  1. Another Rosette Didn't have as long as I would of liked thanks to the clouds, (seems to be a recurring event nowadays!), needs more data to get rid of that noise. Only PNGs so not Hubble quality I tried out StarNet++ for the starless image; it seems to struggle with the diffraction spikes a bit, but I quite like the result.

  2. Might be helpful if you could upload the image in question so we can have a better look. As others have suggested it might be to do with focus, exposure, trailing etc. Josh
  3. Hi Chris, To calculate focal length with a reducer, you simply multiply the native focal length by the reduction factor. For your 600mm with a .85 reducer, the new focal length would be 510mm (600*0.85) and for you 715mm and .79 reducer, ~565mm (715*0.79). Hope this helps, Josh
  4. Hi Graham, It looks like an lens flare to me; probably caused by scattered light coming from the bright moon. I'm not certain though, I'm sure others will share their insights. Josh
  5. Hi, I am going to try and sell altogether for the moment. It was very easy to set up; just mount it and plug it in
  6. For sale is my Celestron NexStar 5SE, which is in great condition; no damage apart from the usual dust. Included is the Celeston StarSense AutoAlign unit and hand controller, which makes aligning a breeze. This is in equally good condition, the lens appears smudged but the unit performs perfectly. Also includes Celestron Plössl 25mm 1.25 inch eyepiece, Celestron 1.25 inch StarDiagonal, hard case and Celestron Piggyback Mount. Happy to send via courier at buyers own risk or collection from Buckingham. Payment via PayPal or cash on collection. Will consider splitting if unab

  8. Hi there, There's a popular control system for equatorial mounts called EQMOD. This software is full of useful tools, including a 'Mosaic GoTo' mode. This will be perfect for wide field shots of large nebulae, the moon and the milky way. There's a great many guides on EQMOD, both on their website and here on SGL, that will give you info on how to use the software and its tools. Here's the link for more info: http://eq-mod.sourceforge.net/mosindex.html HTH, Josh
  9. Hi there, Because DSOs are very dim, you need to use long exposures to bring them out in images. You will be limited to very short exposures on a tripod, as it doesn’t track the constantly moving sky. This will cause your image to be blurred; at low focal lengths however this is not so apparent. Something like the Sky-Watcher Star Adventurer would allow you to take much longer exposures. With your current set up, and perhaps a light pollution filter, you may be able to do some wide field images of the Milky Way, but not much else. You can also download a planetarium software, such
  10. Ah, I was shooting at 1600. Thanks for the info, I’ll use 400 next time. Thanks, Josh
  11. Wow! Is that all from StarTools? I’ll have to experiment with it and use some of the different tools I think I’ll use longer exposures next time and a lower ISO
  12. Wow! That's cleaned it up to no end. Thanks for the advice, I'd tried denoise but I think I may of chosen the other option. Here's the link to the stack, I forgot to take flats so there may be some gradients: https://www.dropbox.com/s/vd8gfkszyhsocj8/NGC7023_32bit_tif.TIF?dl=0 Thanks again, Josh
  13. Thanks Simon, The SWCC is all in all a great corrector, it eliminates coma right to the corners. However it does act as a 0.9x reducer, which means that I have to rack in the focuser quite a long way, causing the tube to take a bite out of the stars. This really isn't a major issue and it can be easily fixed with a hacksaw, or by moving the primary up the tube. I like the 0.9x reduction as it puts the scope to 585mm at f/4.5. Some people say that it suffers with some internal reflections on bright stars (Alnitak for example), but I'm yet to find this problem as I rarely image targets cont
  14. Hi all, I received my 130PDS about a week ago as my first AP scope, and have spent the last few days getting it all set up and balanced. Last night was first light, and I decided to go for the Iris Nebula as it was high up and its size is a good fit for the 130 and my Canon DSLR. I used the StarTools free trial to process it (Hence the low resolution) as i just couldn't seem to get any decent results with Photoshop , (any ideas?).

  15. Hi there, You'll need a Canon T-Ring as you say, and also a suitable T-Adaptor; these screw into the T-Ring and then either thread onto the focuser or simply sit inside the focuser.
  16. How were you aligning? If it was just through the polarscope on your mount, remember that the reticle rotates with the R.A axis, so Polaris would have appeared to have moved if the R.A axis was not in the same place as it was initially.
  17. Thanks everyone for the responses, I’ll go for a powered hub and run it off my power tank.
  18. Thanks for the explanation, seems pretty straightforward. I’ll probably give this a go
  19. Thanks for the reply, that hub looks good; how did you power it?
  20. Hi all, I’ve just got all of my new gear for my first AP rig, but with the addition of a guiding setup, I’ve ran out of USB ports on my laptop. Because of this, I’m looking for a USB hub that I can use in the field. My understanding is that a powered one is more reliable and is a better choice than an unpowered hub. I know that the Startech one is highly regarded, but I don’t think I can warrant spending £50 on a USB hub. I was wondering if this one might work? If not I may end up going for the Startech one. Thanks in advance, Josh
  21. Setup sounds great to me The folks here are just saying that the Evoguide (whilst a superb guidescope) is overkill for the 130PDS. Most use the Sky-Watcher 9x50 finder as a guiding scope, (or other 50mm finders), which are cheaper that the Evoguide, and will still be just as good. The only thing you'll likely want to look at adding is a coma corrector, as others have mentioned, such as the Baader MPCC or the Sky-Watcher CC, but you can certainly image without one. Hope you enjoy your rig, (I've just ordered myself a 130PDS and a guiding setup), I'm positive you'll be able to
  22. I’ll try putting off assaulting my new scope for as long as I can, but I’m sure I’ll get to it
