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.
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.
Followed up last night with M27 (the Dumbbell). This is 10x5minutes of luminance. This is the full FOV with the new set up. It takes a bit of time getting it in view as I still haven’t managed to align it with the Takahashi.
I’ll clean off all the filters again and add RGB when I can.
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.
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?
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!).
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
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.

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!!)
