Why do so many people use reducers with sct's i mean isn't the focal length the reason you bought it.
@DSOImager 7 күн бұрын
There's a few different reasons. For me it's mostly about the speed, F7 vs F10. F7 will produce a brighter and more detailed image for the same total integration time. Also the shorter FL and larger image scale makes the whole rig more forgiving, suitable for a non premium mount like an EQ6 with average seeing conditions. And 1440mm FL is decently long anyway. You're not going to find too many other scopes out there with 1400mm+ FL at F7 for this price.

The AVX was my first mount and I admit I had problems at first. Mine is very capable of great guiding. It wasn't always the case though. I now use a mini PC with CPWI, N.I.N.A., and the star sense auto guider. With that setup I get just as good of guiding as my EQ6r pro. Main thing I've found is don't overload it. Mine came with an 8" Newtonian that, in my opinion, was way to heavy for photography, even though it was marketed as such. With my Redcat 71/QHY183 setup it does great at 5min exposures. One issue I still have is you have to remember the combination to plug in and turn on everything or CPWI will give you issues connecting to it. I wasted quite a bit of time to figure that out...........

Thanks for sharing your experiences. A redcat 71 is pretty much perfect for the AVX. :)

Hi! I am just starting out with this hobby and got a rig together around March 2024. I was able to get a nice small refractor, guide scope, strain wave mount, Windows mini computer to run N.I.N.A., EAF, and I had two small uncooled cameras to start off with. I live outside of Toronto and wasn’t expecting much in the beginning. I was going to try OSC on broadband galaxies and try Ha on the mono camera. I expected very little in Bortle 8/9 skies. I was blown away by being able to image some nice galaxies and it completely changed my expectations. I decided to continue with OSC and bought a nice 533 cooled color camera. I just have to learn how to properly process the images but it is all seemingly coming together. Never thought I’d be able get a rig working overnight from my backyard and allowing me to sleep while the rig is working hard all night so quickly. Many thanks to all the great resources on KZbin. Thank you for your insight on OSC vs mono it now makes more sense as I discover what is possible.

I have a totally different experience and do not agree with your conclussions. I have an AVX that I purchased last year (2023). I have an Edge HD 8 mounted on it. I use a HyperStar, an ASI183MM'pro with a filter drawer, an ASAIR Plus 256 GB, an ASI220mm guide camera, the Celestton GPS SkyAlign, along with the PLL Alto and Giotto, and the StarSense. I have had no issues with it tracking. It does a maervelous job. I ran into some of the issues you mentioned, and it was the ASAIR Plus. The problem was that whenever I entered into the ASAIR from my tablet, it was getting the wrong location coordinates, even when I manually entered the correct ones before connecting. Now I enteer frm my phone, which has the right coordinates, and since, it works beautifully and at the end, it parks my mount at the home position. There is a video from Astrobender on the process to get it right with ASAIR, and he is gott it right. When I use it with the Eagle5 and using NINA and CPI, I use the StarSense Autoguider and have zero issues. It guides and moves smoothly. I take exposures anywhere from 30 to 120 seconds long, depending on the target, and rarely have to discard shots (most of the time, it is because shooting stars or the police chopper just getting in the way). Lastly, you can set RA limits in the mount via the hand controller or via CPWI.
@DSOImager 24 күн бұрын
Good to hear that your AVX is working for you. Running hyperstar and keeping the subs short certainly helps. Also good to hear about the mount limits. Does it hold those values after being powered off and unplugged or do they need to be entered everytime at start up? I imagine CPWI would hold on to it. I do stand by my conclusions. We can agree to disagree :) Clear skies!

Like JWCarr, PixInsight no longer accepting the EZ resource you recommended. It looks very good. Is there a workaround to getting this resource. I enjoy your teaching, James, and please throw another lesson our way. You really are a good PixInsight guide.

Thank you Roger! Yea.. sadly the EZ scripts are long gone. I have not found a good one click alternative to the Auto Stretch function. I currently use the GeneralixedHyperbolicStretch tool. It's a little tricky to use.. but once you get the hang of it, its much better. I should do a refreshed beginner processing video. Thanks again :)

Q. You actually started with a "Baby Sized" 70mm scope? W O W ! I know plenty of folks that began with an ancient or even homemade 6 inch Newtonian. But a 70mm ? I'm speechless!

Looks like you had a short window of time to capture this amazing target. And the final image rocks. I live in the Southern Hemisphere and to be honest, I think the Andromeda galaxy looks awesome (which we can't see most of the time here.) Though someone else here in Australia did manage to capture the Andromeda galaxy at some point in the year when it was close to the horizon. The clarity wasn't great but that was to be expected. Still, he succeeded and that's the main thing. I would like to photograph the same subject - I'll have to check if it's possible from my latitude on Kangaroo Island in South Australia. Alas, I have no telescope or star tracker. Just a regular mirrorless camera with a variety of lenses and a tripod. Hopefully, shooting a whole bunch of light frames with calibration frames and stacking might produce something half decent.

Thanks! Good luck with your Andromeda shot if it gets high enough. It is a bright target.. so if you can get it framed up you should be able to capture something. :)

Great information!! I do have a question. If I invest in the filters for the one shot camera, do they carry over to the monochrome if I upgrade at some point? Or are they completely unnecessary when doing a monochrome camera?
@DSOImager 2 ай бұрын
Duel/Tri/Quad and similar filters are not needed with mono. For example, a dual band filter that passes Ha and O3.. with OSC you can separate the data (red= Ha, Blue/green = O3). With mono, all that data is grey scale.. so no way to split ha from o3. You can use it.. some people have experimented by using such filters to act as sort of a lum layer for narrowband data.. but I don't think there is much gained verse running single band filters with the mono sensor.

Question about connecting the AVX. does the central rod/screw connect with the plate or is the whole too big? Thanks
@DSOImager 2 ай бұрын
The central rod that goes through the accessory trey and screws into the bottom of the AVX mount also screws into the zwo plate/adapter.

What about dew challenges on the corrector plate? I see you are using a dew shield. Do you need to use a dew heater? If so, does that affect star size/shape as others have noted?
@DSOImager 2 ай бұрын
Yes, I am using a due heater strip with the dew shield. I have the heater strip on top on the dew shield, right at the corrector plate. I had my doubts that this would actually work... but the only time in the past 4 years I had due on the corrector plate was on a very damp night and I had forgotten to turn the dew heater on. In regards to star shapes.. no I have not noticed anything. In fact, if the wind is over 7mph I'll remove the dew shield. All the data gets stacked, with the same flats even. What I do notice with star shapes.. is that my Edge takes longer to cool or equalize than my 115edt and it's noticeable on the star shapes.. usually after an hour the star shapes are back to normal.

Hi there! I wanted to let you know that I watched your video and found it very informative. I noticed that the AM3 mount is currently on sale, and I'm interested to know your thoughts on this mount and what payload capacity you would recommend. I'm planning to start with EAA and do some light astrophotography after many years of just visual observing. I recently bought an S50 and am no longer interested in visual observing. I want to keep my setup as light as possible, so maybe a refractor or a 6" SCT. I'm eagerly waiting for your thoughts on the AM3 mount. Thanks!
@DSOImager 2 ай бұрын
Hi Frederick! I think the AM3 is a great little mount and is perfect for smaller refactors. I think it's totally doable up to a ~4" refractor. As far as a 6" SCT goes.. it can handle the weight no problem but I don't know if it will guide well enough at longer focal lengths. Maybe it can but I've only used a 65mm refractor with mine. An AM5 might be a better choice for the extra capacity.
