  1. Hi guys im outside now on what is the clearest night ive had in months, Im trying to photograph the moon, with my dslr attached using a dslr ring to my 10 inch dob telescope. Simple question, how on earth do i get it to focus?! I point the scope at the moon, look at my camera display and just see a blurred bright white circle. Ive adjusted ISO to about 200, and shutter speed is about 1/500 PLEASE HELP!
  2. I dont think it is when i take a dark image, seeing as i couldnt find many in the other shots of the sky i took. Ill give it a go though. Sorry I cant remember, I wasnt taking a picture of a specific constellation with this shot, I was just experimenting with the settings etc, all I can remember is that it was approximately to the east at about 9pm, somewhere between ursa major and orion lol, obviously thats not helpful because thats half of the sky I think it could have been near leo?
  3. hi thanks for replying, this was quite a while ago but I believe i was only on about 25-30 second exposures, about 2000-4000 ISO. This seems to be the only image I actually took of that patch of sky, I think I found one "purple thing" on another image but thats about it, it's just this image with the one marked, the 2 to the left of the image, and the one top left.
  4. Hi guys Today I was looking through some of my images i took of the night sky a few months back. These images were simply done by putting my camera on a small tripod (i think it was a cleaning tripod because i didnt own a full size one at the time) and then changing some settings and then firing away. Looking at one of my images, (attached) i zoomed in, because as im sure you know if you zoom in you can actually reveal some things you couldnt normally see like a distant star etc. Well i zoomed in and scanned around the image, and on the left side i saw a purple dot, I have outlined where i sa
  5. just so you all know the actual full moon is tomorow, it is 93% tonight in its waxing gibous phase. It will be 99% tomorow. Just some info lol
  6. Brian Cox was on BBCR2 on Friday. Just some info: His new series wonders of the universe should be on screen sometime in march. Also some really impressive info... after Stargazing live: Telescope sales have risen by 50% and applications for physics degrees have risen by 40%. That is just amazing What do you guys think? Sammy
  7. Hi Before you start yes i know astrophotography doesnt work with dobs, i do know but i want to try and im mostly going to take images of the moon and videos of the moon and planets which i think is possible because of the light thrown off of them so wont need high exposures. Anyway i have the t adaptor and t mount for my canon Eos 7d. Went out tonight for the first clear night ive had in weeks and god it was just amazing. But i tried to use the camera mounted on the scope and nothing, i had it set to aboout 30" which is the lowest shutter speed i can get, i think it was 3.5 aperture to start w
  8. It is more than 47 billion lt years i believe. I heard that at the moment the diameter its about 156 billion lt years. There is an edge to the universe but it is constantly moving because of the expansion of space time. And no its not 500 million years more. 13.7 billion years ago was when the expansion began, this was calculated firstly using Hubbles graph of veloctity/distance of observed galaxies. He found that as you increase the distance, you increase the velocity to the velocity of the galaxy is directly proportional to the distance. Anyway, within that 13.7 billion years, space time ha
  9. Hi My accesory list is building with a few EP's and some other stuff and i plan to buy other things such as filters etc. Basically i need something to store them in but i havent got anything at home, needs to be quite big, durable and secure so nothing breaks. Ive looked around and the only thing ive found was an actually accesory kit from Celestrong which comes with EP's filters etc in an aluminium case and this is for around £130. I dont want a kit but i really need a case, i like the looks of aluminum cases but where and what? If someone has any suggestions id be grateful. Thanks
  10. sorry for the lack of info. I keep me scope in the extension (isnt having anything done to it so not a problem), its relatively cold in there. My packing up procedure is to carry it back in, cover it up using the caps etc both the finder scope, eyepiece holding part and the main tube. Then i put this old sheet over the top of it to ensure that dust doesnt get to it etc.
  11. Hi Firstly i was wandering, say you go out on a cold night, dew builds up on the primary mirror but you dont notice so store it away and leave it. Is that bad i mean, can it do damage to the mirror? Will it have that much of an effect of the thing you are seeing? Basically im asking this because i am worried. My collimator just arrived so i collimated my scope. But when i looked at the primary it looked odd. Basically it has lines across it, not straight lines and not scratches. They look like frost? It still gives a perfect reflection etc and doesnt seem to have any effect. I have only just n
  12. thanks guys, no i dont have turn left at orion. Forgot to mention i have Stellarium though lol. Im out in the countryside so i get pretty good skies apart from to the south which is towards the city there is very very slight pollution. I guess ill just have to keep trying Oh do you guys think i should get some filters, im going to get a moon filter so i dont get blinded again but i was wandering about other filters like for planets etc. I was looking at jupiter yesterday through my 6mm, it was clear and i could see the band easily but it was quite bright, will a filter help? Also i want to g
  13. Hi guys As a few of you know i bought a skywatcher skyliner 250px dob recently. I have been putting it to good use but of course the weather hasnt been great. Last night however was simply amazing, perfectly clear no moon to ruin deep sky stuff. I saw a few new things but accidently well one was an accidental galaxy i think the other was sort of on purpose because i saw a smudge in Gemini and then found a smaller smudge in that smudge (the first smudge was just faint stars) which was a very large cluster, with sooo many stars in it. Anyway the point in this thread is that i am struggling. I
  14. neptune wont be the same size because it is further away. Not sure that it is actually visable? i highly doubt you will be able to locate it with ease through your scope.
