Hello :-)
Great "little" telescope!
Whoever gifted it to you/your husband got something decent (compared to what often is sold in stores).
filters
Filters can slightly enhance the contrast on planets (but very slightly, also make things dimmer, and planet season's about over for now).
Light pollution filters have limited effect. IMHO getting some better eyepieces and getting to a darker location is the better way when starting out :-)

Do you have a good guide? E.g. "Turn left at Orion"? For finding deep-space objects it's crucial :-)
Also, binoculars go a long way, even cheaper ones like the Cometron 7x50 (Under $30 right now at Amazon. They show a much wider field of view, easier to find things in the beginning. More magnification is difficult to hold when searching faint DSO).
Usually I recommend a lot of eyepieces shipped from China, as it's a lot cheaper, so I'll focus on eyepieces shipped from the US :-)
You asked about a barlow in the other thread; These can work, obviously, but will reduce the contrast a bit. Especially cheap ones introduce chromatic aberration.
On a budget, there's nothing wrong with a simple achromatic barlow for around $20, but you get what you pay for :-)
A dedicated eyepiece will work better- but stay away from kits (overpriced, mediocre at best) and short simple eyepieces (e.g. Plössl-type are great but under 10mm they have poor eye-relief).
A 6mm 66° (-1-, -2-) so called "gold-line" (sold under various names) or 6mm 68° "red-line" would give you 150x, around the same magnification a 2x barlow would give you with your 10mm eyepiece. The "gold line" cost $17-$25 on Aliexpress or eBay via China, sometimes <$30 from Amazon.
A 4.5mm HR Planetary would cost $30 or so in China, a bit more on Amazon. 200x magnification. I would not go for more. If you search at Amazon for <eyepiece 58 4.5mm> you'll find several for $49 shipped from the US, or for $29 from China.
The 4mm (225x magnification) is more common, but while things to get larger, they already get quite dim in the XT4.5. More than 200x would benefit from a larger aperture telescope.
Avoid Plössl (52°) under around 10mm, avoid the fake Celestron 62° that are available cheap on eBay and Amazon. Avoid kits (2-3 good eyepieces go a longer way than a mediocre, overpriced set).
Clear skies! :-)
Hi :-)
They occasionally appear on eBay and Amazon, but a lot of stuff is sold out at the moment.
Check https://www.amazon.com/dp/B07H8YZHFT/ref=twister_B07MVSSW4V - it has been in and out of stock in the past months rather randomly.
Otherwise, the red line are supposedly the same; https://www.ebay.com/itm/SVBONY-Relief-Eyepiece-1-25-68-Ultra-Wide-Angle-6mm-FMC-For-Astro-Telescope/303352485310?hash=item46a13795be:g:x7EAAOSw8~5elnDh - but I do not have experience with them.
There's also a set of two gold-lines: https://www.ebay.com/itm/SVBONY-1-25-66-6mm-9mm-Ultra-Wide-Eyepiece-Set-Multi-Coated-for-Telescope/123800922578?hash=item1cd31c29d2:g:QboAAOSwpeFemPqy
And another place to check (out of stock atm): https://agenaastro.com/agena-6mm-enhanced-wide-angle-ewa-eyepiece.html
Else -> China -> https://aliexpress.com/item/32727027422.html
Aren't you looking to buy a z130? Then you should consider the 4mm 58° instead for planets. The 6mm doesn't quite cut it. I Have the 130p, and the 6mm 66° is nice for the moon. But for planets, you really need a bit more magnification. Avoid the 4mm 62° and short Plössl.
Astromania 4mm 58° cost $49 from Amazon, but only other ones in stock right now. Same for https://agenaastro.com/bst-1-25-uwa-planetary-eyepiece-4mm.html. The other listings at Amazon seem to be Marketplace listings from China, and they are much cheaper at https://www.aliexpress.com/item/32823985645.html.
Clear skies!
What's your budget?
On a smaller budget, the 6mm 66° or a 58° eyepiece. Usually Amazon has these for $29, but sold out often right now. Via China, $14-$17.
