As I am ready to invest in this new CMOS camera from ZWO the Asi2600mc pro , I am trying to understand why this camera will be better than a DSLR with a filter Infront....
How this camera will give me better images ?
I have used DSLR camera some years ago , when I was starting this hobby but after that I have been through mono ccd's , since the time I realized that unfortunately due to lack of time I can not continue with mono imaging and filters....
So I am thinking to give it a try with a brand new, let's say technology of Color CMOS and see what I can get out of it....
I see some really nice examples on the net but am I going to achieve them ?
The Zwo Asi294mc pro widely used around the world is also very promising...Discontinued already as I hear...Amp glow issues....is it really so annoying ?cheaper than the new asi2600 MC pro by half price....
So can someone persuade me that the Zwo Asi2600mc pro is better than the others ? 🤔
Can I please ask, is there anyone out there with the following or a similar setup to this:
William Optics Z61 Scope + WO 61A Flattener + ZWO ASI533MC Pro (or other ZWO Camera) ?
Currently, I have been using the following setup:
William Optics Z61 Scope + WO 61A Flattener + Nikon DSLR
However, by the end of the week I am hoping to have this new setup:
William Optics Z61 Scope + WO 61A Flattener + ZWO ASI533MC Pro
I was really just wondering how the more experienced out there had configured/connected their equipment together?
How people connect their ZWO cameras to the flatteners?
Are the flatteners still required with the smaller sensor cameras ?
I was just wondering if anyone has any pictures of similar setups to above please (equipment trains)?
Thanks in advance for any comments or advice.
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.
Question, is my pier out of level if I'm trying to PA (with asiair pro) and both directions are moving when I adjust the alt bolts? I can't get the mount polar aligned.

How can I set up APT so that it always connects by default to my imaging camera? I have an irritating problem that APT will regularly connect to my guide camera, even though that camera is already connected in Phd2.
I have created two APT shortcuts on the desktop, one specifying camera 2 (which usually is the guidecam) and the other specifying camera 1 (which is usually the imaging camera), but it looks like cameras 1 and 2 are not absolutely assigned to the ASI1600mm (imaging) and ASI290MC (guiding).
At APT startup, in the log it will say 'Connected to ASI1600mm' and then imediately say 'sensor size 5.6mmx3.2mm'. Then I know I have a problem as it's obviously not the 1600! I can usually sort it out by disconnecting, Shift-Connecting (to get the camera selection dialog), and selecting cameras 1 and 2 until I get the correct sensor size.
There must be a better way?
