I'm selling these 2 filters since I'm getting a mono astro cam. The filters are barely used and in perfect condition, no scratches, no fingerprints, not even dust. They are both amazing filters, probably the best investment I've made. I've attached some images
taken with these filters, using a 100$ celestron newtonian, a 250$ Canon 500D and the infamous AVX. Also attached are images of the filters showing their perfect condition.

First the disclaimer. This is my first attempt to sketch Mars, or indeed any planet. Also, it started to rain and I had to abandon it with some urgency (hence no orientation marker). I used a HB pencil and a blending stump. But I think I can see a couple of features that match Ade Ashford's app.
The Wratten 21 filter improved the view enormously (although you may find that hard to believe looking at the picture) helping show the surface detail and improving the seeing. I tried it the day before in my 80mm refractor, but that just made the image too dim, but on the 115mm it was very good, so I recommend it to anyone with 115mm or larger.
I tried sketching the moon (Plato) several years ago, but SWMBO pronounced it (I'll paraphrase her here) more Feline Anatomical than Selenographical. While this one may look more like a two year's old attempt at drawing a rabbit, at least no one can confuse it with the rear end of the cat. So regardless of the criticism I receive here, I'll give it another go tonight (weather permitting). 🧐
I am thinking about buying a Celestron Nexstar 6se to use for astrophotography at a very beginner level. I am thinking about using a ZWO ASI224MC as it seems a good option. I have a few questions about how to setup/use it - here they are:
1.) Do you just screw it on where the eyepiece is usually at?
2.) Do you just have the cable going to a computer where you have stacking spect where that stacks the photos it takes?
3.) Does it automatically take photos of planets and DSO’s?
4.) Does it need any filters to get color on nebulae as those are they primary things I want to photograph
Thats all, as you can see I am a beginner to astrophotography and just want to know how to use the camera to take decent pictures.

Hello all. Thank you for taking a moment to read this & offer your suggestions/ advice. I'm sure my basic question has been asked many times: "In your opinion or experience, what are the first, most important, necessary accessories I should add in order to maximize the the use and ease of a newly acquired Celestron Nexstar 127 SLT ? I have a power supply adapter, 9mm,10mm, 25mm eyepieces, 2x Barlow and 90 degree diagonal mirror adaptor. With a modest budget and a 2 week deadline, I've researched numerous reviews and narrowed some choices to additional Plossl eyepieces, an assortment of filters or a dew shield. All of and these can probably be purchased within my budget but I'm even willing to take the plunge on an upgrade to a better mount, which I have no idea where to start. Any and all suggestions, advice and opinions are gladly appreciated. Thank you all, from across the pond in northeastern US.
I have been waiting for this telescope for almost five months. Since May, 19th, to be precise. The day I went to the TS Italia store and saw for the first time the SLD model, model now discontinued. I even missed the last available piece just for a few days, once I finally placed my order, June, 25th. It was to be replaced by a newer model, available at the end of the Summer.
Boy, am I glad I did miss it. The wait was definitely worth it. The new and improved model is simply beautiful. I fell in love with it as soon as I saw it on the Tecnosky website a few weeks ago, when they posted the product sheet. But in person, it's even more beautiful.
So, the people from the store emailed me Friday, October the 2nd, telling me that it was finally available for pickup. I read the message only a whole hour later and it was soon going to be closing time. I started calling at 4:30 PM and I finally managed to get my phone call through at around 5:05 PM. The store closes at 6:00 PM and doesn't reopen until Monday. And it's 40 minutes away from where I live. I made it there in 35. There was no way I was going to have to wait till Monday, knowing my scope was only a few minutes away.
So, here's the pre-unboxing picture:
- top left, brown box, behind: Vixen clamp for guide-scope
- top right, white box: 60mm f/4 guide-scope
- top left, white boxes: T2 Nikon ring, 30mm spacer, adjustable spacer
- center, behind white boxes: Optolong L-Pro 2" filter
- right of filter: spacers mounted and already calibrated for 55mm backfocus, for eventual use of the ZWO ASI 224MC camera with the refractor
- top right, Bahtinov mask
- underneath the white boxes, top left: Losmandy bar to attach telescope to my NEQ6 Losmandy saddle
- big box underneath all of the above: Tecnosky 80mm f/6 FPL-53 OWL Triplet, with carrying case and 0.8x 4 elements flattener/reducer
- ZWO black case: ZWO ASI 224MC guide-camera / planetary camera
- front left: Talisker 57° North and two glasses (don't mind the shape of the glasses, they are the closest to Whisky suitable glasses that I currently own...) ready for me and my wife to celebrate the end of the wait
- front right: box for the aforementioned Whisky
I actually waited for yesterday (Saturday, the 3rd) for the unboxing, because I wanted my best friend Omar to be present and help me with filming and taking pictures. We have been friends since we went to kindergarten and we always have had astronomy as a common interest.
It just so happens, to my immense surprise, that my telescope is actually SN. 0001, so I own the first telescope ever produced of this new series. The certificate is also very promising, with a Strehl ratio of 0.974 and a Ronchi test that seems very well behaved. I like a little less the red edges on the lenses, but I guess only time and a proper visual - and astrophotographic - session will be able to tell.
Obviously the "new equipment curse" didn't help, but we got almost a whole hour with clear sky patches and obviously I couldn't pass up the opportunity. I quickly setup with the bare minimum necessities for a visual observation and me, my wife and my best friend Omar - who helped with the staging, recording and directing of the unboxing event - took a quick look at the Moon, Saturn, Mars, M31 and Perseus Double Cluster.
I can definitely understand now, even if the seeing wasn't perfect, and my eyepieces didn't offer enough magnification (25mm and 10mm give me 80x and 200x, with my C8, but with a native focal length of 480mm, even with a Barlow 2x, we could only achieve about 38x and 96x, respectively), what people mean when they say that an apochromatic refractor brings out the objects from the background sky. The contrast was stunning, the stars were absolute points, pinpoint, small and sharp (with my C8 they always have kind of a "blob" feeling), the contrast on the Moon was fantastic and I could see many details, despite it being almost full, and only at 48-96x. I think it passed the visual test with honors. I was also very happy to be able to see the Double Cluster all in the same field of view for the first time. Saturn was well defined, could clearly make out the rings - don't recall, in all the excitement, rush and cycling between me, my wife and my friend, if I saw the Cassini division, but I'll definitely try again next clear sky night. Mars was also beautiful, could clearly see its rusty red color, the polar cap and some darker, black features on the surface.
I really can say it's a beautiful telescope, very well made and machined. The attention to details is really of another level, the paint finish is very nice and matte. Also very lovely all the different red and black anodized surfaces, they really give it a nice finish and personality. The focuser is also the best I have ever had on a telescope. Very smooth, precise, with no backlash. Coming from a C8 where every touch of the focuser throws off the image all over the place and the backlash is quite significant, I really appreciated how easy it was to fine tune focusing with a proper focuser, especially with the 10:1 focusing knob.
I can't wait to be able to take the first pictures of some star field, to check if even photographically the telescope lives up to my expectations. I hope to get pinpoint stars corner to corner and that the backfocus won't be something too hard to make perfect.
Here's some accessories.
Optolong L-Pro 2" filter, Bahtinov mask, Losmandy dovetail to replace the Vixen one the telescope comes with, Nikon T2 ring and spacers to use the ASI 224MC with the correct backfocus directly on the telescope, instead of a guide-camera.
Here's the 60mm f/4 guide-scome, with Vixen clamp.
And the ZWO ASI 224MC guide-camera.
Here's the mandatory celebration beer, at Corte dell'Orso (the Bear's Courtyard).
It's a Belgian sour beer, lambic style. Oudbeitje by Hanssens Artisanaal, with added strawberries. A very nice beer, sour, tart and fruity. Could definitely taste the strawberries.
Here's a couple of pictures of the full setup, with everything mounted on my Sky-Watcher NEQ6 Pro.
The setup is in its astrophotographic configuration: mount, telescope, guide-scope, guide-camera, filter, flattener/reducer and at the end the Nikon D5300 astromodified. All controlled by Astroberry on my Raspberry Pi 4 4GB, conveniently mounted on a bar across the two telescope rings.
And finally a close up of the rig.
