I am done with these cheap cameras, other than for planets. Getting an QHY 163C much wider field of view, cooled also a big advantage and with a 0.5x can get 1.5 moons in field of view, so much easier and far better more senstive chip. You get what you pay for.

Difference between cheap planetary camera and a much better one.

Yeah, there's always a tradeoff.

Combine a 150 dollar mono sv305 guide cam (maybe $150 price?) With the new Sv405c (cooled deep space camera, maybe $400-500?) You have a decent deep space starter set for 550 to 650 dollars. Zwo equivalent for these sensors are $800 (zwo533) plus $300 (zwo290). I can see the appeal for starting imaging. They should release mono and colored versions. Give them time.

Robodan

You are comparing two cameras with different chips with different sizes of sensor and pixels. That had nothing to do with cheap vs expensive. If zwo or sv bony released that camera chip at a cheaper price your field of view would be the same. Now the thing that would matter is build quality, driver quality, and customer support.

Finally got a chance to shoot M42 under Bortle 4/5 skies instead of Bortle 8/9. My chief complaints about it are that the gain is too high, so the bright stars turned into blue marbles and I wish I'd framed the image so that Running Man showed up better.

Looking good. It will be hard not to get color abberations and halos with that scope. Dont fret your probably getting more out of that setup than most.

So I'm a complete beginner with taking any kind of astro photos.  I have an EQR6 Pro as a mount an a 200mm F/5 newt as a scope and the Svbony 305 as a camera to play with.  

 

I took a stab at NG 7331 a month or so ago, but after the snow and sub 0 temps passed it is now out of view for me by the time it gets dark.  Anyway, this is what I was able to accomplish with a few hours worth of photos, it was my first attempt and I know I had bad focus for at least one session.

 

I'm currently trying to gather data for NGC 891.  I've done OK with the newt, but switched gears and decided to try out with my 102mm Achro refractor.  I have a couple nights data with each scope and doing a compare contrast of the results from each to see which I like working with better.  I will post some results once I process each.

The problem here is that you need a UV cut filter. Fair warning, the cheap SVBONY IR/UV cut filter you may be considering seems like a hunk of transparent glass to me.

I was under the impression that the SV305 had a UV filter in place already.

That was based on some email exchanges with SVBony as I asked them if I could remove it - they couldn't understand why I wanted to do that.

Cheers

I may be wrong, but I believe that the AR window is only IR cut on the SV305, not UV cut. Given your (and my) results with bright blue stars, I am virtually certain of it.

Hi Borodog, This is the email exchange I had with SVBony:

 

the SV305 coming with a UV IR Cut filter.
yes, the bandwidth is same with your picture.

if you want to remove it, then you need Disassemble the SV305.
because the filter is inside and Stuck inside the shell.

What target do you want to capture?
the SV305 camera is a planetary camera. so we add the UV IR cut filter on it.
thanks for your reply.

 

They certainly mention UV and IR together. I guess that would mean it filters both UV and IR?

 

Cheers

Hey everyone, I just purchased this guidescope (SVBONY SV165) and I'm wondering if I need an adaptor to mount it to my Sharpstar. The sharpstar itself has a rail on it, but from the guidescope it looks like the end of it, needs some sort of dovetail adaptor?

 

If you can see it, this is the top of the scope that I have...not sure how the SBONY can fit on this...

Unfortunately, that thumbnail didn't load. Does it look like this with both the dovetail and the bracket or just the bracket? I don't own the SV165, but according to the product page it has a dovetail, but also a 1/4" threaded hole. If your scope has just the bracket (no dovetail receiver), then you should be able to attach a dovetail receiver to the bracket. Something like this.
