Back to Basics?


FLO

Recommended Posts

I have been comparing November 2011 telescope sales with November 2012 and have noticed a strong trend away from the sophisticated GOTO models like the Celestron 127 SLT and Celestron 4SE towards more traditional models like the Skywatcher Skyliner 200p and Explorer 200p EQ5. That is only one month and one retailer but the shift is strong so I am guessing others will be noticing a similar pattern.

I am not sure why we are experiencing this trend but it might be a good thing because it means people are learning to star hop and observe at a more relaxed pace. And what isn't being spent on GOTO is being spent on aperture. The light gathering ability of an 8-inch telescope is around 150% greater than a 5-inch.

Very understandable, at that aperture, it's better to be able to spend money to be able to see a certain object rarger than just having it in the field invisible because GoTo can find it, but you can't see it because your scope doesn't have the light gathering power needed.

I think the effect may be regional, or at least possibly split between dark areas where you stand a hope of manually finding objects, and cities where it's more difficult - I'd love to see the stats.

As for money, that may be regioanl too.

Thats rather interesting, i wonder if it has anything to do with more social groups meeting up... a good star hop is always the highlight of a group obs session for me, always generates good conversations around them too

I would consider 150% greater as only being a 1.5 times increase.

50% of 10 is 5, 100% of 10 is 10, a 150% of 10 is 15

Not to harp

Its 20 to 50 sq inches

100% of 20 is 20 that will give you 40sq inches

50% of 20 is 10 that will give you 50sq inches

total 150%

Might it be something to do with the very effective Pro-Dob lobby here in the lounge. Absolutely no criticism BTW, but anyone doing there first scope research on google.co.uk stands a very good chance of picking up reviews and general advice herein.

Hopefully the end result is that more people get decent first scopes and go on to develop the interest, rather than getting disappointed with inferior equipment, frustrated and turned off by the whole experience.

It's purely a semantic thing. You're talking about an increase of 150% whereas Kev is talking about an increase to 150%.

It's the language that causes the problem. The maths is clear. There is absolutely no doubt that 150% of 20 is 30 and that 250% of 20 is 50. Any mathematician will tell you that. Anyone can argue otherwise until they're blue in the face, but they'll still be wrong :)

I see your logic and feel a tad daft now

Not all retailers are pushing the 'back to basics' approach. A friend at work asked for some advice before committing to a scope purchase. I didn't even know he was interested! He had phoned a retailer advertising in AN and they recommended one of the 130mm Goto options for £369. I quickly put him straight and that lunch break he ordered the 200P dob. Sadly not from FLO, i did recommend and he did try but couldn't get a response on the phone. So RVO got the sale as he was impatient. But importantly another budding astro buddy swayed away from a tiny scope with a ridiculous sized Goto library towards a basic scope with aperture to last a lifetime.

I agree with James, there isn't the money around to spare.

One of my mounts is still manual the upgrade will be to dual motors not goto.

Equally I read too many problems with the Skywatcher goto systems to want to add one of theirs to the mount at this time.

The beauty of pop in an eyepiece focus and pan around is by far the best thing the manual dob provides, the natural ease of this just makes it a pleasure to use.... must get one again at some point.

Just to be clear we aren't pushing one approach over another, we only noticed a trend. We have our preferences but we try to be neutral. The Celestron 127 SLT is an excellent telescope for back-garden astronomy. Many astronomers live under significant light pollution so achieve best results observing lunar, planets, solar (only with a suitable filter!) and brighter deep sky objects like globular clusters, the Ring, Dumbell, etc. And the 127's high magnification, high contrast Maksutov optics are perfect for those targets.

We haven't noticed a bias here at SGL towards Dobsonians but if members are advising beginners looking for a good budget telescope to buy a Dobsonian, then that is good advice. No other telescope design offers as much aperture for the money. Aperture isn't everything but it certainly beats whatever comes second.

We all have preferences and there is no harm in voicing them if they are neutral and well meaning :angel:
