That is a marvellous first attempt. Congrats.

Here is a 13' 30" (27x30") shot from last summer. Probably the only half an hour I could use to do some astrophotography!

Thanks @vlaiv. It was professionally modded and IR should not be a problem, in principle. I will give the camera a new go on the next clear night here in Oslo, probably 2050.

Hey Michael,

Thank you for your reply. That might've been the thing, yeah 🤦‍♂️

Great piece of advice. I tried the other day with a kindle and I think it worked alright.

Will give this a go at some point, thanks!

Excelent first!

Hi everyone,

I have two master darks: one pre-mod, one after-mod. I can see certain pixels matching, but I fail to understand why that change happened or even if it's related? It bothers me how good/even the sensor was before, and how incredibly bad the center/left is now.

I can't seem to remember any other change the camera has gone through.

Any thoughts?

Thank you!

Ruben

Fully agree with Zermelo here.

1. "Turn left at Orion" +1
2. "The urban astronomer's guide" +1

And I also would add "Stars" by H.A. Rey just for the marvellous Part IV on the "why's and how's" (polar star - latitude, ecliptic and seasons, time-zones, etc). I found the explanations in that book to be really helpful on my understanding of the sky.

The only complain I have about TLAO is the sheer size of it, but as long as you're not planning carrying it around it should be fine. I seem to remember there was a smaller size version available, but can't really remember.

As for TUAG, I really liked the explanations on how different factors affect the quality of the sky, and also one learns so much about light pollution, how different types of street lights make certain filters needed/useless, etc.

I own a non modified Canon DSLR, a Skyguider Pro and a Zenithstar61 APO. The thing is I am getting slowly into the autoguiding realm, and even though I don't mind staying "manual" for a while, or not having DEC guiding available, I know I'll need a proper mount at some point. I was planning to get a EQ5 in the near future, but this winter has been horrible, so...

Hi guys,

So I've got an offer that includes:

Skywatcher EQ6 Pro + Skywatcher Evostar ED100 APO + 700D astro modified DSLR for around £1000. All bought around 5y ago. The thing is I imagine it is a very good offer, but can't make up my mind because all I was searching for was a modified DSLR! I do have a car to move around, so carrying an EQ6 mount wouldn't be that much of a problem.

What are your thoughts?

Cheers!

M42 is tricky because it's got a very bright core and then lots of interesting but fainter nebulosity around it.

How true.

I like both images

Hello from Oslo, Dan

My very first image of the Orion Nebula! This is the first time I am actually happy about my tracking (we reached -15°C so my laptop died in no time, leaving the skyguider alone), about the data I managed to get (1.5h) and about the post-processing. So exciting!

Taken from Hurdal, a place relatively close to Oslo in Norway.
