I don't really know what type of barlow is this, but I like to use it specially for terrestrial observation and the image quality is good (I have a 20mm erect-image eyepiece and with the barlow it makes a 10mm). For observing the sky, it does get objects at the edges a little bit out of focus but overall I think the quality is good.It's not the best barlow you can get but it's definitely a good first barlow lense, and the price is excellent!!

I wasn't impressed with the quality, regardless of what category it falls into. I rarely if ever use this lens.

If you are referring to the tuning knob, mine is still good. Sorry thatI could not help!

I understand that if the "part No." has 23BY at the end (e.g. FX888D-23BY) it is blue & yellow. Otherwise there is nothing at the end and it is silver/grey..... check the "part no." instead of just the "model no."

Hi, a barlow 3x is a very good acquisition. For both stunning moon's surface details or planetary observations (Saturn will pop up at the size of your pupil, what means great observation of rings). You have a 1,000mm focal length telescope. With a 10mm eyepiece, that means 100x power. With a barlow 3x, that means 300x power. Without a motorized mounting, that is the limit for observation (motion due to earth rotation is too fast with such reduced field of view). A barlow 2x will give you very good views of Saturn with more comfortable observation (more time to focus and keep eyes on). On my refractor, which is not neither APO nor ED, barlow 5x gives no resolution, due to chromatic aberration and other effects. So, barlow 5x, which, in your case, means 500x, may be not so good, due to same reason. The image is quite large but both impossible to keep on view field (due to rotation) and nothing more clear than a blurred image, due to lack of resolution in my telescope. I hope this helps.

I used a 6mm with a 2x Barlow and I was very pleased. My old eyes could only make out much ring detail but my girlfriend (20/20) was telling me she could make out very fine detail.

I don't see any authentic PX100 [original/classic] anywhere on the web or fleabay now. If anyone knows of authentic, let me know. and for you who use them, know them, know the competition - what's the alternative?I use mine for live sound - i'm a bassist and occasional guitarist - these work so stinking well with my personal mixer.... incredibly clean, do not color, efficient yet will not clip unless stupidity sets in.

The color changes easily. The rx2 and rx2n are very different gauges. I suggest going to the webpage.

I had both the black one and the silver one....both are the same. Depends on what color you want. The silver one is the first edition...so you might be able to get a better deal. I liked the black one because it matched every thing I had better. Both operates exactly the same. Be aware you will need to adjust the pedal switch to operate correctly on either one. See YouTube

I would return the pedal it is defective. The one that I purchased for a museum class I taught ...so for is working well... though my personal dremel pedal is of much better quality than this particular product.

I had an ivory colored one a long time ago, and to me, the tone and feel is pretty similar. This one feels perhaps a bit cheaper, but I was really impressed at the quality of this, having expected it to to feel and sound very cheap. Hope that helps!

I use the color checker for everything from macro ring lights. Studio lighting, etc and combinations of any two sources. There's no way of knowing accurate colors otherwise. I see huge differences - to me.

Its ok i guess. I have the power acoustik rz4 2000d's. Ran 2 of them to 2 of them 15's. Have them for sale now for 150$. Less fuses the better. That one has 2

I would say it's more black than grey, like a gunmetal grey. It looks absolutely stunning, in my opinion.

It is "abby normal"! Check to see if the battery is still good and also check to see if it has leaked and corroded the contacts. If the battery contacts ARE corroded they can be cleaned with sand paper until they shine bright. Install a good battery and check for normal operation. Electronic gear can die at any time or live forever, no telling. Good luck!

Yes, a good one. I,m using the UMC 200 and it is excellent. The difference between a fine one and a common one is like day and nigth. I was very surprised.

I've never been able to get an answer. I've been told that it is "tinned pure copper." I did end up using it and haven't had any issues. I ran a dmm on it and got a 14.11 idle (with the ac on) and it only dropped to 13.96 with hard bass hits. It definitely is 4 gage though.
