Yes, I figured out that I wanted to try out two different filters, and due to my laziness and interest for electronics, I purchased the seven holed filterwheel from ZWO. Also because if I suddenly want to purchase a mono camera. Anyways, I think I’ll stick to the colorized version first and make that work good first 😊

@Ouroboros I am just very new to this, so I tough I needed long exposure time to get the faint areas. some other settings I used, where; Gain: 40 Dithering (1) default. Mount: EQ6R Pro @Lee_P , I’ll try 2 mins.. What Gain settings do you use? the stuff:

Starting yeaterday evening, I tried to capture the NGC7000 with my ASI2600MC on the Skywatcher Esprit 120ED with zwo duo-band filer. I used ASIAiR pro for capturing lights, flats, bias and darks. And stacked them in ASI Studio. the settings I used where 10minutes x 20. I had to throw away 12 of the images due to clouds and one due to satelite flybys.. I was a bit disappointed, since I just got alot of stars, and some nebula. But I guess that I need a less focal length than 840mm for that nebula. And pehaps shorter time than 10 minutes?? This is the jpeg that ASI Deepstacker created;

12,5 mm is exact at the protective glass of the sensor as I can see it. It also confirm some of my cleaning work, as it was the protective glass that had most particles on it. I suspect that when I turn the filterwheel, it might whirl up and add additional dust since I must have 60+ degrees on polar alignment (Live up north) (Which also make the scope tilting upwards alot, and so making the sensor protective glass as a dust collector 😳 ) Here is the camera spec: I had to remove the 5mm on top to be able to attach the filterwheel:

Wow... Please just relax and make yourself ready for surgeon. I can wait, no need to rush.. The stars out there will probably be there next week also 🙂 I struggled a bit to find a program that could take one FITS file and save it to JPG. Many programs only displayed grey, and not the FITS image. The ASIFitsView from ZWO only views the file... Anyways, I found one software; "KStars FITS Viewer". That one displayed the FIT'file correctly and made it possible to save the file to both JPG and PNG. I uploaded both: JPG (4.5 MB): PNG (35.2 MB):

It is still impressive 👍 You probably learnt alot underway, and sometimes that is the most valuable output!

Thats quite cool and impressive! And….how many hours did it take from starting the build, trial and error, to end? 😊

Thank you @steppenwolf !! That is quite cool!! How do you do that?? I did not find the actual frame, but I took several turning the mount over and up/down, so attached a similar, same night- This is the preview image. The original FITS (It is quite big!! Preview_10.0ms_Bin1_1.fit This is preview of another noe after trying my best to remove the dust. This one, I used binning (Bin4) Still have a spot in upper left: Full FITS file (Bin4): Preview_30.0s_Bin4_3.fit

Thank you all for the answers. I really appreciate the help! @tomato Thanks for the advice. I just ordered it from FLO. Also added in a book on preprosessing: «Dark Art or Magic Bullet» by Steve Richards. Best regards, Martin

No, I am just using ASIAir for now. I have not dived into photo editing programs….yet. I do have Adobe photoshop and lightroom, which I use for «ordinary daytime photos». But, I’ll check out NINA. Thanks.

I did a new cleaning of the camera and the filter. Now I have everything on side, bright light and a magnifying glass… I really struggle to get all dust grains off, but I felt I was getting somewhere now.. It is still cloudy (will be that for the next 14 days), so it was blank photos. I notice that the spots are more visible with long exposures. I took 1sec (no dots), 30 sec (faint dot upper left), 300 sec (clearly visible dot upper left.) Also moved the scope angles, but the dots where at same spots. So, I guess I have to learn shooting flats?? 😳 asi2600mc, 1 sec (no dots): Asi2600mc, 30 sec (nearly visible dot) Asi2600mc 300sec (visible dot) camera setting for the asi2600mc; the gear. (I am still waiting for a dove tail to fit the asiair to, so it is a bit messy now). High angle to polar star (61degrees), since I am in Norway.

Thanks for answer. For the ASI120 photo, I did not use filter. For the ASI2600, I tried with one filter and no filter. Same spots. Are those rings created by dust? They seem so perfect round. I tought dust was more blurry.

Hi. Newbie question here; I have just purchased a Skywatcher Esprit 120ED triple APO, and an ASI120mini, and today an ASI2600mc. I first tried the ASI120mm mounted, and took some shots at the pinwheel galaxy a couple of days ago. I got a dot in every photo as you can see, but didn’t bother since I was waiting for the ASI2600. Then, today I tried out the ASI2600mc (in daylight and cloudy wheather), and I got similar dots. I tried to clean the front of the scope, the flattener and the asi2600mc, but the dots keep coming. How do I get rid of them?? ASI120mm: ASI2600mc:

Hello folks! I decided to register here since I just have bought an Skywatcher EQ6-R mount and a Skywatcher Espirit 120ED. And my knowledge of astrophotography are equal to almost zero. I guess I will have a steep learning curve. 🙂 Best Regards, Martin
