On a budget route. Although maybe someone can advise on how good they are... Search for Quadband DSLR filter. Maybe its a short term solution before you spend too much!! This should give good results in light polluted areas.

A great clear, dark night, last night. After imaging Abell 262 and gathering more data for M1 again I turned to NGC 3189 and NGC 3187. Part of the Hickson 44 galaxy group. I took 5 x 300s before settling on 600s subs, of which I managed 20 more subs. I did a quick process to see how it would look. The data looks good, its my processing that requires more care

Equipment - C11 @2800mm, Atik 4120EX OSC with IDAS LP filter. Lodestar X2 on ZWO OAG. All sat on a Mesu 200.

Software -SGPro and PixInsight.

Thanks for looking.

Can I suggest this as an idea?

Congratulations to all the winners. Some great images there. Well done.👍

Hubble public data

Go to the site. Right down the bottom of page it says Enter Here...click that!

Type in the Messier, Say, M1 or some other .... work it out from there.

Enjoy

Dead column ???

OUCH!!!

Can you get it fixed/replaced ?

If the weather was clear skies 250 nights of the year it would be perfect in the Cairngorms National Park. 

Could you imagine imaging from 4pm until 7am during winter  WOW!!!

Its a great idea and not so far to travel too. Fun to dream about.

However, I'm sure there are a few sites in Spain/France etc, with many more clear night skies, that one can setup a remote Obsy, fly/drive back and forth from UK for a few years and still have change out of £700,000

I would try again when the seeing conditions improve.

While waiting for the seeing to improve - Collimation is one thing to look at. Find a bright star first. Once happy it looks collimated. Try a dimmer star and check again. Also, check stars at the four corners of the image. Don't drive yourself crazy though lol.

I do find my C11 is great for deep sky stuff but always find it does not show the contrast that my APO shows when imaging the moon.

Good luck.

Great image Göran and nice processing too. 

I was hoping to use iTelescope to image some thing in the Southern Hemisphere this weekend due to the cloud cover here but so far have not decided on a target.

I need to check out the Liverpool Telescope public data sometime.

If yours has Fastar (Hyperstar), the secondary mirror is removable. Have them remove it to check it is not stuck!  While its out, check there are no marks on that mirror too.

Thanks for your informative review Matt.

I have been subscribing to iTelescope for some time now on the lowest rate (£15/month?) Having my own setup in my ROR Shed, I don't use iTelescope much. However, with the cloud cover at the moment not showing any signs of lifting I will use iTelescope again these coming days.

When I have used iTelescope in the past, any issues have been resolved very promptly with no problems getting anything sorted. TBH, I cant even remember what it was lol.

I do like iTelescope. The variety and quality of the equipment at ones disposal. My last image of M16 was taken using a rig probably costing over £40k. Way beyond my size pockets. Value for money in my eyes

And last of all....Chance of far battery skies and lower light pollution than my back yard

My next target as well thanks for posting

What gain did u set for the 183 ? i used 2min exposures on M76 at gain 111 and felt the inner details were blown out . it was luminance only as well

thanks

 

I used Gain 111 for this Lum

Very nice image.

Thanks for sharing.

Looking good so far Rodd. Hope the weather picks up soon so you can continue.

I looked forward to seeing this develop.

I was watching a interesting documentary on NETFLIX called "A Year In Antarctica". 2/3 into the film they show lots of night shots of the clear star filled sky. And yes, one can see many satellites passing over head as its the South Pole. But at one moment I see maybe 5 satellites passing VERY close to each other from different directions. I am aware of parallax and for 5 satellites, there's a lot of room. But there has to be some sort of limit to how many one can have flying around and not bumping into one another!!

The last thing anyone wants is for satellite junk out of control. That would be very dangerous for future astronauts  As well as messing up my imagining routine!!

Very nice.  I was looking at this yesterday as a possible target, so it's nice to see this.  You've got some nice detail in some of the spirals, so it's definitely on my list now.  Thanks for posting.

You are welcome don41.  Thanks, that's exactly why I posted.

The ASI183MM Pro is a great camera. I overexposed on this so wanted to let others know/check. There are lots great galaxies to be seen here at the right focal length. Personally, I will be trying again at shorter exposures with my ASI183MM Pro. as and when we get clear skies and no moon lol.

Thanks for sharing Dave.

I have not seen this yet. Looking at this GIF. Its not that easy to spot in action. The GIF does highlight it.

Taken 29 Sept, but only just got around to processing.  Just a quick process at that.

Looks to me that 120s exposure is too much for the camera using the ZWO ASI183mm Pro on the TS65Q as the center of the galaxies look a little blown out. But hey, I thought I would post anyway  There's a lot of galaxies in there  

Next time I will use 60s...if we get clear skies again !

Thanks for looking.

A word of caution. The advert, as I read it, does not say if it has disks/SSD's or memory! It only states that it can accept them. You will have to add the disk and memory...adding to the cost. ..................If it does come with SDD/Disk and 4Gb or more memory then it looks OK....But check first!

Fantastic news 

I presently subscribe to some online scope time renting service at the moment due to the inclement weather here in the UK. I would be very interested in seeing this project up and working ASAP, even if the acquired image data is made public.  Its all fun stuff....and some scientific too, makes it even more interesting.

Very nice image Adam.

Whats the issue with Lum to RGB?

I have a small dehumidifier running and a green house heater to keep the ROR Shed dry. 

I'm not too sure about Domes but my ROR Shed has plenty of fresh air circulating. Since I took my C11 from standing in the garden to inside a permanent ror shed I have not had condensation/moisture issues.

If your C14 has Fastar, try removing the secondary mirror and removing the eyepiece from the other end. Use a cool hairdryer to blow air through the C14 to help remove the moisture! I have used this trick on my C11 a few times in the past and it works fine the rest of the night  

Welcome to the Forum Dave.

The Bins may need collimating. Adjusting a screw near the prism. Maybe mention it in another thread and I'm sure plenty will explain how to set the Bins up so you see straight  

I agree with Carole. See my avatar.

I left my scope out for 18 months. Covered with a BBQ cover and tied underneath. I did however, remove the covers, even when not in use, just to air it off now and then. Never had issues really. I did remove the front mirror a couple of times to speed up the drying process after a very damp, wet, week. But never caused any lasting damage. The scope is now in a ROR Shed, same place as in the Avatar..I just built the obsy there instead

Don't leave cameras out all the time though. They will succumb to the elements very quickly.
