The Heart Nebula (IC 1805)

[Joeistotalycool]

I was out last night and managed to capture 13, 10 min frames on the heart nebula in h alpha before I had to pack up (school next day) 2H10M Exposure 

Skywatcher Evostar ED80 Ds-Pro

Celestron CG5 Advanced GT

Canon 1200D astro modified DSLR 

Baader 7nm Ha filter (1.25'')

No autoguiding

Hi Joe, that is absolutely superb, well done!

[Galen Gilmore]

Very nice image! What amazes me is how you were able to get 10 minutes unguided! 

I couldn't get that with just a camera and lens!

[Craney]

That is very well framed.   

I usually get the 'Ear' or  'Cup Handle'  Nebula.... ie  50% missing.   ( btw  I avoided the Half Hearted pun )....

Thanks. I had accidentally knocked my tripod so I had to realign and I just got it right

Wonderful.  What sort of adapter are you using to allow the use of 1.25" filters with the DLSR?

[Star101]

Great shot. Well framed.

 

Thanks for sharing.

V-good, its nice to see so many people doing ha with DSLRs at the moment.

I am the basic celestron Barlow/t adapter attached to the 2''eyepiece to 1.25'' eyepiece adapter supplied with the skywatcher evostar ED80.

Its just a convenient way to get around street lights and dreaded moonglow

Normally you would avoid using a 1.25 inch filter with a DSLR as it will cause bad vignetting. The normal connection method is DSLR-T-Ring-2inch nose piece, then using either a clip filter or a 2 inch filter.

Yea, I would have gone for 2'' but my budget unfortunately does not allow me to get them  

Flats seem to solve most of my problems though

I use this one:

It seems to work well enough and I will probably use it until I get a filter wheel.

Its good to have a set of filters for when you move on from the DSLR, something I am yet to do myself due to budget considerations. Depending on the target I think you may struggle to get good SII signal but OIII should give you some data worth working with, I did find the signal OIII signal in this target very faint though when I did it with my DSLR. Had to use some very long sub lengths.  

The Barlow will reduce the vignetting by narrowing the light cone, probably why you are managing with the 1.25 inch filters. But it will greatly increase your exposure times assuming that is a 2x. 

All in all such difficulties, makes your image even more impressive though.

OIII may not be to much of a problem for me, as I am planning on making a HaRGB composite image. I'm doing this because I have not a clue how to map colors to any false color palates on Photoshop :/

I thought you maybe had some modified adapter to keep the 1.25” filter as close to the sensor as possible. Good to see that the nosepiece/adapter you are using works very well.

Very nice result
