Astronomik clip or Badder. Im not quite what this is. Is it something i need to get to replace????? Thanks
  10. Ive been trying to workout what makes a ccd either more suitable for deep sky imaging or planetary. Is it the:- Megapixels? Chip size? Pixel size? Fps??? Cooling? Im contemplating investing in a DS camera but too sure on what specs i need to look out for??? Could anyone give me a minimum spec for a DS camera. Thank you
  11. I think i was in the same place as you are right now, 2 years ago. After owning a 8inch goto reflector i wanted something more portable that i could bring overseas. After much debate it was between a 6SE or 8SE. At the time there was about £500 difference between the 2. I chose the 6SE and spent the 500 on accessories. Lithium battery pack, focal reducer, upgrade finder scope and a wifi module. Ignoring the difference in FOV (SCT vs Reflector) there really isnt much visually between a 6 and 8. I dont believe portability is the question here so much, but how much kit you will get with the extra cash you save.
  12. Ive been looking at reviews on this and have got no idea if its worth it. I would like to avoid using a laptop. I have a alt az mount so i get around 20-30 secs of exposure at the moment no problem. Im knocking together a wedge as well to see if it helps. I know GEM is the ideal for this, but i will keep with this mount for the mo, and upgrade to a VX some time in the future. I would love to get a 1 minute exposure. Your experiences on this guider would be appreciated.
  13. So If there was a list of 5 essential specs to look out for for a entry level DSO camera, what would it be? So chip size i get this covers how much of sky you are getting. Cooling i understand. Mega pixels? What would be a minimum? Any other have to have specs? At the moment im not sure if i would have to spend £100 or £600. I wouldnt be looking for poster quality imaging, just beginner stuff above dslr capabilty. Althou i have seen dslr images that do look like hubble took them. But im sure they may have been on a 20k mount and a 20k tube.
  14. Hi all I have been looking at ccd imaging devices online. They seem to range anywhere between £70-£3000. Heres the issue, i can not find a single place that gives you a run down of what is good for what. There are some labelled as "planetary" imaging which seem to be the bottom of the price scale. Then around £300 the "planetary" description disappears. Then you have the mega pixels and chip sizes which i sort of understand and finally you have a load of graphs showing light frequency sensitivity and a bunch of other tech specs only scientists understand. Is there a dummies description to all this as i cant seem to source a good place where i can understand anything. In paticular the ZWO cameras which there are around 30 of, seem to cover a wide range of purposes but with no real guidance....you can show as many datasheets and charts as you want, if only a genius understands what it all means ,its pointless. Rant over?
  15. Why does this guy polar aligning with the tube facing the south???? Southern hemisphere?
