I spent the early part of the evening refocusing the guide scope which was a bit frustrating but did it in the end. I wasn't going to do anything else but my wife mentioned that the stars were excellent when she came back indoors from being walked around the garden by the dog. So instead of going upstairs like a good boy I grabbed the Startravel 102 and got excellent views of Jupiter with belts showing beautifully (I must have left a blue filter on!). The best view of all was of the Pleiades. I suddenly realized that I could see them with my naked eyes so putting the scope on them was easy. All I can say is that the sight was breathtaking!

Thanks for that, I'm now trying to learn how to process dual narrowband images from an OSC camera in Astro Pixel Processor and not PixInsight. I've found a suitable video so I'll proceed with that.

Same image with stars removed and background extraction done, just for fun!

Another session last night, same gear but with L-Enhance filter instead, 200x60s subs, no calibration frames.

I did download it but couldn't open the zip file! Extracted it now.

It's the massive number of stars that bothers me but you're quite correct about the amount of data.

I finally managed to get something out of it, can't say I'm particularly impressed with it!

Novice imager here, I have an asi533MC pro camera and I've used it with my Askar FMA180 scope in the past using an Optolong L-Enhance filter. The images it produced had some blue fringing and I was advised that the colour correction is less than optimal and to use an Astronomik L3 luminance filter to correct this. Last night was my first opportunity and I got one hour of NGC7000 in before the clouds, 60x60 second lights, no calibration frames (yet). The ASIair produced AsiFitsView files, a text document and a JPG file for each sub. When I look at the JPG file in Windows Photo viewer I can see mild red colour in the nebula. I stacked the AsiFitsView files in both DSS (which I've just started learning yesterday) and AsiStudio DeepStack and to my amazement it produced a greyscale image! I'm now assuming that's exactly what a luminance filter does. So my question is how do I finally get a colour image. Do I make another set of subs with my L-Enhance filter? If I do how do I do this in the same imaging session and can I then process both the luminance images and narrowband images together?

I'm a relatively new user of the Asiair, I have the Pro version but the functions are essentially the same. Apologies if I'm misunderstanding your problem but when I first got the Asiair I found this YT video very helpful in going through all the steps necessary for the Asiair. I also use the Asi533mc pro so I don't use a filter wheel so I just skipped through the bits about the EFW. https://youtu.be/C43xWCLm1fw?si=nNWUQ6gmYIDRZ4kF

Can you give us some more information? What mount are you using to begin with?

Our dog loves going to France, fortunately he's a good traveler in the motorhome. You'll have to be prepared to shell out cash for the obligatory Animal Health Certificate which costs us about £180 each time although that is variable depending on where you live. Also you have to take the dog to a vet before you return home which can cost anything from 30 to 60 Euros.

Not wishing to hijack the thread but possibly something that may be of interest to the OP. I am a novice for information, I also have the 533mcPro camera. Should I choose to use different filters during an imaging session can these be integrated in software such as Siril or APP? The reason that I might want to do this would be to eliminate star bloat in a certain refractor and also bring out nebulosity by using an Astronomik L3 and an L-Enhance in the same session. If I'm talking out of my rear please put me right!

I find the campsite lighting in club sites very distracting so we spend more time these days using club Certified Location farm sites. They are only allowed to have 5 units on site, have minimal ground lighting and have much more space being situated in fields.

I set up last night in the usual way, Evoguide 50ED with dew strap in place, asi224mc with uv/ir cut filter on an Az GTi using Stellarmate. After the usual Stellarmate nonsense I got images of things like the globular cluster in Hercules just fine but any attempt on a gaseous or planetary nebula was an utter failure from an image point of view. Whereas in my last session a few weeks ago I was getting lovely images of these objects very quickly but not last night, just a light fuzz to show I might be there. Target acquisition seemed perfect and bizarrely I got Jupiter dead centre and although no more than a large dot I saw 3 moons and Jupiter surface features. The one thing I noticed was that everything was quite wet and a quick check showed that humidity here was 93%. Could this have been a factor?

This is exactly what I have done, fitting the Skywatcher electronic focuser enables almost vibration free observing. However it's not that easy to fit the focuser but a chap on YouTube called Vasco Ribiero in Portugal has a solution which I bought from him and it works perfectly.

I have both the Baader zoom and the Svbony zoom. I only bought the Svbony zoom because it fitted my mobile phone adapter. Although subjectively the Baader is 'better" I use Svbony now with my Mak127 to get the planets in view before imaging and it's absolutely fine, if it were my only eyepiece I'd be perfectly happy with it.

Thanks, I don't think a bigger aperture scope is on the horizon, apart from the cost there is the weight to consider.

Well, I'm something of a novice in planetary photography so I would say that you would get an image but I'm not sure it would be a good one. I'm using a telescope with a focal length 3 times longer than your lens, a dedicated planetary camera and a Barlow of 2.25x magnification and the resulting image is just about large enough for post processing.

It's possible, why do you think it may be the Barlow. It's a pretty good quality one if that makes any difference. Possibly a Powermate would be better?

My Domestic Financial Controller would kill me 😀

Yes I am imaging Jupiter quite high in the sky, I'll take a look at my colour balance technique in Registax.

Thanks for the replies everyone, most encouraging. I think my video images were too dark to avoid blowing out the highlights. Looking at YT tutorials their images were brighter. @Cosmic Geoff, I'm not clear what you mean by getting the clouds belts horizontal and de-flipping the image. Would an ADC help with the blue fringing? @Kon, I started looking at some YT tutorials for Astrosurface, thanks for the tip.

I made my first image 2 nights ago which I won't show😄 but I made some more last night which were much bigger video files. If possible I'd like some critical feedback. Equipment: Mak127, ASI224MC with Baader Hyperion barlow, Az GTi mount. Processed in PIPP, AutoStakkert and Registax, finished in DxO Photolab.

When setting up for an imaging session and giving the refractor time to cool down when should dew heaters be turned on, while the tube is cooling or when imaging session starts?

Thanks for that. I'll play around with a few of those options.
