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)
Can anyone confirm (or refute) - have I imaged Ganymede and Europa in orbit around Jupiter or is that just wishful thinking? (Only equipment used was a Lumix G7 with 150mm zoom lens - effectively 300mm with 2x crop factor - and of course a tripod).
It appears to be the case and yet I can't quite allow myself to believe it...
Thanks from an old newbie.
Just thought I would say hi to everyone.
I am a Noob, but have been googling astronomy for past year, so am familiar with some of the lighter terminology.
Most of my googles have directed me to this site, so I have already read forum posts here numerous times.
Have already acquired quite a bit of kit, but just not found the time to try it out yet.
This should hopefully change soon as I am expecting to have a lot more spare time in a couple of months.
Being in the Midlands in the UK, I am not currently missing much, due to the current cloudy weather here.
I am looking forward to picking your brains and in time posting some of my experiences here.
I have just joined and have been looking around, and putting in various searches to find the answer to my question(s).
I have already found some valuable information, but i can't find a specific answer to a question i have relating to exposure times.
I have shot the milky way several times before, from a tripod and a wide angle lens. I am aware of and understand the "500 rule" and that worked fine for me at first when i was shooting with my Canon 6D Mark II. When i moved over to the Sony A7III i noticed significant trailing using the same rule and that led me to the NPF rule (Via the photopills app incase people dot know).
I am heading back to Tenerife once again in about 6 weeks time and want to buy a star tracker so i can get some really detailed images.
I have done a fair bit of research and in principle, the whole thing doesn't seem to be too daunting or difficult.
I have purchased the Polar Scope Align Pro app so i can align Polaris as accurately as possible, i will practise putting the unit together and familiarising myself with the different parts etc, but it is the exposure times that i do not understand.
My best glass is the Carl Ziess 50mm F/1.4 Planar, the 18mm F/2.8 Batis, the Sigma 35mm F/1.4 Art & the IRIX 15mm F/2.4 Blackstone.
I currently do not own, nor have i ever used a tracker, and I cannot find any information relating to which aperture, ISO and Shutter length any of these focal lengths should or could be shot at.
Is there anything similar to the 500 rule or NPF rule that relates to using a tracker with varied focal lengths? or is it just a case of stepping the lens down for sharpness and then trial and error?
Thanks in advance,
I'm a complete beginner and have a similar question. I'm thinking of buying a Celestron astro fi 130mm newtonian telescope what would I expect to see and what clarity? https://www.celestron.com/products/astro-fi-130mm-newtonian-telescope
Can't wait to get a telescope and explore the skies.
