There seem to be no trustable 3x barlows under $50.Ģx Barlows are easy, work well with short scopes and won't be expensive, so make your magnification calculations assuming you'll own a 2x.ĭespite Ed's sound advise on the mount's ability to hold the 150, I still agree with Penarin: I'd choose the 150 and accessorize later.Įdited by Adun, 01 March 2017 - 06:14 PM. They are mostly used by astrophotography guys to achieve focus on small sensors.ģx barlows can be good, but only the high quality ones (which can cost a lot). Not from experience, but what I have read is that 5x Barlows don't work for observational use. So, my recommendation would be for the Starseeker 130 Kit and a zoom eyepiece when you have an extra $60 to spare.Įdited by aeajr, 01 March 2017 - 05:58 PM. In fact I just ordered another one at a higher price point but I still enjoy the Celestron and recommend it often for those on a more limited budget. Not everyone likes Zoom eyepieces but I love mine. But many times I stay with the zoom even at this I sometimes use wide angle (60 and 82 degree) fixed FL eyepieces for very high magnification in the 8.8, 6.7 and 4.5 mm FL range. I use single length eyepieces for lowest power wide views, under 25 mm. Then you can add single FL eyepieces as you go along wherever you feel you need them.

If you later wanted to add a 3X barlow and pair it with the zoom you would have all magnifications from 27X to 243X, pretty much the full range of what your scope can handle. I think that is a terrific combination and that is what I use in all three of my scopes most of the time. If I then put it in the 2X barlow it would provide 54X to 163X and all magnifications in between. If I were to put that in your scope it would give me 27X to 81X and all magnifications in between. I have a Celestron 8-24 zoom ( $60) which is my most used eyepiece. Now, I have a very strong liking for Zoom eyepieces. A very good starting set of four magnifications to start. Your included 23 mm and 10 mm eyepieces give you 23 and 65X without the barlow. I would recommend the kit and work with the 2X barlow. For an extra 10 you get a moon filter, an AC adapter and a moon map. It includes the very popular 2X shorty barlow which sells for $40. The Starseeker kit is $50 more than the basic scope package. I would not go higher than 3X barlow for visual astronomy. 3X are often used for short focal length scopes. A barlow makes your eyepiece act like it is in a scope with a much longer focal length giving you higher magnification with the same eyepiece.ĢX barlows are commonly used for visual astronomy. So if we consider that let's look at how magnification is calculated.įocal length scope/focal length eyepiece = magnification. Some targets look best at 50X so it is not always about high magnification. WIth my 8" scope I find I do about 90% of my observing below 250X based on atmospheric conditions and often below 200X. If you try to push higher nothing will blow up it is just that you run out of light to magnify. So, for this scope, consider 260X as about the highest you can go.
The atmosphere will often limit you to less than that regardless of your aperture, but it is a good top end to work from. Some basic rules of thumb - The maximum practical magnification for most scopes is approximately 2X the aperture in mm when viewing bright objects like the moon and planets, perhaps double stars and such.

Thanks again! Finally about ready to order and get it fired up! I hate when life gets in the way of free time. While a 5x sounds appealing, will that just destroy my image quality? I am trying to find a good guide on the do's and don'ts of barlows but am still looking if anyone has a suggestion. When it comes to one of the two aforementioned scopes, where is the line drawn as far as optical quality and barlows? I see Orion has a couple choices, a 1.2, a 2, etc. I work in a different field in optics, and frequently deal with unrealistic expectations as far performance of magnified optics and accessories. My question here is with Barlows and what to realistically expect. Note that there is the 130 scope and mountĪnd there is the 130 kit which has accesories included at a savings. It will work, no question, but going one from the top, the 130, has the potential to be the more stable set-up and that is a big plus.Ĭonserving cash for accessories is likewise a good decision. Typically the largest one in the family is at the limit of what the mount can handle, in this case the 150. Companies like Orion will take a mount, like the Starseeker and put a variety of scopes on it to create a family. Might end up going with the 130 for cost, and grabbing some accessories.Ī tip on telescope packages. Ok I am about to pull the trigger on the Orion Starseeker IV, debating between the 130 and 150.
