Background info: I have 2 scopes a nexstar 6se (150mm aperture and 1500mm focal length - f10) and a evostar 72ed (72mm aperture, 420mm focal length - f5.8).
I haven't had chance to use the evostar yet thanks to the clouds. 😡
Question: Does the f5.8 mean I'm going to be able to reduce my exposure time or is it cancelled out by the fact the aperture is so much smaller?
I'm fairly new and on one of my daily stargazing sessions I viewed, with the naked eye, a huge passing light going SE, from my perspective it was brighter and bigger than any stars, planets or meteors that I've seen before. It was roughly the size of a baseball.
If this was a star -> .
this is roughly how big it looked -> O
It had a trail of similar size, seemingly dusty. It also passed and disappeared between Corona Borealis and one of Hercules' legs.
Viewed on May 16th, 22:00- 23:40
I assumed, based on recent headlines, that it was Comet Swan, but upon further investigation, that was far from true.
Comet Swan should not be visible with the naked eye, and definitely not to the degree I saw. Additionally, based on my coordinates* it wouldn't even cross the sky I saw, it would be below the horizon.
(*roughly 15 °N, 120 °E, PH)
Considering again the magnitude of the object amd the fact that I viewed it with the naked eye discounts it from being an asteroid or meteor*.
(*More possible but still hard to believe with its size, you wouldn't even see something like that during meteor showers)
So I then researched if it could be space debris. I thought that something as big as that should be covered by a news article somewhere.
*The only results were of the 18 ton Chinese Rocket but it couldn't be that because:
A. It passed over Los Angeles and New York then fell into the Atlantic Ocean, with some pieces landing in Africa. Meaning it wouldn't pass over my country.
B. That happened 5 days before my viewing, on May 11 at 11:33 AM ET (08:33 PDT)
It's still possible but it just seems unlikely, and with how big it was I'd assume that it would attract some media attention but I cant find anything else.
Does anyone have any idea what it could have been? I have to know. If it was debris then all I need is confirmation.
Hello stargazers, welcome. I had posted a picture yesterday of Uranus that had appeared to show its rings. I am using a Nexstar 4se, a 2x Barlow, and my Neximage Burst Color and capturing hundreds of photos and stacking them for my results. But still had me and others curious to if I were actually seeing the rings of Uranus or maybe just a glare of some sort.
So I got back out there this morning, might I note I live in FL where the weather tends to stay hot so clear imaging during this time of year can be difficult, but not impossible as this image that I stacked 150 out of 300 images taken may show that statement holds true..............or I could just be mistaken the object in the image, but all in all I am feeling pretty confident that I have a decently clear image(stacked 150 images) of Uranus, its rings, and one of it's distant moons. It may be necessary to zoom in on my photo in order to see the moon it should be down and to the right of the planet a good distance in relation to the size of planet, I noticed that looking at Uranus in the photo helped bring the moon out just like stargazing in real-time.
If anyone can better distinguish what I might have done right or wrong here any help would be appreciated (also forgot to change format save for my images so I am stuck with .bmp and setting it as a download, sorry for any inconvenience.) - - - J47(JAY)
Hi I'm new here.
Briefly looking through this site, it would seem this site is geared towards discussion regarding instruments. So in advance, I apologize if this is not the appropriate forum/website for my question. And. If at all possible, might anyone link me to a website that might be better suited for me. I looked on youtube, and a few other websites and nothing concrete came up as to where the appropriate place to post might be or what it was I was observing regarding moon activity on this early morning of 11/28/2017. So here I am and once again I apologize if this is the wrong forum for my question.
I'll be brief. My knowledge of astronomy is very limited. Though I've always had a passion for astronomy.
My question. What exactly was I observing in regard to the moon's orbit/position/speed in which it changed?
Now, allow me to set the stage. It was roughly 12:30AM here in North East Texas on this day of 11/28/2017. On my way to the store I stopped to take a look at the night sky as I always do. The moon was roughly at a 50 degree angle above the southern tree line. Forgive my ignorance but this is the best way I can describe what I was observing. In less than one hour the moon had radically relocated to just above the western treeline. Once I got home the moon was obviously no longer visible from this viewing point.
I am very curious as to why the moons position changed so quickly. I've never seen this before.
Is this a common occurrence within the moon's cycles and or time of year?
I look forward to hearing your responses. To hopefully shed light on what is seemingly a strange phenomenon to me.
Thank you in advance!
About to buy my first real scope and mount. I'm wondering if I can put upon you good folks to ask for your recommendations for the items in the title that will match up with and compliment the equipment I'm about to buy.
Top of my list at this moment is the SW EQ6 Pro with either the Explorer 250PDS or 200PDS (depending on the all the other items that need to get to at least make it usable fairly usable to start with and how that affect the overall budget).
If I have to (for cost at this time), I will drop to a SW HEQ5 Pro with the 200PDS.
Fortunately, my girlfriend/partner loves the night sky but I know she will want to see 'results' in the EP straight away and will want to mainly look at our Solar system and the Moon (not that I don't) but she hates the cold and has limited patience for waiting to see anything deeper than those for now.
Myself, apart from the above of course, would like to go deeper but also include astrophotography once I have got myself up to a decent level of familiarity with the kit. I have a humble Pentax K20D DSLR and my very old Pentax Spotmatic F (Wet film) camera (It's been with me for a long time and still gets used once in a while).
I would very much appreciate your collective wisdom regarding the title items and fitting my DSLR (primarily) to either of the two OTA's above. What is the minimum I need to get, make/models that will get me going and that will complement each other and the system without having to take out a second mortgage just yet ;-) and get me off to a fairly good start.
I'm sure you have all had these questions before and I apologise if your first thought is "not again" :-) ... It's just that I have been lurking in the background of the site for a few weeks now reading up as much as I can and trying to pull a list together but my brain seems to have turned to fog now and after reading something earlier to day of EP's and Barlow's and that the optics in them (for want of a better word) should be in 'harmony with each other and the system, I've completely lost where I thought I was going and then also the subjects and threads that I had been using to 'guide' me elsewhere on SGL.
Many thanks in anticipation.
