gonzostar Posted August 28, 2018 Share Posted August 28, 2018 Hi After my recent heart scare, that may or may not have caused my mini-stroke. I was thinking of imaging the Heart Nebula with my set up. I have a unmodified canon 70d camera and shall be using a IDAS-D2 LP filter. A 102mm APO refractor on a avx mount. Using 300s exposures. Will this pick out the nebulosity? The crescent Nebula which i posted had a total integration time of 21 hours and still faily faint. . Would the Heart nebula still requre this amount of time or would i just be waisting time? Cheers Dean Link to comment Share on other sites More sharing options...
wimvb Posted August 28, 2018 Share Posted August 28, 2018 I think you will only capture the outer regions. To image the detailed inner stuff, you need either a modded camera or nb filters. Oh, and dark skies of course. Have a look on astrobin to get an idea. Link to comment Share on other sites More sharing options...
gonzostar Posted August 29, 2018 Author Share Posted August 29, 2018 Ah thanks for that info Wim. I will think of another autumn target. Having got a image of the crescent nebula (faint), i thought i had a chance of the Heart Nebula. You have saved me alot of time, Cheers Dean Link to comment Share on other sites More sharing options...
wimvb Posted August 30, 2018 Share Posted August 30, 2018 The North America nebula, especially the Cygnus Wall ("California" area of the NA neb), is possible with an unmodded camera. So is the real California nebula, later this year. With an unmodded camera, you need a lot of subs to make up for the weak signal. Link to comment Share on other sites More sharing options...
gonzostar Posted August 30, 2018 Author Share Posted August 30, 2018 Cheers Wim, I will try North America target next summer. In the mean i am attempting the Veil. Now we are entering a month with a R init, what is your next target? Dean Link to comment Share on other sites More sharing options...

We've just moved and there are still boxes everywhere. On top of that is a cloud cover. But I will try some target in Casseiopea probably. And later on I want to collect more data on M110, plus some dwarf galaxies. My sky is about 2 magnitudes darker (on paper) than before, which puts faint targets within reach.

gonzostar Posted August 30, 2018 Author Share Posted August 30, 2018 That sounds cool. Will look forward to seeing the results Link to comment Share on other sites More sharing options...
Galactic Wanderer Posted September 1, 2018 Share Posted September 1, 2018 Rosette nebula also could be an option - had decent success with it with an unmodified camera from London.

Interesting about the North America nebula Wim - Tried this target out but found it hard due to the faintness and how spread out it is. I will definitely try it again this spring - now that I have a modded camera - fingers crossed with darker skies. Link to comment Share on other sites More sharing options...
ollypenrice Posted September 1, 2018 Share Posted September 1, 2018 There is a very simple Photoshop trick which will pull out Ha from all Ha targets but which is particularly useful if you're short of signal. Just go to Image-Adjustments-Selective Colour and it will open by default in reds. Move the top slider to the left to lower the cyans in red. That's it - but it can make a big difference.

gonzostar Posted September 1, 2018 Author Share Posted September 1, 2018 Thanks Olly thats certainly worth ago, I recently did a total of 21 hours on the crescent nebula which i think worked out, although a little faint. I think the same is called for if i go for the Heart. Link to comment Share on other sites More sharing options...
widotje Posted September 9, 2018 Share Posted September 9, 2018 If you can spend some money, I would advise to modify your DSLR and buy an Ha clip in filter. It will certainly bring out the heart nebula, no matter where you are, even in a red zone. Link to comment Share on other sites More sharing options...
gonzostar Posted September 10, 2018 Author Share Posted September 10, 2018 One day i will have hopefully saved enough money to go mono with filter wheel! Although i am happy with the canon 70d so far Link to comment Share on other sites More sharing options...
