Hey guys! Its been 8 months since i ve started the hobby of astronomy.I would like to dig deeper now,i am looking for a book in astrophysics that involves mostly formulas and mathematics.With so many books in the market its hard to defferentiate science books from just books with information about the subject
One of the reasons I wanted to buy a telescope was to observe the colourful double stars. Just read in July edition of Astronomy Now magazine that Albireo ,s wonderful colours will be washed out to some degree in a light polluted area.
it would seem pointless to buy a telescope for a light polluted back garden., If this is the case.
The latest edition of the Binocular Sky Newsletter is ready. As well as the usual overview of DSOs, variable and double stars, this month we have:
* Uranus and Neptune are back (just!)
* A couple of Mira variables near maximum
* Ceres is still available
* Review of the Bino Bandit
I hope it helps you to get the best out of these short summer nights with your binoculars or small telescopes.
To pick up your free copy, just head over to http://binocularsky.com and click on the Newsletter tab. You can also subscribe (also free) and have it emailed each month.

Last night was my first session in a good few weeks and my first light with my ES 30 lovely finder ep and great on andromeda and Pleiades.
Anyway onto the session I had a lovely selection of objects to go at including 2 double stars I’ve never observed double stars before so this was new for me.
I started of with this double star really easy to find and I have to say a beautiful object to observe.
The golden colour of the star to the left was very bright and the blue colour of the star to the right was very striking.
They were a lot closer then I thought they would be and gave me the illusion of moving closer together when I observed for a long period.
I used my ES 14mm which offered 107mag which was well up to the job.
Onto my second double, another easy to find object in the constellation of Cygnus.
I was surprised when I first observed it the gap between both stars is significantly bigger compared to Almach and the yellow star above the blue one didn’t appear as bright to me as Almach.
That’s not to say I didn’t enjoy observing it, the star field alone was lovely to sketch and to get the brightness and exact gap and orientation between both stars was a joy to do.
I decided to use my ES 9mm because of the pleasing view of the object and star field which gave me 167 mag.
Onto my final sketch of the night and honestly one of my favourite objects to observe.
The star field was simple stunning I struggled to fit it all in my ES 30mm which offered 50 mag.
I couldn’t make out and gas around the 7 main stars but the brightness was very intoxicating and I spent a good amount of time trying to get the stars in the right position.
In conclusion a very enjoyable night and a great start to the new season.
Clear skies ✨????
