Venus is so brilliant (the brightest thing in the sky after the sun/moon) you can't really mistake it (although most people I showed it to thought it was an aeroplane!). And it was putting on quite a show near the moon earlier this year. It sounds like it might have been this that you saw (although ...

Globular cluster M13 is a good sight and easy to find. I have seen it from my garden the past couple of nights - low(ish) north east at around 10pm in the Keystone asterism.

Hard to know what to recommend without knowing what sort of stargazing guides you have to hand.

Good luck.

Hi Sarah, welcome! I'll second what Spike says. I started with binoculars, but it didn't take long before I decided a telescope was what I was really after. But I had always had a passing interest in astronomy since childhood, so it didn't take much extra reading for the bug to bite. But scopes are ...

Hi Andy I have used http://www.metcheck.com/V40/UK/HOBBIES/astronomy.asp in the past. Seemed pretty accurate when I first started, but of late, as with the TV, it seems less and less so. Take right now as an example - it's telling me there's 29% cloud outside. Well, I've just been outside and I can'...

Thanks, Olly. You're right. I have found the Neximage focal reducer and it's about £24. I might consider one for that price.

Visually, it's certainly not a high priority - another one of those "nice to have if I had pots of money to fritter away" accessories.

Thanks,
Rachel

Focal reducers for SCT

Converse to my previous question, are there any thoughts about using a focal reducer for webcam imaging (such as this: http://www.telescopeplanet.co.uk/ViewProdDetails.asp?prod_code=PON07A000016 ), which turns an f10 into an f6.3? Short of buying another telescope (dream on... :wink: ), I can't get ...

Hi Steve This is my understanding: As FOV and exit pupil are both calculated from magnification, they will both be affected by the Barlow. FOV = Apparent FOV/magnification Exit pupil = Aperture in mm/magnification Therefore a 2x Barlow will double the magnification, halve the FOV and halve the exit ...

Yes, you must get "Turn Left at Orion". I bought a copy then ignored it for the first few times out with the scope and wondered why I couldn't find anything dimmer than a planet. Once I picked it up, I wondered why I hadn't done so before. It gives easy instructions on how to find stuff by...

Thanks for the thoughts. I think for now I will relegate further Barlows to the "nice to have" category. I will certainly experiment with changing the position of the webcam relative to the Barlow, though, and see what happens. I vaguely recall reading somewhere that using the star diagona...

Barlows for webcam imaging

Further to Spike's question about Barlows, what are the thoughts about doubling up Barlows for CCD webcam imaging? I am using a 2x Barlow at the moment, but can I double up with another 2x to get 4x? Presumably, imaging at higher magnification is subject to the same pitfalls as visual observing (ie....

Hi Spike A 2x Barlow was one of my first accessories and I bought it at the same time as the telescope instead of indulging in an extra eyepiece. They are well worth the money getting a decent one because you then need fewer eyepieces to cover a range of magnifications. You can plan later eyepiece a...

And yes, satellites are pretty common. I see them most nights when out, some with the unaided eye, some winging across the finderscope and the odd one in the main field of view.

Ah yes, I remember it well. Mine will be one year old on Saturday (how sad that I even remember the date). The thrill of going to collect it from the shop, the excitement of setting it up for the first time, those first few viewings... magic. :D I too spent many hours gazing at Saturn last year, oft...
