The lens on my zwo then unscrews from the black collar which is a M78 to M42 adaptor.

I can't see the blemish using a mobile phone, blemishes can often be dust bunnies, how they look can help indicate where they are.

That's lovely to have caught a moon shadow, when you think about what that is it's amazing.

When I view this on a mobile phone Jupiter has a grid pattern like it hasn't debayered correctly.

You can enter all your details of kit in here with a selected target to understand the FOV you would get. The link is from the resources tab top of this website.

I had edited my post as I added achromatic as well, which are not apochromatic but both can be doublets.

Achromatic are not corrected on blue.

You can have doublet Apochromatics such as skywatchers ED range. And doublets that are achromatic

If you have an android device and your particular canon is supported then the app DSLR Controller works really well.

Hi during the day use your telescope and camera and focus on a really distant tree or arial (no where near the sun) infinity focus is just that and the Moon or Jupiter would be in focus if you don't alter anything.

Or make a bahtinov mask (or simple Lord y mask) and use that to focus on Jupiter, or a bright star, with your telescope and camera.

Whether Jupiter is steady is down to seeing and atmospheric disturbance. Generally video is used and not stills as then you get many many more frames to hopefully get some frames where the planet is steady. This video you then process in something like Registax.

In auto dev reducing outside region of interest influence and increasing the ignore fine details can help you control the strength of stretch reveal.

Could down load the affinity trial and see if you can do what you need to do, there are astro processing videos on you tube made by affinity staff and they appear to be adding functionality all the time

In order to offer help it would be useful if Candela added a jpg to their post of their process so we can see the image in the post directly, I think you will get a lot more help if you did this and also added what software you had used for your process.

Saw this thread and saw a relevance to your thread.

I reported the really bright one I caught and I keep meaning to report the others I catch but haven't yet.

Samyang 135mm f2 lens gives lovely wide views, there's a thread on it

When I did a fiddly mosaic I stitched it in batches using ICE

For free Microsoft did a great app called ICE image composition editor (I've read reports it might have been withdrawn it's a W10 program)

Infinity Photo I think has done a youtube on an astro stitch.

Was the reference frame used on each matching stack perhaps different, does PI let you pick the reference frame for stacking.

Do the individual panels show the same edge distortion?

Hi, great to see a static tripod used you've captured quite a bit.

I found when I did a similar exercise of 100 x 6 second images I needed to split this into three sets, I used the middle frame of each set as the reference frame in deep sky stacker.

You'll get three images to process but the edges will be less distorted if you had found this the case so far, the final three can then be joined using something like Microsoft ICE, you'll get a wider final image then crop the top and bottom of desired. I had used a 24mm lens rather than a 50mm.

Many infinity photo or photoshop astro processing videos can be followed using GIMP.

In startools to create a star mask go to Mask then select Auto and then stars or fat stars and Go to create a quick star mask. Could do print screen to save a reference of your process while you use the trial.

Totally. I've got several single frame really bright blobs and your post confirmed to me what they were.

The other 150p mirrored altaz goto is the skyeatcher star discovery which has been out for longer.

Nice to see that meteor captures can be head on and aren't always a streak. Looks very bright that one.

I should have added I do have a graphics card and it is that which drives the great colour rendition, using the inbuilt intel graphics chip isn't bad but it is not great.

Great image, love the beach huts. What lens did you use please,  thinking of your 30 second exposure and neat stars.

Using an LG 22M47VQ 1080 * 1920 native display, the dot pitch is great at .248, it is not large as do not have the space, loads of connections and clear bright screen that displays the full grey scale grades enough for my needs.
