AstroMuni

You should be able to make a start with your existing setup. Aim for the DSOs that fit into your FOV and learn the techniques of managing your scope & camera with software & understanding post image capture processing. I certainly find that the latter has the steeper learning curve. Using the data I have acquired, friends of mine who have more experience, can get vastly better images. Get a laptop with lots of storage and good processing power (in case you havent already got it). Good luck.

That makes sense. Get him to try out the hobby with bins first and perhaps get him to attend a local astro club. That will inform him of the options and budgets involved

I think I understand what you are saying and my interpretation of what vlaiv is saying is ...If you have a monitor at 600x400 resolution, the 6k x 4k image at 1:1 would overflow your computer screen and the image of planet would look like the image taken with 600x400 camera viewed at 1:1 as that image too would occupy your full screen. So in effect you are both saying the same thing 🙂

Wow @peter shah amazing colours. You have made the elephant look like a mackaw 🙂

Nice one. We just need to reduce our stars less using software 😉 and possibly not use the narrowband filters...Otherwise you would get something similar to Yerkes is my guess.

That looks good 👍

Heres a helpful post from FLO https://www.firstlightoptics.com/blog/cleaning-a-newtonian-mirror.html

@Rodd why dont you post the stacked fits files for each of Ha, Oiii so others can have a go at it. They should be able to advice you on the PI side. I use Siril and can certainly try that way too.

Yes, you should be able to use de-ionised water. Its purified water - just uses a different process to distillation.

Its looking much better now. What software are you using to integrate? EDIT: have you equalized the images before combining them?

Hi, thats odd indeed. Generally you end up getting more red than you want. Perhaps if you explain the process you are following to integrate the Ha that would help us understand better. It almost looks as if the Ha is getting mapped to wrong colour during the integration. Posting your unprocessed images would help too.

That looks lovely 😍 Good luck with applying the techniques mentioned in the posts above, to extract the outer nebula and look forward to seeing final result. Thanks. I use an OSC camera (ASI533mc pro)

Fantastic detail for just 1 hours worth of capture @Roy Foreman

An ADC (atmospheric dispersion corrector) filter would be useful for planetary. An IR/UV cut filter too, if you havent already got it.

Sorry for side tracking this topic.... Hi Simon, Thats an interesting setup which seems to be hanging onto your roof 🙂 How is it mounted please? Any images of the base would help.

Good point. I was making the assumption that OP would like to run everything off the RPi and was trying to highlight that the Astroberry repo doesnt have the newer versions of Kstars.

Others have given details above, so just adding to it. If you do decide on going down the RPi route, try out Kstars/Ekos and see if you like it. Great piece of software but like all good s/w there is a learning curve. Also Astroberry seems to be a dead duck at the moment, so suggest you try out either Stellarmate or AstroArch instead.

Luckily for us most of the default settings in Siril will get good results. Its only in the infrequent cases that we need to understand the options available to help get around it.

This might help https://siril.readthedocs.io/en/latest/preprocessing/registration.html

Indeed, they look quite similar. I wish I had all the filters to do a comprehensive comparison 😉 Thankfully S@N mag did one recently https://www.skyatnightmagazine.com/advice/multi-band-filters-astrophotography/

I did check and I have it the right way around. It wasnt meant to be a which filter is better OR the most suited for a particular target type of comparison. Its just what I had in my possession at the time comparison 🙂

Dont have the filter with me now as it was borrowed for the weekend. Will try again at another time and post pictures BTW, I did a quick comparison of the Antlia Triband vs ZWO Dual band and posted here

It was spinning around but when I attached stop ring it grabbed it.

I did try that with a borrowed filter. There is a thread but for some strange reason I couldnt attach the filter without adding the stop ring which meant that the whole assembly did not fit into the focuser tube.

Hi all, I had a chance to do a quick comparison between these two filters and thought I would share it here. Both sets of images (30 x 60s) taken on the same night with setup of SW130pds + ASI533MC Pro with gain 240, offset 70 and -5deg. Stacked + Background extraction done in Siril followed by Autostretch. With Antlia Triband https://www.firstlightoptics.com/antlia-filters/antlia-triband-rgb-ultra-filter.html With ZWO dual band https://www.firstlightoptics.com/narrowband/zwo-2-duo-band-dual-narrowband-filter.html
