Well it's been 4 days now with clouds and rain here, Northumberland coast... the weather forecast was supposed to be 19deg and blue skies, yeah whatever!

How can the forecasting be so wrong...then again they do cover their backs with the words "changeable" and "hit and miss" 

From this day on I'm never looking at the weather forecast again, better off opening the window and sticking my finger outside!

Sorry for the rant 🥴

Yes best way to forecast the weather, what you see is what you get💨💦🌞

Hi what camera, mount, exposure etc did you use?

Fantastic image.im going to have to get me that 135 lens👍

Wot I said.

If the vendor doesn't know the difference then caveat emptor.....

Caveat emptor🤔

Ok thanks John I thought it too good to be true 🌠😭👍

Hi anyone got any idea, is it a meteorite or slag

Hi I use a large barbeque cover , leave  my HEQ 5 out all year round under it never had any problem.

Hi when you enter your date make sure you use the USA way ie month first then day.I made this mistake first time I set up🤔

HEQ 5 is a good mount at a reasonable price

I would say if the one you have made work's use it sometimes looks aren't important, unless you know what you are doing be careful I blew my eq5 pro motor control box  but that's me 🤔😭

Wish I had pupil as big as a cat's maybe we could save money by having smaller scopes🤔👀👀

Not really night yet, but all set up for first light tonight!

Do I see a cooling system on the dslr

I understand, but it is not really the sales pitch here - it is very old convention on how to label different sensor sizes.

If you visit that wiki page I linked earlier (here it is again: https://en.wikipedia.org/wiki/Image_sensor_format), you will see that most sensor sizes are in fact labeled as a fraction of that strange one inch which is 16mm and not 25.4mm as you would expect.

I do get your concern, and at one point I also myself wondered why they are labeled so strangely (although I never trusted that labeling and always checked diagonal in mm - probably because I'm used to metric and never think in inches).

Fact that Sony replaced term 1" with Type 1 - is also rather telling. I guess that many people noticed this discrepancy and that "Type" nomenclature is introduced to remedy this somewhat.

Yes all understood but most people don't know the history re sensor labeling it would be nice if things could be clear instead of using obscure interpretation in order to justify somewhat misleading information.I am not saying zwo is doing this to sell the 533,but things could be made more clear I am sure🙂

The glass tube that surrounded a signal plate had a 1-inch diameter, although the photosensitive area of the tube was only about 0.63" in diameter – or around 16mm

I failed to read this in Vlaiv's earlier reply, In TVs they only count the actual screen size, so yes it does seem strange. and misleading.

Reason I brought this issue up is because I bought a zwo 533 because they sold it as a1inch sensor.when it came hello it's 16mm. No problem with the camera just the sales pitch 🤔

But it’s not, a 60” tv measures 60” diagonal.  These sensors measure 16mm diagonal instead of 25mm.  If I see this I assume the sensor is 1” diagonal. It’s misleading in this image that they advertise with

 

Yes that's the point I to am trying to make and calling it Type 1 is no better

It's like TVs, they are measured diagonally too. They might advertise a 60" tv but is only something like 52" wide and 29" high.

Yes I get your point regarding tv but wouldn't it be nice to order a 60inch tv and get one not 60inch on the diagonal. It is really down to avertising sales

I don't know if it can be clearer than this:

(taken from ZWO website page on ASI533MC Pro)

You also have all other necessary information regarding light gathering potential of the sensor:

Yes I get that my point is don't advertise as having a 1 inch sensor when it is clear by looking at it it is physically not the case. if I buy a 80mm aperture scope I get a scope which is 80mm,not less.

Thank for the replies. I note that zwo now says it's a type 1  and this should clear things up.I understand the history of the sensor but saying it's a type 1 still leaves the1 in the advertisements.Perhaps we should be informed of the actual aperture of the sensor,as it is advertised with telescopes,then we know what we are getting for our money 🤔

ZWO publishes correct data.

I think that your confusion arises from the "1 inch" part - which is remnant of the old times and does not actually measure 1 inch in diagonal.

https://www.imaging-resource.com/news/2022/07/28/dealing-with-the-confusing-and-misleading-1-inch-type-image-sensor

This means that when you see something like 4/3 or 1/2" sensor size - you can't really calculate those in inches but rather see one inch to be about 16mm in this context.

Sensor that is 1/2" will have about 8mm diagonal.

(see this page: https://en.wikipedia.org/wiki/Image_sensor_format)

So in reality it's roughly a half inch that actually collects the photons.

Much as been said regarding the. 533 censer size but dose anyone know the actual size of the censer area that records photons when imaging, not the advertised size by ZWO.🤔

Well I know there not available much yet but I would consider a seestar 50 , or a Dwarf 2 , both are small and light , put them on a table outside sit indoors and look at the images on your phone or tablet.The Dwarf 2 is readily available now for around £400  seestar £600 . Hope you get back into it soon all the best👍😃

Yes modified is good for emission neb it dose make a lot of difference 

Hi again a modified is not the best for galaxy imaging 

Yes the arms are there , as it's been said I to think you push curve's and level's more ,also saturation but be careful with it . Play about with colour channels. You can always give it another try if you go too far with any process.👍
