  1. Managed to get one pic in between the showers yesterday, seeing was dreadful, had one break in the clouds/showers legged it out with all the gear. Extremely overexposed to pick up Saturn but that was it before the clouds came again! Setup 250p with QHY5L-IIC on NEQ6. Anyway happy to get a shot with them both in the same field of view, this country's weather absolutely stinks for astro events. Happy Days
  2. My friend you are a genius, worked like a treat. Many thanks for your help
  3. Hi Got out the other night for the first time in ages. Managed to get some potentially good vids of Mars, however can't remember for the life of me how to use pipp correctly. When I first load in my vid I get this- Then I change the quality setting to reorder the frames in qualitiy order, next I go to processing tab to object detection & select center the object in each frame so I can use it in autostakke. But no matter what settings I put it on I get this at the end Dont know what I'm doing wrong but its really frustrating as I used to use this software all the time in the past. Any help would be great thanks.
  4. Really interesting As I understand it (according to my optician) astigmatism means your cornea is a little cone shaped rather than curved as normal. I suppose it will probably get worse the older we get! thanks for the comment
  5. Thanks for all your comments. Probably a silly question but does having an astigmatism mean that the object I'm viewing would be slightly blurred? My eye prescription is R -5.50/-0.25 30.0 & L -4.75/0.75 40.0 Not to sure which one of those figures describes the astigmatism although I was told it is mild. I've always just used contact lenses (hard gas permeable) when viewing so I presume they don't correct the astigmatism only wearing my glasses will is that right?
  6. Quick question I've been thinking about for a while- I'm short sighted & I have a slight astigmatism in both eyes (awful eyesight!). I normally wear contact lenses but have (thick lensed!)glasses to. So my question is when observing through a telescope will my astigmatism effect the image I'm seeing? Also would it be best to view with contacts, glasses or without either? thanks yelsac
  7. Hi I've had a couple of 450d's & I have to be honest the mini usb connector is notoriously weak! I had exactly what you are describing an intermittent connection. In the end both of mine gradually separated from the main motherboard, I had to move over to one of these http://www.ebay.co.uk/itm/Timer-Remote-Control-Shutter-Release-For-Canon-600D-60D-550D-500D-450D-700D-70D-/112453258280?hash=item1a2ebc8c28:g:Rg4AAOSwyWZZTIey
  8. Yes I think my son put a light on! but its not a massively bright light so shouldn't effect the setup except I noticed the DSLR was pointing back towards the house! I was just wondering if anyone else had experienced this & if indeed its the DSLR's viewfinder causing it
  9. Hi Can anyone tell me why I've got this funny stray light on some of my subs??? I've got a great big dew shield on my scope which is pointed heavenward, most of my subs are ok but I have a few that have this strange shaped orange light at the top end of the picture. The only thing I could think of is maybe some light is getting in via the DSLR itself. Could this happen? Is it coming through the DSLR's viewfinder or something? If so any ideas how to stop it? Sorry so many questions but after struggling for over an hour to sort a problem with setup I was pulling my hair out anyway & then this GGGRRRrrrr!
  10. Just had a look at some of your pics wow!!!! totally awesome. Probably a stupid question but you said you don't use dark's by using dithering but do you use flats or bias frames?
  11. Hi Thanks for the reply I set the dithering distance to 3 in APT & also raised the scale in PHD2 to 2.0. I can certainly see the difference between subs(they do move around). Am I right in thinking that if the dithering is done right there is no need to take any darks at all? Mind you not sure how I'd know the dithering was moving enough! I'll have to keep an eye on the Settle time to, at the moment its set to 15. thanks again for your advice
  12. Just a quick question What settings do you guys (the experts) use in the APT guiding section for dithering when filming with a DSLR? I use good old PHD2 with a guidecam. I really want to know how much of a dither is required to get the desired effect. thanks
