@@gamerdaddy8597 can't help you if you don't tell what you are imaging with. ie camera, telescope and if you have a tracking mount.Can you report back?

@@VillainTheHammer that was my initials at the end of the video. Not before Christ. And the year it was filmed.

Thankyou. I do have quite a few other Moon and space videos on my UA-cam site. You can easily view them on my Screedy site.

Gracias y saludos

No. I've not been allowed to buy anymore astro gear by my wife. Besides the Vespera I had to buy an iPad with lots of memory and Sim card capabilities. So that was an extra $1200.

I’m from Ireland and want to get into it too, looking into getting the vespera 2 as well. I was in Perth earlier this year as I was going to try live there, unfortunately didn’t work out without a proper qualification for a career! But Perth is amazing, I can’t wait to go back! Amazing pictures!

​@@ImmAaronnyou will probably not get the best out of any astrophotography capable telescope in Ireland. You need to get at least 30 minutes of clear skies to take long exposures. Best to buy the much cheaper Seestar 50 smart scope and a dobsonion for viewing. Consider the clouds eh.

@@screedy1050 good point, I will probably have to re-consider that. I’d love to get into it but unfortunately I’m very limited in my country haha

Thanks

With a standard 25 mm eyepiece the magnification with the 1200 mm long reflector scope is 48 times. The DSLR on prime focus brings it just a little bit closer. So it probably gives about 52 times magnification. The close ups you see of the moon in the video were just cropped sections of the images taken at prime. You can also add a Barlow lense to bring it all closer. But the DSLR is no good for planets. You need a planetary zwo camera for them which have much smaller sensors.

Thanks for your immediate and helpful reply! Well I actually plan to use the dslr with barlow as adaptor/extender, so no eyepiece. In that case what is the sensor equivalent to? Note that it is a standard 4/3 sensor

If you used a two times Barlow it should give you at least 96 times magnification. A 3 times Barlow would likely be 144 times. I wouldn't recommend anything stronger than a 2.5 times Barlow. Also once you add a Barlow the view is much dimmer, and you have to jack the iso up a lot,which introduces noise. Also a Barlow is hopeless for stars and nebulas. You are best to go with prime focus and start with the moon. A Barlow will disappoint.

Thanks again @ Screedy!

Just lense flare from the sun.

Thankyou for your question. I have checked my star chart and cannot be certain which stars they are. Lesser stars are given numbers. There are 2 in the same vicinity as alpha Centauri in my photographs. One is named HD129992 and the other is V1036. But I can't be certain if that's them. It's impossible to see any planets beyond Pluto with a small telescope. They are light years away. The coloured dots you see are just two, of billions of stars in our galaxy. Some stars exhibit different colours than white,due to their temperature. The red,orange and yellow ones certainly catch your eye when viewed through a telescope and even binoculars.

I have no idea of what your level of knowledge is, or what telescope you are using, so will give you the basic tips. First of all you must set the camera to Manuel mode. Practice getting focus during the daytime on a distant object. You will get best focus by using zoom on the camera and fine tuning the telescopes knob. Take some images after getting best focus. If the resulting images are too dark or too bright, you have to adjust the exposure and iso settings till it's right. The F setting is not relevent when connected to a telescope,so no need to adjust that. Then at night practice on the moon. Because it is so bright you only need an iso of 100 and an exposure of one 320th of a second. But that's too dark for the stars, so you need to increase the iso for them up to 1600 and use longer exposures of at least 1 tenth of a second. If you use a 1 second exposure you can reduce the iso to 400 which will reduce noise. Longer exposures will result in star trails though.Good luck

In the view at 1.59 we are seeing the earth in the distance. It looks like a crescent due to the view from Artemis. All are facing the sun on the right in the scene. The reddish oval shape is just lense flare caused by the suns light on the glass and then the cameras sensor.

The telescope effectively becomes the lense for the camera sir. The eyepiece focuses on the mirror inside the telescope. Just the same the camera focuses on the same mirror. But the focus for the camera has to be adjusted by the focus adjustment fitted to the telescope.

@@screedy1050 Thanks very much, I've got a similar camera and the same telescope, just bought the t ring and spacer , can't wait now to try it all out , sorry I just thought the telescope eyepiece gave you the magnification. 👍👍

@@Kemagic once you connect the camera to the telescope, you have to switch the mode on your camera to Manuel. You will not get a view through the scope on any other camera setting. Practise with it on a distant object during the day first. Getting the iso and exposure setting will be completely different between day and night though. For the moon you need an iso of 100 only. And an exposure of one 320th of a second. The f ratio does not come into it.

@@screedy1050 Brilliant, thank you again, I can't wait to try it all out, your images are fantastic the best I've seen. 👌👌

@@Kemagic I recommend you join the Dobsonion astrophotography Facebook group. People there can answer your questions and you can share your photos there.

Thank you! Cheers! Tell me what you think of my latest video of the re entry.

The cameras transmitting the picture and videos is not a sophisticated camera, pretty low resolution because of limited bandwidth. The craft will bring back high resolution video and pictures. Would like to see your pictures of the far side of the Moon.

We definitely went to the moon.And on several different occassions. The astronauts encountered huge problems with the moons fine dust. They were in danger of their suits being destroyed by the effect of the dust. It limits the time that they can stay on the surface. NASA has been working on a solution to the huge problems for years. There's no point sending people there if they can only stay for a limited number of hours. But they have now come up with a solution.

It's explained in the description sir.

I doubt it. Betelgeuse is 642 light years away from us. Multiply that by 186,000 miles per second,and its an incredible distance from us.

Goodbye to one of the brightest star 😭

lmao how orion gonna hold his skin 💀

Yes

We would have detected gravitational waves or neutrinos long before photons would be seen

@@jay2id yes, but what if it happened before we had those technologies?

@@darelcream supernovas are not an overnight event. they last a very long time in regards to our perception of time. we would be actively detecting neutrinos and quantum particle fluctuations that could possibly be easily traced back to a betelgeuse supernovae event. this would be the case if it already happened- because supernova last a long time.

The description verifies which images I took with my skywatcher 10 inch dobsonion and the Nikon 5600.The 2 dots were captured at 1 thousandth of a second and an iso of 1250.

UA-cam is not like an astrophotography group,where you are expected to verify the equipment,, and the techniques used to obtain the image or videos. You can tell fibs on UA-cam and get away with it with impunity.

@@screedy1050 No of course not, but I was curious. I have a 10 inch Meade Starfinder on a dob mount, (I bet your optics are in better shape than mine), and a Meade Starfinder 16 inches on a German equatorial mount. I'm tempted to get a camera like that 5600, and play around with it some. Clear skies.

@@daveblackford6097 if you don't already have a camera for imaging I would recommend the zwo 224 mc planetary camera as well as the highly rated Nikon 5600. And you can see all things dobsonion on the " Dobsonion astrophotography" Facebook group.

So have you actually seen this phenomenon through a decent 🔭? Notice that the image is not affected by the atmosphere.

@@screedy1050 I've had my own telescopes for over 25 years, I've more than seen it, along with every other amateur astronomer I've spent any time with, when the wind picks up we don't even bother setting up the Scopes. BTW I'd hardly call it a phenomenon. It's a simple well understood effect. This is what adaptive optics are for, and it is available to the amateur astronomy community.

@@daveblackford6097 I was wondering when an astronomy nerd would actually make comment about my video. It was not windy at ground level when I filmed that.Its obviously upper level air movement. I usually only get a couple of dozen views of my astro you tube videos. So have been astonished at all the interest in this one.

@@screedy1050 It's still cool footage of the star. What kind of scope and camera did you use?

@@daveblackford6097 I listed them in the description of the video.
