Yes we are light polluted, but there is still much to see.

I have a neighbor that is developing an interest in astronomy. He has viewed a couple times thru my 10" dob, and enjoyed some nice late summer and fall objects. He mentioned 300.00 and refractor in the same sentence, and my reaction was to discourage that line of thinking, save for maybe an ST80 on a light alt az mount. I also recommended the AWB one sky. He would have 100.00 left over for a couple eyepieces. I'm watching CL for him, possibly for a 130mm class reflector, as they come up sometimes. He is mid 70's and kind of cool to dobs; too bulky. Any other ideas?

edit; I do have a few eyepieces to get him going, so the budget is for the scope and mount only.

<strike>Maybe look at an Astro-Tech AT72ED.</strike>

Sorry just realized this is actually $300 for a telescope and a mount. A refractor setup in that price range is not going to be great. I would actually lean towards a 5 inch reflector in this price range. The Astronomy Without Borders One Sky telescope is a great 5" reflector with a good alt/az mount, good focuser, good eyepieces. Only $200. Leaves room for a bahtinov mask to focus and maybe even a tripod to mount it on to make it easier. Another good one to look at is the Zhumell Z130 at $180, also a 5" reflector with a good alt/az mount, good focuser, eyepieces, etc.

Another approach is the Orion Short Tube 80mm (ST80) and just add a tripod like a basic alt-az mount. Leaves room for one or two good eyepieces.

Very best,

Abdullahi Archer

Your notion of showing him the views in a 10" and an ST80 is a smart one.

If he's liking what he sees through your scope, there's no way that he's going to be satisfied with a Short Tube 80's views!

You'd really need a 4" or bigger... Maybe you all can borrow one to see how he likes it. Definitely avoid anything on an equatorial mount; far too many novices get frustrated with them-- and with good reason!

Good input so far, thankyou. I know that a dob is the best bang for the buck, but really don't think that is an option. I'll have him look thru my 10" some more, and set up the ST80 at the same time to show the difference. The explore scientific looks interesting, something new. Long focal length Acromat. I read some good reviews about that Celestron fairly recently too; wasn't that on a heavily discounted sale price some months ago?
The question is why he wants a refractor?
<ul class="bbc">size
weight
cost
knows something about refractors
his mother had a refractor
You said he feels they dobs arebig and bulky but naturally that is his impression of yours. There are smaller and lighter ones but still they are bigger, heavier andmore bulky than a refractor on a tripod.

What is the point of comparing an 80mm refractor to a 250 mm reflector? Comparing your 10" Dob to an 80mm refractor seems like a very rigged comparison and really doesn't tellhim anything.There are 4"/102 mmrefractors in his price range. And a 102 is going to gather 60% more light than an 80. In addition the 102s shown are also 50% longer FL.They should be able to handle 200X under good conditions. Many would say that a 4" refractor is more akin to a 6" reflector. I don't know that there is a formula for the comparison, it is just what I pick up from the chatter on the forum.

I would say a 4 inch refractor on an AltAz mount with slow motion controls would be a great recommendation for a first telescope for a 70 year old with a $300 budget.All up around 14pounds. I don't know why you would resist it. Small, fairly light, pops in the car, no collimation concerns. Seems perfect. A 6" dob would be about 35 pounds.Perhaps he sees that you have the big Dob that he can share with you so he wants a smaller grab and go to team with your big scope.

Based on budget, with no other requirements given,these are the scopes I generally discuss. I have bolded the onesI would probably point him to as being the best fits for him based on budget alone and the fact that he observes with you in your big scope.

I also listed scopes up to $400 should he be willing to go over a bit. There I point to a GoTo refractor.Up to $200

If he can't move a dob around, he's not going to be able to move an EQ4 around, that's what those 102 Fracs come with. The alt az will have to do.

All of the scopes I listed areAltAz. None are on EQ mounts. The 102 refractors are all under 18 pounds all up.

I generally don't recommend EQ mounts to newbies and would never recommend one as a shared loaner scope for people who are not astronomy enthusiasts.

Yep, the ones you listed would be nice for him. The ones I were referring to were posted earlier, sorry for any confusion.

Well, the point of showing the 10" dob and the st80 togetheris to show how wildly different the views are, and that telescopes are not created equal. I also have several other scopes he can look thru as well; a 100ed, 6" f/5 reflector, and an 8" sct. Pretty good representation of scope types. Might be able to sway him from refractors; we'll see. Just trying to help someone enter the field in a good way. Great suggestions so far.

A search turned up that Celestron 102 az selling for 168.00- 172.00 for a few days in September....hope some folks took advantage of that.

I got this one when it was around $180. It has dropped down below $200 twice in the last 6 months, at least on Amazon, so perhaps it would be worthwhile waiting a bit to see if it will drop again before buying? I have no idea why it has been fluctuating so hard to predict.

"his mother had a refractor"

I would think, rather, that either his father or an uncle had one perhaps, if at all; or, perhaps he had one in the past.

In so far as an equatorial for beginners, this beginner had one back in the early '90s, and has one still. I'm still observing. Just because someone is a beginner, that doesn't mean that they're unable to understand how something works.

Unfortunately, the astronomy gods do not see fit to provide most entry-level telescopes with alt-azimuth mounts. I suppose they have a lot of extra parts laying around for equatorials.

A fast achromat isn't very good for brighter and bright objects. I have an 80mm f/6 achromat, so I strongly suspect that an 80mm f/5 is going to be even worse, neither being at all versatile in observing the gamut.

Well, lookie here: an 80mm f/8, and on an alt-azimuth...

I think that that one would be rather nice, for a beginner.

These new ES offerings look interesting and affordable. Wonder when they will be available....

In that the 102mm is ready for purchasing, soon enough I expect. The rest are ready for pre-ordering. What I'm wondering is when these will be be available, too...

...and as "First Light" kits.

If he's in his 70s I can see where he wouldn't want something bulky, and would prefer something simple. And it doesn't get any simpler than a refractor.
