Great! Probably the best image of this I have seen.๐ Geoff

Nice image๐ I had a go at this object in 2009, using my kit at that time of Vixen R200SS and Atik camera. I was surprised to see what I thought were 2 extra arms of the spiral starting from half way up the centre. It took a lot of investigating to find that there are actually 2 galaxies one on top of the other: NGC4236-1 and NGC4236-2. Maybe this accounts for the extra arms. Geoff

Nice one Peter. What bandwidth are the Ha and O3 filters you have used. Geoff

Great image.๐ AND you can just make out the soap bubble below the crescent! I still haven't managed that yet.๐ค Geoff -
May I make a suggestion? Before puting all your gear together next time, give the camera lens face a quick clean with a lint free lens cloth. The black circles on your images are out of focus dust particles which is usually a sign that they are on the camera front. I only know this because I have the same problem!!๐ Geoff

Lovely clear soap bubble.๐ค What bandwidth are the narrowband filters you are using? Geoff

Now that is a great improvement. The star reduction has brought out some fine detail in the gas fields.๐ Geoff

OK. I was looking in the wrong place!๐คฃ

Hi Damian, Can you indicate the star that is orbiting Cygnus X-1?๐ค Geoff

Had the same problem 10 years ago. The object was catalogued in the 1930's, but it wasn't given the correct location.๐คจ I don't now remember the details but its given location works out as being in the centre of the Pelican Nebula !! which when you go to it, there is nothing there. A search of bright nebula catalogues should give you the answer. Geoff

Thanks for the info. I should be able to get something then using my Tak Epsilon at f2.8 and my Bortle 5 skies. I think the only thing missing is the amount of data, I've only managed to gather 12x 300sec so far in O3 due to the cloud gods not playing ball!๐ซ Geoff

Great image. Can you give me some more detail on the filters? I see you have the Astronomik NB but what are the bandwidths. My Baader 4.5nm doesn't seem to pick up the squid. Geoff

NGC 4236 - Barred spiral galaxy in Draco
Spitfire replied to ONIKKINEN's topic in Imaging - Deep Sky
I like your images but I prefer the first without the rainbow. You're right, it is quite faint at Mag 10, but what is interesting is that there is another galaxy that sits on top of it (NGC4236-2) at mag 15. I took an image of them both some 11 years ago with my Vixen R200SS. It took 23 hours in Luminance and my processing then was even poorer than it is now! But just to show how technology has improved since then, I have attached my image from then. I think yours with just 5 hours is far better then mine, and you're right that some more data will improve it further. Geoff -
Very nice image. Tracking looks spot on with 1800sec exposure for the OIII. Which one of the mounts did you use for this? Have tried this myself with a 6inch RC but only have a few hours on it..........not a patch on yours! Geoff

Hi Carol, I think that is a great image, especially from Bortle 8 conditions. Not only that, but you have found the Geko even though it is nearly 1 degree north of the designated SH2-126 area. This is why it took me 2 years to find it!๐ฅด Geoff
