Fedele

I bought a TS 70/420 ED for some tests. As soon as I arrived it became normal for me to mount it very quickly in parallel to my FS60CB (60/360).

In visual the CB wins

First test of the Player One Astronomy Neptune C 2, at direct focus (f 12) of a Takahashi Mewlon 180c Recording was done with Sharpcap in RAW8. Unfortunately I did not realize that it was recording the single frames which I therefore had to preliminary stakk with Registax6, a program that I do not like very much. The result was then processed with my trusty AstroSurface T1.
I still have to understand the camera and considering that we are far from the optimal focal ratio, I think it will not make me regret the ASI224 which, however, I find easier to use with Asistudio and ASICAP.
The detachment of the ASi 178 MM seems evident, which however works better at direct focus than the baby-Mu, as well as being more performing because it is monochromatic (image below)

hi..can you help me to understand? i m not an expert

Player One Neptune 2 C and Sharpcap.
If i record the Sun  in MONO 8, when i load the ser both ans mono or any combination of Bayer option, i see the reticle. 
If i record in RAW 16 in Mono i see reticle, in Bayer just with some combination (as you can see in the attached images). 
If i record in RAW 24 i don t see reticle both in Mono or RGB. 
Whuat is the problem? explain me how is best to record becasue i m not expert of Sharpcap. 
Suggest me the best procedure to use this camera for planetary imaging. 
Thanks

A clarification, which I have mistakenly omitted. With Maxbright II Turret and Baader Cool Ceramic 2 ", you need a 1.7 GPC.
The alternative is to have me make a thinner flange

This was the first attempt

hi

I recently bought an FS60CB and I immediately ran into the known problems of backfocus and short focuser.
The use I have to make of the telescope involves the use of heavy and accessorie very demanding  in terms of backfocus: solar observations with Quark+ turret, Diagonals of 2", Baader cool Ceramic 2 "+ turret, etc ....
The definitive solution I found, which solves the focus problems with all this in a SAFE and STABLE way, was to mount an FTF 2025 BCR (which I had from the previous FC100DL). But not with the dedicated SI flange, as it takes up space and in the end the system is 7.5 cm long as with the original fok.
Therefore I had a flange made here in Italy, by the "Officine Otttiche e Meccaniche COMA di Adriano Lolli", which:
- was ultrashort
- that guarantees solidity to heavy optical trains without bending
- that he did not do vignetting
Lolli has created this magnificent flange which at the moment still has to be anodized in the same color as the focuser.
To give you an idea of the system, I go into focus with Maxbright II turret + T2 32 Baader + 2 "nose (total backfocus 148 mm) and there is still 22 mm of travel left, and this WITH NO GPC!

Solved. Is a first version, not SC compatible.

Hi

is the Mak 150 SW in the foto the second version SC compatible?
 

thanks

leave the images...i can see this directly at the EP. 

when i change the position of Dewschield the field change. 

is little more large when is out!!

How it is possible?

1) some sort of optic effects of the circular aperture of dewschield?

2) variation in focal lenght? so the triplet moves with Feeschield???? 

Optical effects of telescope's  Removable Dewshield
I hadn't fully realized it yet. On the night sky I had guessed it but I had never noticed it (forgive me if sometimes I don't pay attention to the laws of optics). The effect on the field of view of the lRemovable Dewshield position, out or not. 
Same setup: Takahashi TSA120 and Takahashi Abbe Ortho, photo with hand Iphone.
Don't mind the image quality as the telescope is indoors with heat coming out of the balcony. The photo of the cell phone obviously reflects what I see in the eyepiece. 
Another thing that I noticed, besides the slight variations in contrast, brightness and color (which I will quantify later, always on the same terrestrial subject), is the lower sensitivity to turbulence in the image with the Dewshield pulled out. The white lines inside the letters of the writing on the air conditioner are on average more clearly visible with the hood extracted. There are more "calm moment" to see.

Yes. Is another aberration?

Hi to all. 

I have a TSA120, a Mewlon 180c, a FS60CB
I have a whole series of eyepieces that I would like to replace. I currently have:
- n 2 Taka Abbe Ortho 32mm
- n 2 TV Ploss 25 mm
- n 2 taka Ortho 18 mm (my favorite eyepieces)
- n 2 FF 12mm (which I want to replace)
- n 2 Tala LE 7.5
- n 1 TOE 4 mm that I would like to double
other and various single EPs that I do not mention
In general, I love the large field even in high resolution. I bought with high hopes, two 19 mm Panoptics TVs thinking it was the right focal length to take into consideration. To my surprise on all telescopes they revealed a strong field curvature that I did not imagine at these levels. I like these eyepieces for their quality and compactness, but this problem bothers me when I look at the Moon or a cluster that takes up the whole field. On M42 they are perfect.
I was told that Pans don't introduce curvature, they simply capture more curved field of the telescope. this is true? i don't think.
would I have done better with 17mm Naglers?

2) do you recommend a double complete setup that can be used in the turret on all three instruments?
I thought:
n 1 ES 2 "68 ° 28 mm for the greatest possible field on Mewlon and usable on the other two in monoocular
n 2 Pan 19 mm precisely that I would now like to replace with Nagler 17 or ES to save money and which have less circulation

n 2 ES 11 mm 82 ° 31.8

add a 4 mm TOE
n 2 TOE 2,5 mm or you can suggest some other cheaper wide field eyepiece.

thanks
