  1. First attempt at Mars with the C9.25 and a Powermate 2.5. I think I can process it further but some artifacts are preventing me from that.
  2. I think the best advice is to show the type of images that can regularly be achieved with a DSLR and a dedicated astronomical camera so those who are new to the hobby can decide if they want to pay for the extra expense of the latter option. This is what I've done with different modified DSLR cameras over the years: canon 1000D, 450D, 600D, 100D. Nothing special, really -in fact, some can be greatly improved by a more experience hand (vignetting, noise, etc) but it gives an idea of the kind of stuff one can achieve with £200-£300 invested in a DSLR as opposed to ££££s put into a dedicated astro camera.
  3. Hi all, Just a few pictures I managed to get of the Aurora in Iceland last week.
  4. The camera was definitely modded. I think it was taken with a canon 100D, maybe 3 years ago.
  5. Looking into some old memory cards, I found this North America and Pelican nebulae that I took with a 200mm lens but I never managed to upload before. I'm thinking that perhaps the image lacks a bit of colour? Thank you for your comments.
  6. Anybody there who can help me with this? I am trying to do long exposure captures with a planetary DFK 21AU618.As colour imaging source camera. I need this for astronomical spectroscopy. I can't find any option to achieve this in the IC capture that came with the camera. Has anyone done this before or has any idea how this can be done? Any other software that lets you do this? Thank you for your help.
  7. Indeed, but I cannot see the screws; it's as if the central piece (with the Fastar label) on the center onncorrector plate with 3 sides as a propeller could be turned as a nozzle to expose them but the thing won't move.
  8. Sorry about the dumb question but I just bought the same scope and I'm completely incapable of exposing the collimation screws. How do you do that? It must be very simple, I guess, but I am putting a lot of pressure and nothing happens -I worry about breaking something. There is a ring that can be unscrewed; I would imagine that this is to remove the secondary mirror so I don't want to tamper with it. Any help, please? It's the same, exact model than it's shown here.
  9. Thank you for your comments. No astrophotos yet? Any links to sensor data: QE, noise, etc?
  10. Loads of detail in the dark clouds. Well done! you can get the subs for the core anywhere, even if it's in a light polluted area and then add them to the image. It is a really easy and quick fix. The hard bit was getting all that detail. Well done!
  11. I am thinking about purchasing an Aitk 314L + but since my experience has only been with DSLR astrophotography, I need some advice on the spacing. I understand the spacing needs to be 55mm, but at which points do I measure it? Also, I have a 2" H alpha filter that goes before the flattener. Will this change the spacing required? I want to use the camera with a SW ED80 and the SW 0.8 reducer. Finally, how do I go about attaching the 314L to canon DSLR lenses (I have the canon F2.8 200mm lens that would like to use with the ccd if possible -also with a nifty fifty)? Would I need a flattener if I use the camera with a SW200P? Thank you for your help.
  12. The 50mm was taken at F4 and it was a 5 minutes sub. The 200mm image wast taken at full aoerture( 2.8) and they were all 2 minutes subs. I can't remember the settings for the 24mm image, to be honest.
  13. These are 3 widefield images of the same area of the Milky Way taken at different focal lengths. The 24mm and 200mm photos are stacked images but the 50mm image is a single 5 minutes sub taken with a nifty fifty at F4.0. they were all taken with a canon 100D on an iOptron Skyguider in a rural location (but with some amount of light polution). I think they give an indication of the scale of the objects that can be seen during a clear night; particularly the image taken with the 50mm as this is roughly the same scale the human eye see things. For some years now, I have been using a SW200P and a 80ED on an EQ5Pro with guiding. It takes me over an hour to set up and set down. I am now discovering the joy of using a portable set up. I can't wait for the winter to image Orion! Thanks for looking and for your comments.
  14. Thank you for your kind comments. You are right Olly, I don't think focus is spot on. I also use a star in that area but with widefield lenses I struggle to tell when the focus is 200% right. I am used to Bhatinov masks where things are much easier. By the way, anyone knows where I can find a good tutorial on using star masks? I always struggle with targets like this. In this image, the Lagoon and Trifid benefitted from a little sharpening and a high pass filter but I wanted to keep the stars controlled.
  15. This is a quick processing of the galactic disc. I used a canon 100D Baader modified, a canon 200mm lens at 2.8 and a ioptron skyguider in a rural location in northern Spain. Hope you like it.
  16. Thank you very much for your kind comments. Unfortunately, even thogh the site was darker than my usual location, there was a fair amount of light pollution as it can be seen in this image. There is some light distortion asouth of Antares too. I might go and find a dark site somewhere around those hills if the weather improves. The other photo is from a stack on 7 lights with dark frames and bias calibration thus the blurred background.
  17. I am spending a few days in northern Spain and I brought the Ioptron Skyguider, the canon 100D full spectrum & Astronomik CCD clip in filter an the 24mm Rokinon lens. Well, the weather here is horrible now and it looks like November rather than August but I managed to get my first Milky Way shot last week. That´s a 2 minutes sub at ISO 800. No darks, bias or flat frames. Very little processing; just a gentle stretch and colour adjustment. I am surprised that the Lagoon Nebula is already overexposed but I have no experience whatsoever with this kind of target. There is a town (Aviles) 20 miles to the southeast so lots of light coming from there. I can´t complain, though as the sky is much darker here than in London -I can actually see the Milky Way. I want to go and find a dark site in the hills during the next clear night but I am having second thoughts as there are wolves there!
  18. Thank you pipnina. Unfortunately that doesn't seem to have solved the problem. I've tried with different computers anf different DSS versions but the problem persists.
  19. I am having lots of trouble processing some widefield Milky Way shots in DSS. At the end of the stacking process I get the usual screen for R G B wlignment but the image is white/blank without any RGB curves. I am using a canon 100D and the latests versions of DSS. Has anyone encountered this problem before? I have run out of ideas as to how to solve it. Thank you all for your help.
  20. These are wonderful images. Thank you for sharing. What aperture have you used? Thanks
  21. Thank you all for your kind comments.
  22. This is my best Jupiter so far. Taken with a SW 200Pm a 5X Powermate and a DFK 216U618 AS colour camera. The image was captured in April but I did not have the chance to processed it and upload it before. I would love to hear your comments and suggestions. It is a pity that the GRS was at the time on the other side of the planet. it is a 1 minute video taken with a fair seeing. No derotation applied (I took some 3 minute videos but I couldn't understand how the derotation software works). Thank you
  23. Excellent! Anyone in the UK watching the aurora? Apparently, there is a chance tonight even as far south as London?!
  24. Based on that analysis, wouldn't a canon 6D be superior to the sony A7S for astro work? The 6D has a very low noise and canon prouces real raw files. Also, its price is much lower.
