  1. As @dannybgoodesaid it is probably best to save for the mount first, as any astro photography is tricky at the best of times. However, that said images can be done with non-driven mounts, when I started earlier this year, I had a Skywatcher 200P on a static HEQ5 mount along with a canon 6D, using a high ISO (sensor sensitivity) of 6,400, I managed to obtain this image of The Orion Nebula. It is a stack of 80 1/4's exposures, stacked in Registax, this seemed to take for ever as has been mentioned previously I had to constantly adjust the scope and wait to settle, but not it was an eq mount so a little easier to follow the object as I only really had the one axis to worry about. I also managed this image of Venus using eye-piece projection, detail are equivalent focal length of the scope was some 18m (yes 18m) @ f/90, shutter speed 1/60th and the ISO 12,800, note this was a single exposure opposed to a video sequence which can then me stacked. I would imagine, that similar can be achieved with either the 550D or 600D as there was no computer control, the only other thing I had for the Orion shot was an interval timer, so I would frame the scope so as the nebula moved through the f.o.v. I would take several short exposure whilst it was close to the centre of view, then re frame and repeat. Hope this helps in your decision.

    From the album: Galaxies

    From a stack of 9 60's exposures, this wasn't the main target (comet Neowise was that), this is the first attempt, on the driven mount. I have exposure of M53 and Neowise from the 6th of August. but they will take some sifting through as a lot of cloud haze.
  3. Can I ask what equipment and how many frames. though I suspect in Bedfordshire though London might be effecting the air quality, though that depends where in Bedfordshire and where Jupiter rises in relation to those two places, at I guess I would have thought maybe looking towards Chelmsford.
  4. Thanks, my computer in the shed decided to through a wobbly, hard drive failure, so I got an ssd drive which got delayed in the post, it will help speed the old thing up a bit, but lost all last week and the back end of the previous week, drive arrived Tuesday 28th April, so just got it setup and connected to scope, still imagining software to install, but it looks like no pressing need with the forecast, and I have painting to do,
  5. Thanks. It's pretty bad I think, Upton where I life is a bortle 6 and I am on the fringe at that, but looking south is really bad, North and east are ok, north is over the house, east over houses but about 100 yards away. Thank you. I look directly over Donny to the S.E. this was merely a test to see if I could do video with the setup I have, once I got my head round a basic work flow in registax, the software did the work. Yes there was quite a bit of atmospherics that morning, I did a brief video of the moon and that was shockingly bad. Thank you, but like I said, it wasn't really an attempt, just a test, surprising how easy it was really, given the position of Jupiter relative to where I am
  6. Don't forget The Hyades located around Aldebaran, quite large though
  7. SRGB IEC61966-2.1 I think is the standard, I presume the first two are native to your laptop, you will have to forgive it a get a few things wrong, such awhile since I did this. One of my monitors, the one I am typing on is set to HP w20 LCD monitor, but has the option of SRGB IEC61966-2.1, I don't think it would make much difference but try it, you can change it back.
  8. @adam1234 Choose either Adobe or sRGB these are standard colour profiles, it is possible your monitor may have a slightly different one, if it is different try the adobe, it's what I shoot in on the camera, though it and srgb are the same in practical terms.
  9. If you want to dabble in a bit of of astro photography, the 150PDS would be a good starting point with visual in mind, you could do the same to a degree with the 150P, just photography can be a little more difficult, as I said the mount can be upgraded, though a more substantial mount would be advised if want to do photography later. If it is only visual undriven biggest dob you can afford, 6 or 8" dobs are not that large to use and could do imagery like I have shown, though not really advised as there are very few objects in the night sky you can do it on and it would really get frustrating, you really need to know what your equipment is like;y to produce, that means a good understanding in photography (sorry if you already are) You can mount a dslr to either the P or PDS version of the Sky Watchers, the PDS version is more practical for photography due the focal plane being slightly further back. P.S. glad you them, just wanted to show you don't need £1,000's just patiences and understanding of what your doing, still much to be said about old school photography.
  10. @adam1234 Hows this. adam1234_owl_nebula_ABE.tif
  11. Sky Watcher 200P with kenko 1.4 converter, Canon 6d just how the rig was set up. Southern aspect whilst pretty unobstructed from North East to ssw, there is a lot of lp. Got this a few weeks back similar direction. Only got the driven mount early March, and as you know clear skies don't happen every day
  12. I have to say though the seeing was pretty bad. looking across the valley (well not really a valley, more a depression in the ground) across Doncaster, and never having done this type of imaging before, I guess not a bad result.
  13. From the album: Planets

    Same as the details for Jupiter, this is as good as I can seem to get from the sequence, which was only 500 frames shot on the 6D
  14. Thanks Dave, still a bit of C.A. in it though, I seem to get it on the planets and the moon, not sure if it's the converters camera or barlow or an effect of the mirror possible not collimated quite right. @MarkARThanks.
  15. As we know Jupiter is fairly easy to capture even with modest equipment, but this is the first ever I have captured it using a telescope and video to stack in RegiStax, it from a 500 frame sequence shot on my Canon 6D using backyardeos, I tried the 5x digital zoom but it was a little bright (still learning software and controls, only been at this over a month). This wasn't planned I was just up late from doing some DSO's and the opportunity was there, I did Saturn as well, but it wasn't so good.
  16. Just to add I edited in photoshop, but gimp and other software will allow similar effects.
  17. From the album: Planets

    My first ever image processed in RegiStax, I captured both Jupiter and Saturn on the morning of the 12th April 2020, more by accident than design and I didn't delve into the software that much. From a 500 frame sequence, captured using my Canon 6D and EosBackYard (trial) and a Kenko 1.4x converter
  18. Ok the first is with a quick magenta filter This one with a colour balance layer, this allows highlights mid tones and shadows to be adjusted separately Both could do with a bit extra, but a pretty simple fix to a green cast.
  19. There is a basic calibration routine in windows, click start button and type display colour calibration and follow the prompts, it might take a few attempts, it also adjusted brightness contrast. There are devices you can get that do it better but not cheap.
  20. At least Venus is in the right place. I do quite a bit of P.P. work I use pixinsight and photoshop, I find even on a single image pixinsight is great for removing most L.P. but there are ways to do it photoshop gimp ect. If I am lucky I might get one more chance at this I think by the time I am 72 I will either be in my grave or not able to cope with the kit I want to image this with.
  21. Thanks I actually wanted the following day as would have fitted the scope camera set up, but the weather did as it did eight years ago, clear both days either side, cloudy the day you wanted it clear. a Kenko, it was cheap, but I does update focal length and aperture info to the exif. The overall set up though is rather soft.
  22. 300mm is a good size for the wider nebula clusters ect, like the Rosette Nebula or M45 ect, this taken on my Canon 6D would have been better on the 40D maybe, with a ef70-210 3.5-4.5 and a 1.4x converter making it just short of 300mm making it in effect a f/6.7. I mounted the set up direct on the scope, but it isn't ideal, need to get a ball and socket head for it, but most are a bigger thread. This wasn't a good image as Venus created a lot of flare, that I had to try and correct, it is because it isn't a great lens, but it 25 years old or so.
