Does the little Redcat 51 tick the box for you? That's 250mm focal length so might be too wide for what you're looking for? Phil

My first Veil Nebula, and test of the L-Ultimate
Phillyo replied to Smiller's topic in Imaging - Deep Sky
Oh absolutely, total combined exposure time is key. I'd rather deal with fewer 5min subs than more 10 second subs for sure. Just impressive the level of detail collected from such short sub lengths. -

Phillyo replied to Smiller's topic in Imaging - Deep Sky
It's bonkers you can get so much detail from just 6 second subs. It makes you wonder about the need for 5min or 10min subs. Great images, this and the crescent nebula are both gorgeous. Phil -
That's a really nice setup! Roughly where in Lincolnshire are you? It would be lovely to pop round sometime and see how you have everything connected etc. Feel free to private message if you want, or if you'd prefer not to, just in case, that's also cool! Phil

Very nice image! I've just bought a Redcat 51 and I'm also in Lincoln so I'm looking forward to seeing what I can get with this combo Phil

I already use a Mini PC and it works fine, I love it. I was just curious about the ASIAIR type of ecosystem more than anything else. It is very handy
-
I'm just curious as to why there are no other manufacturers making something similar, especially one that is open to ALL cameras/guiders etc rather than being locked to a single ecosystem. It seems that they are very popular (I liked mine while I had it) but are let down by locking people into using only ZWO equipment? Or have I missed something Phil

Imaging with the Samyang 135mm f2
Phillyo replied to Uranium235's topic in Getting Started With Imaging
You're not the first person to tell me that! That's the first thing my Mrs said when she saw it lol -
Located in the constellation of Auriga, the Flaming Star Nebula (IC405, SH2-229 or Caldwell 31) is approximately 1500 light years away. The Tadpoles (IC410) are located at approximately 12,000 light years, so despite looking like neighbours, these two are not. Captured with the Samyang135, Risingcam IMX571c, Antlia ALP-T 5nm filter, EQ6r Pro, NINA, PHD2. Processed in Pixinsight. This is approx 14.5 hours of data. I'd like to have rotated the camera/lens 90 degrees for better framing but it's a faff so I didn't bother Thanks for looking.

Possibly, but you should have removed those frames from the set before stacking the data no?

Imaging with the Samyang 135mm f2
Phillyo replied to Uranium235's topic in Getting Started With Imaging
Just wondering, how do you guys rotate your lens and camera to get the correct framing of your target? Or do you just set it and leave it and hope for the best? Any tips/tricks for easy rotation and framing? -
I've just done the same on a single sub and 15 hours of exposure stacked. Difference is 25db for single sub and 49db for 15 hours? Whatever that means!

Not a clue

It looks like your focus is slightly off, I'd work on getting accurate focus first. Leave gain and offset to defaults, not much to be gained by changing them really.

Yes, that one. Thank you -
Imaging with the Samyang 135mm f2
Phillyo replied to Uranium235's topic in Getting Started With Imaging
I followed a youtube video on modifying the backstop. I added it to another post somewhere else on the forum where Olly was making a new Samyang rig if you can find that? I'll see if I can find it for you. It's very easy to do. -
Imaging with the Samyang 135mm f2
Phillyo replied to Uranium235's topic in Getting Started With Imaging
Mine was so close that I couldn't actually achieve accurate focus with one filter, that's why I had to modify the lens a little bit. -
Imaging with the Samyang 135mm f2
Phillyo replied to Uranium235's topic in Getting Started With Imaging
Ah, well it varies depending which filter I have in. However off the top of my head I don't know lol, I'll check tomorrow when I cover it up again. I use an EAF with it so I never really notice/care any more. Sorry! -
C/2022 E3 (ZTF)
Phillyo replied to peter shah's topic in Imaging - Widefield, Special Events and Comets
Peter, question if I may. When you take images like this of comets, do you just slew to it and track the sky using sidereal rate as normal or do you need to have the telescope track the comet instead? I'm assuming if you're only taking lots of short subs then normal sidereal rate will be correct but I have no idea as I've never taken a photo of a comet before and I'd like to give it a go tonight. Fantastic image!! Love the detail in the tail of the comet. -
Imaging with the Samyang 135mm f2
Phillyo replied to Uranium235's topic in Getting Started With Imaging
This is a widefield view of NGC2264, the Cone Nebula. It's forms the top part of a two panel mosaic I'm working on to try and incorporate the Rosette Nebula too. I need more time on the bottom panel though, only 8 hours so far. This is 15 hours of data shot in 3min subs through my Samyang 135@f3.4 and my Risingcam IMX571 camera, through the Antlia ALP-T 5nm Dual Narrowband filter. There's a LOT going on in this area, as you can see in the starless version. I'm very tempted to keep adding to this and see how much more I can bring out? I've left the background fairly light here to show the faint details around the main nebula but it does mean there's a little more noise present in the image too. Phil -

Phillyo replied to Uranium235's topic in Getting Started With Imaging
I had to doctor the lens and remove the hard stop to achieve accurate V-curve via autofocus. -
Thank you both. I'm curious as to what that large O3 looking bubble is at the bottom left of the image? Astrobin platesolve hasn't given it any kind of identifier.
