You should post your pictures, don't mind how sophisticated are they. One of my best learning tools is to throw my pictures to the lions, I have tons of critics on my back I've learnt how to derotate planets by posting my pictures on astrobin. On cloudy nights I learnt a lot about the exposure times of my camera from the comments of my first pictures. I can go on with the list... I am subscribed to an Italian astrophotography forum as well and no matter how good your pictures is.. there will be always be somebody saying: "it looks very nice! But...". Anyway, I am opening my Flickr account! https://www.flickr.com/people/141331914@N07/

Thank you. I think you are right, I don't have the backported version. I will try it right away.

Hello everyone, while my previous installation of RSSVE was working fine, now I have a little problem with the RC4 version: I can't see Saturn's rings but everything else seems fine. To update from RC3 I unistalled EVE, Scatterer and RSSVE and updated everything with the versions suggested on the first post of this thread. Any idea about what could be causing this? Regards, Epox

Thank you and don't misunderstand me, I am not planning to stop posting DSO pictures here right now but I might if I'll keep posting alone. I appreciate that you like my work but I'd like to have the chance to appreciate the work of others too. Also that collaboration we spoke of: I have an hard disk full of data waiting to be shared if needed. We need a sharing platform and well... active sharers Winter is getting closer here, and a lot of cloudy nights are waiting for me, it would be nice to have some fresh data to work on even on those days. About astrobin, are you a user? If so what's your user name?

I'm on a target right now.. it's 3:30 am here.. finally a night without bombing clouds. The Moon made a brief appearance and now is set since a couple of hours. I think I have already enough data to get a decent picture out, now the target rose above 80' degrees and it's going to reach 89 later on.. I'm keeping an eye on the imaging train that might be touch the tripod as the it rises. The meridian flip will be at dawn so hopefully I can track until then without interruptions. Anyway, it's going to be a "little" suprise... and I've said enough. So here it is... (drum roll) : The Little Dumbell Nebula! It's still a work a in progress, I had some problem with calibration so I want to retake darks and bias and reprocess it. I also need probably to remove some exposure with elongated stars that came out at the beginning of the session while the target was low on the horizon and I need to integrate more data on a moonless night to try and take out the external part. The Technical Card is here I hope you like it and I take the occasion to state something: If no one else posts pictures here I will probably stop too. It would be nice to see someone else's work and talk about it... don't be shy! The summer is almost over and I didn't see any deep sky picture besides mine.

Sorry for the late reply I've been a bit busy lately ... no, unfortunately I had no chance. Cloudy weather on that day but anyway I don't know if I would be able to image such a tiny object at that distance So.. I had two clear nights in a row at the first one I won against the Pacman Nebula were I got a nice image from around 4 hours exposure (1.5 half our only for Hydrogen-alpha that makes most of the image), the second I lost against the Elephant Trunk Nebula and the galaxy NGC 925, my data are very faint and noisy still so I'm going to probably put them aside until I decide to integrate more data. Anyway here you can find the technical data about the Pacman Nebula and as well the full res image. I hope you'll like it! [/img]

I did 4 years of planetary with 2 laptops, one from 2003 with WinXp and the other one had Win7, it was newer but basically slower than my older one that was a high-end laptop at its times. Get the ASI, roll back to win7 and use the video crop function on your capturing programs to maximize the fps, you should be fine. Even if your camera does 30fps instead of 60 is more than enough. My old DMK21AU04.as had 640x480 resolution and 60 fps max but at 60fps it was showing artifacts so I always used it at max 30fps and I did the 99,99% of my planetary pictures with it

NGC 891 & Co.. the 2nd picture of my TS 8'' Ritchey–Chrétien. Technical Card And the picture: [/img]

So no eclipse pictures here????

Nope, absolutely nothing Thou a fellow Italian amateur astronomer will check up on the star soon, make pictures and compare them with older ones. If we will see the chance to make another report maybe we will do so.

I've update also the bicolor version with the new data: And.. .this might be a bit off topic but since In the past five years I've re-built a huge passion towards Space and Astronomy (it was a kid thing at start...30 years ago) I decided to go as deep as I possibly can and I thought that this might be a good start:

My first Hubble palette (SII,Ha,OIII)! 12 hours of exposure. Technical card: https://www.astrobin.com/307327/C/?nc=user And the picture:

I assume you have a 2 inch focuser? My asi290mm fits right into it. Also a 1,25' adapter for the focuser + something like this should do the job. Anyway... DSO-Browser staff posted my picture on their facebook page! They actually picked it from they website and posted it, isn't that cool?

Thank you! Oxigen is mapped to green and blue. The greenish/blue color should be obtained with the Hubble Palette (SII-Ha-OIII) and i still miss the SII channel. I applied the background extraction to both channels before combining. Also the background neutralization is a very nice tool and improved the contrast a lot. Consider that when I was taking this picture I could count just a bunch of stars and the sky was greyish. When I took the first picture of if, one week ago, the sky was dark and I could see an hint of the milky way which is a very rare event here , guiding was full of errors thou because of the strong wind.

Yesterday night I had finally a completely clear night, no stray cloud, no humidity.. just the full Moon but I was very happy anyway, it was low enough and shined over the scope for only 1 hour. So I managed to do my first color image from narrowband filter! The Image is Bicolor L-RGB (Ha-HaOIIIOIII) and 5.2 hours of integration (Ha 55x180sec - OIII 50x180sec) Technical card : http://www.astrobin.com/304991/F/?nc=user Oh! And by the way... I've "been" there a couple of year ago :

So... transparency was great as expected with such jet stream, I had wind gusts at 35 km/h, guide was going crazy but never broke (CGEM-DX ftw, it's a pier!). Not a single exposure was saved by the wind and in the end I didn't take bias, darks and flats but was happy anyway because I took confidence with the scope. The result is impressive: Tech Card: https://www.astrobin.com/304991/?nc=user And..... sorry but i had to post this too: https://youtu.be/VTmJJ0lUyQc

Very nice! What's better than a night with horrible seeing to test the rig? Tonight is expected a jet stream at approx 180km and 90% of humidity but I don't care. If I let tonight go, I'm sure I'll regret it later

Thanks! What did you see? Jupiter, Saturn and Andromeda maybe? I actually miss some planetary visual especially Saturn, I was used to dedicate some minutes watching it through the eyepiece before start to get pictures. Yes the design looks very nice indeed. Raw and sturdy. The TS version has also the focuser separate from the primary mirror, so no shifting during focusing which was a well known problem and widely reported (I think as well as the AT has this correction but I'm not sure if it is limited to the carbon version). I ordered a 0.67x astrophysics reducer which is know to be absolutely the best for the whole GSO RC series, so with the Newton at 600mm f/4, this one at 1088 f/5.4 or 1624 f/8 and the C11 at 1764mm f/6,3 or 2800 f/10 (maybe just for very small objects) I think I have a lot of possibilities. I am also planning to stack the 0.67 reducer over the coma corrector of my newton. It's a reducer for flat field telescopes (APO too) so my guess is if I use it correctly I don't see why It shouldn't work... moreover at 402mm at f2.7 who cares of some light loss . I maybe expect some illumination issue but we will see. And about the price, 839 Eur, there are very nice offers now on the RC series. The 6'' is at 399 Eur.

Arrived today, I need to wait for another package before being "Go for 1st Light":

I did it again, the family is getting bigger. I found an offer for the TS 8'' Ritchey Chretien and since it was in my wishlist, I didn't let it go. Now I'll have my personal Hubble ( .... the baffles... oh the baffles! https://youtu.be/bLLL1Jmf12U ) Also the Baader CCD set of NB filters is incoming.

@Green Baron Thank you, you are very kind. Yes I totally agree with you, it could be a normal fluctuation but who knows, the color difference is remarkable. I would consider a chromatic aberration a very unlikely possibility. Check this picture of the 5th of july (not mine): https://www.astrobin.com/full/302206/B/, I would be amazed if someone didn't notice it before. Anyway I felt like it was something to report. I believe the people I sent the information are very busy people and they need maybe more than a single report to move their telescopes. I haven't received any answer yet, I am not waiting for it but I am not letting this thing go either. Today I have sent them a plain-text email because I fear my previous emails might have been spam/filtered ( http://www.cbat.eps.harvard.edu/HowToReportDiscovery.html ). I reported what I have observed from my pictures and from the comparison with past and present pictures, the name of the star (this alone gives everything they need, It's not easy to find the name of any star you see) and I said that I will provide all the information I know as soon as I will receive a feedback from them. I really don't think I can do more than that Having acknowledgement would be great but let's say I am quite happy to have witnessed a celestial event, or even better a celestial event which would be invisible under normal circumstances (like looking at the sky with naked eyes). Edit: it would be great to have a spectroscopy of the star and someone actually able to read it

Anyway: Nova or not, here's the final version of NGC 7331 and Stephan's Quintet until I gather more data. I had some trouble with background brightness because of one of my monitor was badly calibrated but now it should be ok. Technical card: http://www.astrobin.com/301932/M/?nc=user

This is interesting. I was so excited about what I've noticed that I didn't even finish to process the image and I sent an Email to the Central Bureau for Astronomical Telegrams. The Image speaks for itself:

Surprise! NGC 7331 Group (The Deer Lick) and HGC 92 (Stephan's Quintet). Full res image and tech card: https://www.astrobin.com/301932/J/?nc=user

Another update on image annotation. Looks like that galaxy is in the 2MASS catalog which can be queried, downloaded and interfaced to Pixinsight. It seems difficult but in truth is extremely difficult, at least for me.. the deep space newbie :P. Anyway here's the reference: https://pixinsight.com/forum/index.php?topic=3966.75 (6th post from top)
