Telescope bamboozlement!? Help! Beginner/travel

Hi all,

I have read many forums and articles and to be quite honest, am getting a little overwhelmed by it all so hoping you can help.

My boyfriend has a massive interest in stars, space and planets and would love a telescope. I thought I'd surprise him for his birthday.
We live in greater London, with a tiny garden but we have a lot of parks around us and we go camping/travelling a fair ...

Query about brightness ratio chromosphere and photosphere

Hi Everyone

I would be very grateful if someone could answer this question for me.

If you divide the brightness of the uneclipsed photosphere of the sun by the brightness of the chromosphere that can be seen around a totally eclipsed sun, what is the result? (Obviously when I use the word "chromosphere", this should not be confused with the corona.)

I am having difficulty finding the necessary information on the Internet in order to ...

Refractor best for photography

Hi,
First post so Hello.
I spent an evening with a local group of stargazers and found it interesting to say the least. So I would like to "have a go" myself.
I come from a photography background and although I would just like to gaze at the fascinating night sky, I can see I will get the itch to photograph it as well.
I am also lucky enough to have a garden a few ...

Images

Another simple question I am sure... I have taken many images from one night, with DSLR on the back of my scope. Having downloaded them onto my laptop they are no longer jpeg images so will not show up in the files when trying to upload to a processing prog such as MICE or registaks. Can anyone tell me how to alter them into a format where i can access them in the folder which ...

Making mosaic pictures

I am beginning to create some simple pictures of The moon with my Alt/az mount at the moment. As my camera is not full frame I would like to/believe it is possible to create mosaics to join the various sections together?

Can anyone help me with how to do this please?

Thank you

First telescope for digital photography

Hi

My wife has given me a budget of £500 (you know how it is) to get a scope for use with my Sony a7ii and to use with the kids.

I have zero idea but the celesteon nexstar 4 se has caught my eye. Is that completely wrong or any good or something else I should be looking at with the budget I have please?

I need to absorb the wealth of your knowledge ...

Changing/upgrading mounts

I have had a Celestron evolution 9.25" scope on an Alt /AS mount and am realising that with a f/10 ratio I am not best equipped to move into the world of Astrophotography. Without changing everything very expensively can anyone suggest what mount may be able to take the weight of my scope which is around 16kg.

Many thanks for any help you can give

Using Celectron Telescope

Hi,

Recently I have been presented with a "Celestron Astromaster 130 EQ Telescope. I also received one 10 mm and another 20 mm eye piece. Although I can see the stars through both lenses, I cannot see the big moon visible in the sky? What am I doing wrong? Is there are any set up or lenses needed to view the moon? I am a beginner and am frustrated as I could not see the ...

Finder scopes

My Celestron Evolution 9.25 came with a small red dot eye finder which has had some success bu i now feel it needs to be replaced with something a little more precise. Any direction or advice about what I might consider as an upgrade would be very much appreciated.

Thank you
