M31

Happy with my previous image, I thought I’d have a go at the galaxy next door to it—-M31, Andromeda.

This is the same set up as the M33 image so the same FOV. Just shows how big M31 is! This is 6×5 minutes in RGB and 3×5 minutes in L. 1hour 45 minutes total. You will notice some odd shapes in the stars. This is down to me not refocusing between filter changes. Still I know better for next time.

M33

Decided to change my guiding system. Instead of using either the Takahashi or the RC I’ve bought a new dedicated guide scope. It’s a 50mm f3.8 guider/ finder scope. Searched the internet and found a brand new one for less than £50. I’ve teamed it up with the Atik 450. I haven’t imaged M33 for some time so I thought I’d test the guiding on it. Setting the scopes up to be in the same FOV proved more simple than I expected. Having quickly focused the Tak I set up the imaging for 5 minute exposures and took 12 guided images. Stacked in DSS processed in Fits Liberator and PS6, this is the result. This is the best guiding I have ever achieved. The stars show no sign of trailing so I am hopeful that I’ve solved a lot of my previous problems.

Pegasus Dwarf Galaxy

Hi All.

This is the first attempt at the Pegasus Dwarf Galaxy. Believe me it is there! It’s very faint just to the right of the ring file re-enforcement ring in the middle.

I couldn’t work out where the dust bunnies had come from as I had cleaned the filters and the the camera.

I then took the filter wheel apart and cleaned it all over again, plus the filter and the camera.

Result!!

The second image is 2 hours of luminance in 5 minute subs.

There are 2 other galaxies in the image, one at 16.5 mag, the other at 16.7 mag. Can you spot them?

M57

This is really a test for alignment of my “new” scope with my Takahashi two nights ago whilst trying to get the two telwscopes to point at the same object. I completely messed it all up and lost the RC image. So last night after some 2 hours of fiddling, I managed to get it back so that i can see it. The focus is off but I’ve just got a new Bhatinov mask so hopefully it should be a bit better in future.

So this is M57 (the smoke ring). Although out of focus you can still make out the 3 stars in the centre. Also in the 3.30 (clock face) position is the galaxy IC1296. This has a magnitude of 14.3 and size is 1.1′ x 0.8′, so I’m impressed with what I have achieved (just have to do better with the focus!).

M51

Well it’s not as good as I would have liked, but given the conditions over the last few nights with the”seeing” not too great and my first attempt at RGB with the new scope I have to be fairly pleased I haven’t wasted my money!

Focus is a little out but I’ll get used to the small adjustments eventually.

The technical details are: as before for the scope and guiding.

Red:17x 5 minutes

Green: 18x 5 minutes

Blue: 18x 5 minutes

Luminance: 24x 5 minutes

First Light 6″RC

This is my first attempt with my new iOptron 6 inch Ritchey Chretien. It took a while to get the system to work but I managed to get 30x2minute subs in Luminace. Stacked in Deep Sky Stacker, then Fits Liberator and finally PC. (sorry about the dust bot, but I was more interested in getting the system to work). The final image has only about a 10% crop, so this is pretty much the full field of view using the Atik 314L+. I’m pleased with the image as the focusing is a tad fine so I guess I’ll have to look at getting a motor focuser. I’m going to add colour as soon as I can.

New System:

iOptron 6″ RC @ f9 with Atik314L+

Guided by Takahashi Epsilon 180 with Atik4021 !!!!!!!!!

Filters 1.25″ Astronomic

SH2-290

Hi,

Another attempt at using the Straton software.

The target is a large Planetary Nebula in Cancer. However, as always, it is quite dim. Only used the Ha so far but it does take a good narrow band. This was using the Atik 450 before it was sent back to the maker.

Total time on this is 1hour 30mins over 3 nights.

As before, having stacked in DSS and then Fits Liberator, the image was put through Straton to remove the stars. The remaining image was sent to PS and Stretched as much as I dared. Then the stars were put back and the result is above. When I get the camera back I’ll be adding more Ha and the O3 &S2 (That will probably be next year!!)
