Figure & Nr. when Sidecap is used in a scrreprt

Question

I use the scrreprt document class. I wanted to use the sidecap package for side caption.

As you can see here, since all the caption is after (right of) the "Figure & Nr:" it takes away a lot of space.

I guess this is due because the way scrreprt document class makes figures. I would like to either have the second line of caption starting underneath the "Figure 2.3:" or to have the "Figure 2.3:" over the caption.

I hope you understand may problem. If you need a minimal working example just ask. Thanks

Edit:

MWE:

\documentclass[a4paper]{scrreprt} 
\usepackage[english]{babel}
\usepackage{graphicx}
\usepackage[outercaption]{sidecap}
\usepackage{blindtext}

\begin{document}
\chapter{Test}
\begin{SCfigure}[50][h]
    \caption{\blindtext}
    \includegraphics[width=0.5\textwidth]{example-image-a}
    \label{}
\end{SCfigure}
\end{document}

The gap between the Figure and the caption (caused by the "Figure1.1:" is not really space efficient.

Answer 1

With the caption package you can change the format of the side caption:

\documentclass[a4paper]{scrreprt} 
\usepackage[english]{babel}
\usepackage{graphicx}

\usepackage{caption}

\usepackage[outercaption]{sidecap}
\captionsetup[SCfigure]{format=plain}
\usepackage{blindtext}

\begin{document}
\chapter{Test}
\begin{SCfigure}[50][h]
    \caption{\blindtext}
    \includegraphics[width=0.5\textwidth]{example-image}
    \label{}
\end{SCfigure}
\end{document}

Answer 2

With scrreprt you can also use environment captionbeside which is provided by the KOMA-Script class:

\documentclass{scrreprt} 
\usepackage[english]{babel}
\usepackage{graphicx}

\usepackage{etoolbox}
\BeforeBeginEnvironment{captionbeside}{\setcapindent{0pt}}
\KOMAoptions{captions=outerbeside}
\usepackage{blindtext}% only for dummy text

\begin{document}
\chapter{Test}
\begin{figure}[hb]
  \begin{captionbeside}{\blindtext\label{}}
    \includegraphics[width=0.5\textwidth]{example-image}
  \end{captionbeside}
\end{figure}
\end{document}

Result:
