Insights Planning to buy a first telescope? - Comments

[russ_watters]

Why can't I see anything from my telescope ? The moon looks great but besides that I can't find anything ? It's really cheap think it was Around £200.

What else have you tried to find? Jupiter? It's pretty easy to spot right now and looks great even in a cheap telescope.

[edit] And FYI, there are two moons transiting in front of Jupiter tonight. You should be able to see the shadows with even a cheap telescope.

 

[Keiran OConnor]

Yeah Jupiter and tried finding Venus, I heard it was close to the moon all last week. Very cloudy up my end past week or so unfortunately :(.

How dark is your sky? I can see very little from where I live near NYC with my fairly powerful telescope, but if I bring it to my mother's up in the mountains, I can see much much more.

 

[Keiran OConnor]

Erm... Pretty dark, won't have the light pollution of somewhere like New York. I live in a town just off Liverpool (pretty rural area).

I bought a s/hand 200p Dobs recently and immediately got myself a couple of good eyepieces. Using such a crude mount makes you learn fast about finding things up there. 8" is very good for dim objects but it does require some effort to get it out into the garden. I haven't traveled with it yet but I plan to use it on the back of my truck, which would be more pleasant than scrabbling around on the ground in some random open field.
As people have already said, the best one to buy depends on individual circs. I think I made a good choice 'for me' and the views can be stunning.
Start cheap and you can always sell it on for a better chosen upgrade. (Sell before buying another. Be strong!)
Go-to is all very well but, like sat nav in cars, it doesn't give you a clue where you are or how you got there. It's something to aspire to when you have learned a bit about the business.

Enjoy the shaking of the entire truck as you shift around.

Yes, I did try it and it was noticeable. But the Hilux has very stiff suspension and it wasn't too bad when I wasn't dancing about. A couple of scissor jacks could solve that problem. All this stuff is about problem solving and feeling smart when it works!
At the moment, we have wall to wall cloud and rain stopped play in the UK. It should be so much better now that the Moon has gone on holiday on the sunny side of Earth but . . .

The other problem with being on a truck is that you won't be able to easily position yourself to block sources of light pollution.

I wondered about that. There are several local spots (including my garden) that are not bad for light pollution when I turn our own house lights off. But the extra height will take me above hedges and things. At the moment, Mars and Saturn are too low in the sky for me to see them from my garden (especially as the Dobs is so near the ground). I shall just have to experiment. It's the little practicalities that make hobbies fun. I just ended a long and involved relationship with a Sailing Cruiser and she was crammed full of practical problems to solve (never pay someone to do something that you can do yourself, of course).
Talking of light pollution, I have a feeling that I could benefit from a blackout sheet over my head like old photographers. I'm surprised that I haven't seen something like that on suppliers' sites.

I've done scoping from my backyard here in the big city. Planets are bright enough that it's not an issue. But if you're looking at anything else, you'll want your full night vision, which takes a half hour to kick in. And any light source is enough to destroy it, even a streetlight a mile away, or light from a neighbor's windows.

But the extra height will take me above hedges and things.

Frankly, I prefer an area where the horizon is high for two reasons.
1] It hides a lot of light pollution. If you're high up, any light within ten miles will destroy your experience.
2] The viewing near the horizon is dreadful anyway. Air disturbances, sky glow and the shear thickness of the atmo make it very poor viewing.

Talking of light pollution, I have a feeling that I could benefit from a blackout sheet over my head like old photographers. I'm surprised that I haven't seen something like that on suppliers' sites.

Your night vision takes more than a half hour to reach optimum, and less than one second to be destroyed. You'd need to wear a sheet over your head for the entire night.

but if mounted on the truck, then there his the huge advantage of being able to drive to a darked site :)

For some playing around at home and to keep the local light out of your eyes, it would take very little effort to make a frame to fit the
truck deck and secure a black material to the frame. If out of aluminium tubing, you could make it fold up and the material permanently
attached to the frame.Dave

 

[davenn]

wonder what happened to @Keiran OConnor ?

would be nice to know if he is now making use of his scope ?

you can do that whether or not the scope is mounted or simply stowed...

Yep, and now you got yourself an actual observatory.

AND - since the best viewing tends to be in very cold air, such as winter - you won't freeze your Plossls off.

Mobile observatory sounds cool! I was wondering about a suitable design for a helmet, too! I wouldn't mind betting that some Victorian geezer has got a patent on something like that.

 

[jim hardy]

There are plenty of compact film cameras about in the junkshops. I've been known to disassemble one and mount its lens in a plastic pipe fitting for an eyepiece, in a pinch.
Want to try one of those with zoom ...

Saturn is spectacular now.

 

[davenn]

Saturn is spectacular now.

yup, it's at its best for the year at the moment

 

[sophiecentaur]

In the UK. Saturn is a bit too low on the horizon and is too much on the fuzzy side*. I may have too high expectation, I suppose. The rings are very visible (as a single one on X150) and I was v. chuffed to see it, first time. Jupiter, being much higher, is much more stunning from here.
My commercially minded 'man at the shop' tells me I need to launch into astrophotography if I want better pictures. But that is a potential money pit.
*Much better in the southern hemisphere, I guess.

 

[Thomas McGuigan]

Wow! Thanks for the great post. I only recently started thinking about astronomy. Binoculars are great, but I have trouble keeping my arms steady enough to get a good look at anything. Any good ways to keep binoculars steady?[/QUOTE
Me too. I need to find a good telescope.

 

[sophiecentaur]

A good tripod is probably the best incremental value if you have a good pair of binos. Nearly all of them have a fixing hole for a cheap adaptor.
Choice of telescope depends on your money, your strength, transport situation and suitability if your garden.
Don't even consider the rubbish that's on sale in non-specialist stores. Ugh- nasty.
Read a lot of different opinions before choosing. Your personal formula is very important.
I thought a lot before my choice and no regrets (for me). I got an 8" Newtonian (Dobson mount) which will (they tell me) allow me to see loads of stuff. Still waiting for right conditions and my learning process.

 

[sophiecentaur]

if you have a good pair of binos

Canon make a range of extremely sexy image stabilised binoculars. Big / small and high/ low magnification. The only trouble is that they will set you back nearly 1kGBP which could buy you a fairly respectable s/h telescope and mount. But bins are good for much more than stargazing. More decisions. . . . . .

 

[logan merriman]

my first telescope was a celestron equatorial 114 powerseeker id go with that its around 130 i think

 

[DennisN]

I've been thinking about getting a telescope for years, and I have finally done so!
I decided to go for a very cheap entry level scope, since I wanted to get a feel for the craft before I go for better stuff (which I very well may do).

I am a little embarrassed to share the specifications here since it's probably a comparatively shoddy piece of equipment, but anyway:

It's a 70 mm refracting telescope with a focal length of 300 mm, and it came with two eyepieces, one Barlow lens, one erecting eyepiece, moon filter and a mount. I paid merely $35 for it (link to the telescope is here).

First impression: I actually managed to assemble it without the instructions. I looked at the Moon the other night and was very pleased with what I saw; for the first time I clearly saw with my own eyes surface details, craters etc. It was quite a moment for me, I have to say.
Magnification with the various accessories is from 15x up to 150x. Later I will try to fit a camera to it.

The mount is not very good, and neither is the stability, but what can I expect for $35?
A small cost for a man, a giant leap for my eyes! Maybe I will post Moon photos on PF later...

 

[sophiecentaur]

I clearly saw with my own eyes surface details, craters etc.

A brilliant experience! Take a look at Jupiter, too. It's pretty visible at this time of year. Those moons will blow your socks off although you may not see any detail of Jupiter's actual surface. Impress your friends too!
Unfortunately for you , it's the beginning of a slippery slope and you will need to be strong to avoid limiting your spending to a sensible level. Food and new shoes for you (and the kids?) are actually a priority.

Thanks, will do!

Impress your friends too!

I will definitely do that!

awesome, Dennis

As Sophie said, it's the beginning of a long and slippery slope as aperture fever sets in and the bank account starts to feel the strain

a solid mount ius very important and if you find the optics are not too bad, then it may be worthwhile investing in a better mount
to stabilise the unit in a better way

If you haven't already, don't forget to download Stellarium
http://www.stellarium.org/

and then start to learn to star hop around the sky to find objects

[DennisN]

Thanks, Dave!

Yes, I've heard that telescopes and astrophotography can be quite addictive... a fun thing is that I've got a shopping list of accessories to get (e.g. better eyepieces, barlows, various filters, camera adapter, finderscope) and the cost of the accessories I plan to buy are about 3 times the cost of the telescope I bought... but the accessories will be useful for a possible future new telescope, so I don't mind.

Thanks, I will definitely consider that. I realized the importance of a good mount very, very quickly with my shoddy mount The last time I checked the Moon with my bare eyes it did not bounce up and down or back and forth... If I upgrade in the future I plan to get a scope with a motorized mount, since I'd very much like to be able to take long exposure photos.

Done .

Just make sure the mount you get is a good one. Wait the extra month or three if you need to save up more. Trust me, it's worth it. You do not want a so-so mount when doing astrophotography...

Same goes for the rest of the gear too I suppose. I bought some used equipment and have been plagued with equipment problems ever since.

But I should add that I am aware of the photostacking option too, of course, as the youtuber Forrest Tanaka describes in this video from beginning to end:

Astrophotography without a star tracker


He had a tutorial also on telescope guiding. I've watched all his tutorials, I post them here for others who may be interested:
