SkySafari on iPhone or Android is very good for doubles.
I have downloaded SkySafari for my iPhone, it seems wonderful, I love the rendering of the night sky and star colors, having a look at the menu options in settings I can't seem to find a function for pointing out doubles. It is a wonderful looking app, regardless, i'm sure i'll figure out how to identify doubles through it.

Wonderful images!

The legendary Telrad has always held a special place in my amateur heart but, with my new refractor the space wasn’t available. After having a look at it I tried removing the telrad from its base, i noticed that the feet fit almost perfectly within a millimeter between the cradles. Problem solved, just a small strip of double sided tape, enough so I can easily pull it off for transport makes for a fine and strong fit. Whenever I need to remove it I can pull it off and apply just a 3/4 inch piece on either end in seconds. Looking from the eyepiece, the distance means I cannot see the outermost target ring but, I have never needed it anyway.

Cambridge Double Star Atlas
Is this in software form?

Lately i have taken quite a liking to observing doubles but, having never really paid much attention to them previously, i find myself searching them out anew. Looking through Stellarium menus, i could not find a
selector for identifying doubles. Can anyone recommend a way i could use stellarium or other means to find doubles in the spring/summer northern hemisphere?.

Yes, my scope is no longer new, maybe a year or so but, when I remove the dust cap I can smell that same solvent type smell.

This may be useful for you.

Welcome! from near you in Stouffville, i too am mainly a visual guy who occasionally snaps images of planets with a cheapie camera, enjoy your stay at SGL.

One could count the photons those two little guys take in, sounds like a load of fun, clash of the anti titans.

Welcome! Here too I had a mimi panic attack when I noticed that solar filter eyepiece, was afraid you’d have a go at it and risk your eyeball. As mentioned above, put that straight into the garbage bin, they can shatter with the intense heat and cook your eye.

Welcome!
Thought I would add, regarding scopes for specific purposes, a scope gathers light and magnifies it. Some objects are much fainter than others, like nebulae are harder to see and fainter than planets or the moon. For faint object we like large aperture telescopes like dobsonians for example, these gather more light than let’s say a much smaller refractor and, allow for one to see more of any particular nebula or faint galaxy. That being said, those large scopes are also great for planets as well, whereas the small scopes won’t provide as detailed an image as the large ones on faint objects. In short, small or large, one can see faint objects better in large scopes than small ones.
Most of us experienced amateurs have started out with one scope but, over the years have yearned for larger scopes for those galaxies and nebula. Eventually you too will find you’ll have more than one for different objects. In the meantime, select your first and enjoy the heck out of it. Learn your way around the sky, you will find you may like viewing a particular type of object over others, then is when you’ll find you want a better suited scope for your needs.

Perfect. Let them wait in Stockholm 😉😄.
A nice example of pareidolia, I love it! Did you see it visually or only afterwards on your picture?
It caught my eye fairly quickly one I had put in my 9mm eyepiece, from then on it became so evident that it distracted me from the rest of the surface, lol.

Yours kind of looks like an Orc from LOTR, now my question is, will I see this face again anytime this crater is visible? will it only be visible exactly as is in my original image when factors such as position of moon/earth relative to sun are exactly the same again?.

Also, what scope type.. newtonian/refractor were you using, so I know which way up you were looking! Looks like you’re not in the UK, so *roughly* where you are would help, though I think I’m narrowing in on a likely location. L-R inverted image.....

Hello, that night I was just using my phone to capture random images, I thought I would mention that to explain the bad quality. Having said that, the images were shot this past Friday at 10:05pm from Stouffvile Ontario, Canada which is just outside of Toronto Canada. The scope used is an Orion Eon 115mm triplet 805mm focal length. For those shots I was almost certainly using my 9mm Morpheus combined with the TeleVue 2.5x powermate but, I may have used the zoom feature on my phone to bring the artifact in a bit closer.

Pareidolia?🤔
Not sure what that is.

Hi Sunshine,
I know this is an old old topic but i was fascinated by the documentary, extremely interesting for an archaeoastronomer, so had to thank you for posting it!
I only go back to the start of the Julian Calendar on 1st January 0045 BC, before that is difficult, i'm not sure that the Moon's orbit is true to ages, which can effect spin of the Earth.....i'm out in no man's land if i go back to 28th May 0585 BC, at 18:32 PM with an adjusted Julian Calendar, what i'm doing now is dubious, i'm aware of Delta T, so take the picture below, being 28th May 0585 BC as dubious!!!.
Weather is not reported, I cant know how dark is was behind a storm cloud with a partial Eclipse, and what we don't know regarding the spin of the Earth, but is fascinating how it stopped a battle over two and a half thousand years ago regarding an eclipse, however regarding the orbit of the Moon effecting the spin of the Earth not being constant is a factor to location.
It is still a fascinating subject, i can't be sure of location but i have done my best, regarding information over 2,500 years old!

Astronomy picture below.Thanks for the links, very informative and, i must admit, archaeoastronomer sounds so fascinating. I'm glad you found the documentary fascinating, NOVA is my most beloved series as i have been watching episodes since
i was a child. This one about the Antikythera Mechanism was one of my all time fav episodes. The dvd is available on Amazon, i have it, many other NOVA episodes also are on DVD.

i paid for it, going to have a go at those settings you show.
