oh yeah it is never saw it

It’s a canon dslr, but modified so the sensor is quite a bit more sensitive.

It’s possible but it may be tough. The 130pds is great I love mine, but this target is full of tiny faint galaxies. 130pds will struggle on these faint objects, also the wider field of view of the 130pds means these small galaxies in my pic will appear even smaller If you are a novice, as you mentioned, I would use the 130pds on brighter bigger subjects and play around. Try the M51 or M101 have fun!

ah yes of course. 60 x 5min lights, darks/bias/lights calibrated. Canon 550d with Skywatcher 250 Quattro CF, Mounted on Neq6 Pro, ZWO ASIAIR did all controlling.

Getting fixated with the Coma cluster. It is just magical, just how much space and time are we looking at here with this photo added another 2 hrs to it now totalled 5hrs, and drizzled x2 to get more room to play when processing, my Stone Age laptop was little slow on the 700mb original TIF. I think this is as far as I will go. I got more faint tiny galaxies’ data to play with after the additional 2hrs

I won’t recommend it, same way I have never heard a Cheshire eyepiece used on a catadioptric

The acrylic is transparent. There isn’t a 45* cutout , the concept of the concenter tool bypasses the need of one. But, there is a glow-in-the-dark version of concenter now

Couldn’t agree more. The pain of shooting with dslr is that I cant control the temperature and shoot darks at a later time. after 3 hrs on the lights, it’s tough to stay up another hr and half to shoot the darks. but it really is worth the effort. I brew a cuppa, and watch an episode of something to keep me awake

Want to expose this tool called “concenter” that was introduced to me by @Captain Magenta. It’s not talked about too much surprisingly, and I cannot find much info on this tool on the net. Costs £70-ish posted from Germany’s TS-optics. It is a transformative collimation tool that will get your mirrors about perfectly aligned, if you don’t want to spend £00+ on Howie Glatter or Catseye Little under 2 years ago I was thrilled to get a 10” F4 Quattro CF reflector from a SGL member, I was very much into imaging already with my 130pds. Then I hated my 10” Quattro ! I heard it is hard to collimating, but I had plenty of mirror fiddling experience with the 130pds and a big visual dob. If it wasn’t for its dazzling good looks and girth, I would have sold it by now Then I was lent the “concenter collimating 2’ eyepiece” to try out. And immediately realised how bad my collimation was, the concenter revealed every fine-margin errors. That was exciting, with the errors visible, I can correct them. Concenter is like a Cheshire, but with an acrylic plate at the bottom with concentric circle patterns. 1st with the primary mirror covered up, i could accurately line up the secondary mirror to the focuser. Uncovering the primary mirror, the concentric circle patterns helped lining the primary to the secondary with ease. And finally tweaking the primary, the centre mark of the primary mirror Is reflected back correctly to the secondary. If you have seen how a Howie works, basically this tool attempts the same but instead of the convenience of having concentric circles projected onto the mirrors, you look through this tool to see the circles. i now love my light bucket photon eating 10” F4 Newtonian. think £70+ for this tool is a little expensive for what it is, but with so many DIY astronomers here with a 3D printer, you can fabricate this tool cheap and sell them

Am thrilled my little photo still receiving attentions 😁. I have plenty of noisy pictures that I hide from the world.

Thanks am surprised too with the clean data, largely luck to be honest, it was a absolutely perfect seeing night when I shot it, and I dithered every two frames it was shot with SW250 quattro, processed in Pixinsight. I followed a few YouTube tutorials as I don’t have a set work flow yet

Bortle 4, I use the astronomik cls filter which I think it’s pretty good

26 x 5 min exposure. Still loving my little 550d DSLR

Don’t know how I did it still, but straight out of the DSLR the stacked image was with minimal noise. Modded Canon 550d, CLS filter, SW250 Quattro with dedicated CC. 36 x 5min subs, flat/dark/bias calibrated

After having some fun with the Markarian’s Chain, the next night I turned my scope towards the Coma Galaxy Cluster. I stumbled across this area when randomly surfing on SkySafari and was mesmerised by how many visible-to-DSLR galaxies can exist in a single framable space I found it very hard to tease any colours out of my data, do you think I need few more hours of exposures for colours? Modded Canon 550d with CLS filter, SW250 Quattro CF with aplanatic CC. 36 x 5m exposures Would love any comments, especially how do you think I could get some colours in (more data?shorter exposure? ....)

Lovely, this is my plan target when the clouds clear bravo mate

so good, I am a little bit of a Newtonian Die hard fan, I think in good hands these cost effective scopes are every bit as good as £1k+ refractors what camera did you use?

Wow you got rid of the vignette sooooo good. I need to learn more on how to get rid of gradient. I just got myself photoshop so need to experiment a lot more

Markarian’s Chain, taken early March when a few clear nights presented themselves SW130pds, modded canon 550d with SW aplanatic CC, astronmik CLS filter, 2.5hrs worth of 5min subs, DSS stacked and PI processed with final touches in Lightroom. I recently started to use dithering and now I know what “dither or die” means

I am planning on capturing more data on a target I had done before last year do I stack old raw files with the new ones captured? Or can I actually stack the new raw files, with the single “stacked” output from the past raw files?

Oh yeah, and actually another prom at 3 o’clock, small needle (probably bigger than earth) only have a PST so playing around keeps finding new features

Quite a tall triangular prom at 8 o’clock region. Some surface details no sun spot

Beautiful, nice capture

Phewww least you saved the secondary!
